Xanthelasmas are localized accumulations of lipids, mainly cholesterol, that can occur in the epidermis, dermis, and muscle of the eyelids. They are the most common cutaneous presentation of xanthoma and occur most commonly on the upper eyelid near the inner canthus. Despite their benign presence, xanthelasmas can be cosmetically concerning. With this in mind, several treatment modalities have been described to eliminate the appearance. We report the first case to describe a cicatricial ectropion from the topical treatment, "Glycolic acid, Lactic acid, Mandelic acid, Salicylic acid, Resorcinol, Jessners peel" (XanthelR, 483 Green Lanes, London, N13 4BS).

PURPOSE While Wendell Hughes popularized the tarsoconjunctival flap for lower eyelid reconstruction, most modern procedures are derived from the technique described by Kollner in 1911. This study reviews the history, techniques, and outcomes of a large series of patients treated with a modified Kollner flap. METHODS In this observational cohort study, medical records and photographs were reviewed in patients undergoing surgery between 2005 and 2020. Patient demographics, complications, secondary interventions, and outcomes were evaluated. RESULTS Marginal defect size ranged from 12 to 41 mm among the 140 study patients. Ancillary procedures included lower eyelid conjunctival flaps (n = 64) and septal orbicularis flaps (n = 68). The anterior lamella was reconstructed with skin grafts (n = 86), flaps (n = 10), or combined flaps/grafts (n = 44). Pedicle division was performed 23 to 84 days after primary repair. Subsequent interventions included steroid injection (n = 10), cryotherapy (n = 10), marginal erythema treatment (n = 9), and upper eyelid retraction repair (n = 6). Tearing (6.5%) and dryness (10%) were the most common postoperative symptoms, with most patients (78.6%) being asymptomatic. A good-excellent functional outcome was achieved in 94.3% and cosmetic outcome in 85.0% of cases. Defects

This study analyzed the blink characteristics of patients with incomplete and complete facial paralysis. The authors measured and compared the palpebral distance, eyelid movement distance, and the eye-closing ratio of blinks in 55 patients with Bell's palsy or Ramsay Hunt syndrome (Bell & Hunt group) and 14 with complete paralysis (Complete Paralysis group). In the Bell & Hunt group, the palpebral distance (7.94 mm) was smaller on the paralyzed side than on the non-paralyzed side (9.61 mm). The eye-closing ratio and the upper eyelid movement were reduced on the paralyzed side (65.3% versus 93.7%, 4.61 versus 7.97 mm) and in the Complete Paralysis group (25.3% versus 94.7%, 2.10 versus 8.49 mm). In the Bell & Hunt group, movement of the upper eyelid on the paralyzed side was weakened despite palpebral contracture. The Complete Paralysis group exhibited highly reduced movement in both the upper and lower eyelids.

PURPOSE Lid wiper epitheliopathy (LWE) is an epitheliopathy of the marginal conjunctival portion of the eyelids that wipes the ocular surface during blinking. Although LWE is often observed in patients with dry eye, the factors determining LWE severity in dry eye remain unknown. Therefore, we investigated the relationship between LWE, tear abnormalities, and blinks in dry eye. METHODS This study involved 76 eyes of 76 female patients with dry eye (mean age: 57.2 yrs). In all eyes, tear meniscus radius, spread grade (SG) of the tear film lipid layer (ie, SG 1-5, with 1 being the best), fluorescein breakup time (FBUT), fluorescein breakup pattern, corneal and bulbar conjunctival epithelial damage (CED: 15 points maximum; CjED: 6 points maximum, respectively), upper eyelid LWE grade (3 points maximum), and Schirmer 1 test were evaluated. Blink rate, palpebral aperture height, upper eyelid opening/closing-phase amplitude, upper eyelid opening/closing-phase duration, and upper eyelid opening/closing-phase maximum velocity were measured by the use of a custom-made high-speed blink analyzer. Finally, the factors that determine the LWE grade were investigated by multiple regression analysis, in which the parameters were chosen using the stepwise procedure. RESULTS Significant correlations were found between LWE grade and tear meniscus radius, SG, FBUT, CED, CjED, and Schirmer 1 test (P < 0.002). LWE grade was found to be described as -0.001 + (0.283 × SG) - (0.253 × FBUT) + (0.003 × upper eyelid closing-phase maximum velocity) (R2 = 0.57, P < 0.0001). The prevalence and grade of LWE were significantly higher in aqueous deficient dry eye. CONCLUSIONS Tear volume, tear film stability, and blink should be considered as factors for determining LWE severity.

BACKGROUND Lid fatigability test (LFT), Cogan lid twitch (CLT), and forced eyelids closure test (FECT) are simple clinical screening tests for ocular myasthenia gravis (OMG). However, these tests are subjectively interpreted. We thus evaluated the interobserver and intra-observer reliability of each test. METHODS The 3 eyelid tests were performed in ptotic patients associated with various conditions, including OMG and others. Video clips of all tests were recorded using smartphone with built-in camera in the following order; LFT, CLT, and FECT. All video clips were distributed to 3 neuro-ophthalmologists and 3 general ophthalmologists, who were trained to evaluate the tests using a single standard instruction. After 3 months, all video clips were re-organized for the second evaluation. Interobserver and intra-observer reliability were calculated using Cohens' Kappa coefficient and Fleiss Kappa statistic. RESULTS The 3 eyelid tests were performed and recorded in 35 patients, which included the diagnosis of OMG, levator muscle dehiscence, partial oculomotor nerve palsy, and Horner syndrome. CLT received moderate-to-substantial interobserver reliability in neuro-ophthalmologist group (Fleiss Kappa 0.77 [95% CI 0.60-0.94] and 0.66 [95% CI 0.46-0.85] in first and second evaluation respectively), but the results varied in general ophthalmologist group (Fleiss Kappa 0.58 [95% CI 0.37-0.79] and 0.54 [95% CI 0.33-0.76] in first and second evaluation respectively). FECT and LFT received lower interobserver reliability in both groups. CLT also received moderate-to-almost perfect intra-observer reliability in neuro-ophthalmologist group (Cohen Kappa 0.55, 0.58, and 0.92), whereas FECT and LFT received lower intra-observer reliability. The intra-observer reliability varied among general ophthalmologists for all 3 eyelid tests. CONCLUSIONS CLT is the most reliable test among the 3 eyelid tests. However, all tests should be interpreted with caution by general ophthalmologists.

Significance Ptosis is often the hallmark finding in ocular and general myasthenia gravis. Reduction of ptosis has been achieved with oral and topical ocular medications. However, these medications can result in systemic and ocular side effects. A novel eye drop appears to be effective in reducing ptosis while minimizing side effects. Purpose This case report aimed to demonstrate the efficacy of topical oxymetazoline hydrochloride 0.1%, an alpha-adrenergic agonist in temporary elimination of ptosis associated with myasthenia gravis. Case report A 68-year-old female with a history of myasthenia gravis and longstanding ptosis in the right eye presented to improve the asymmetrical appearance of her eyelids. One drop of oxymetazoline hydrochloride 0.1% was instilled in the right eye of the patient. Within two hours, the ptosis was eliminated, the margin-reflex distance 1 increased by 2.0 mm, and the superior visual field measured by a superior 36-point screening test increased by 15 points. The effect lasted for at least 7 hours. Of note, there was a decrease in elevation of the contralateral non-ptotic eyelid that did not receive a drop of oxymetazoline, which might occur only in myasthenia gravis. Further evaluation is warranted. Conclusions Oxymetazoline 0.1% is effective in reducing and potentially eliminating ptosis related to ocular myasthenia gravis for up to 7 hours.

The predominant method for transconjunctival orbital fat transposition is by conducting 1 or several temporary externalized sutures. A new method that could internally and more securely fixate the fat to the periosteum remains desirable. This manuscript introduces a technique that utilizes a titanium ring to guide transconjunctival orbital fat fixation for lower blepharoplasty. With 8 to 10 mm transconjunctival incisions, the orbicularis retaining ligaments were released. An intraoperatively made ring guided the sutures that was made transcutaneously and anchored on the periosteum to exit the preseptal space through the transconjunctival incision. The orbital fat graft was then fixated internally by this suture. From October 2017 to November 2019, 51 patients were included in this study. The mean patient age was 35.7 years (ranged 28-42 years). The mean operative time for the surgical procedure was 52 minutes. No major complications were noticed in any patients. There was 1 case in which the eye bag relapses at fifth week postoperatively, but was corrected by the same approach. At the average follow-up period of 12.1 months, all patients presented significant improvement of the lower eyelid cosmesis. Forty-four patients rated the aesthetic outcomes as "Very Satisfied," the other 7 rated "Satisfied" in a self-assessment questionnaire.Global Aesthetic Improvement Scale echoed similar outcomes. This guided internal fixation technique is technically practical when properly executed. It offers a new method for facilitating orbital fat transposition in lower blepharoplasty.

Objective Upper eyelid laxity affects facial aesthetics and the eyebrow arch in the East Asian population is generally low. The authors developed infraeyebrow blepharoplasty using a dynamic suspension technique between the dermis-fascia flap and frontalis for upper eyelid lifting and eyebrow augmentation. Methods A retrospective study was performed on 43 female patients with upper eyelid laxity from August 2015 to October 2019. The epidermis and superficial dermis of the infraeyebrow was removed from the surgical marking area with the deep dermis and fascia preserved. The eyebrow skin flap was separated from the frontalis surface which fully exposed the area around eyebrow arch. The preserved dermis-fascia flap was folded and suspended to frontalis in the superior margin of eyebrow arch. Results Forty-three patients (median age 54 years [range, 38-70]) underwent this operation. Mean follow-up was 25 months (range, 8-42) was assessed. All incisions healed well and were almost invisible. The eyebrow area improved with upper eyelid skin lift and eyebrow augmentation; 40 cases were "very satisfied" with their appearance. Three cases were "not very satisfied," including 1 case with numbness in surgical area. 2 cases had slight bilateral asymmetry of the upper eyelids. Conclusions The dynamic suspension technique is worthy of clinical application because it can correct upper eyelid laxity, augment the low eyebrow arch, and obtain an invisible scar by reducing the incision tension.

Background Static eyelid reconstruction surgery, such as ptosis repair or brow lift, is widely performed for patients with facial paralysis. Complications include exposure keratitis and possible vision loss mainly due to eyelid closure impairment in spontaneous blinking. However, no quantitative evaluation data has been available regarding postoperative closure deterioration. Methods To elucidate factors associated with postoperative eyelid closure impairment, a retrospective study was performed for 51 patients who underwent an initial static eyelid reconstruction surgery from October 2017 to August 2020. A static eyelid reconstruction surgery consisted of either 1 or more of the following: (1) levator advancement, (2) brow lift, and (3) orbicularis oculi myectomy. Eyelid closure ratios (0% for complete closure impairment and 100% for perfect closure) at spontaneous blinks were measured on 6 occasions: before operation and at postoperative 1, 3, 6, 9, and 12 months. Comparison was made between preoperative and postoperative values by using mixed-effects model. Results Overall, average closure ratio was significantly increased. However, 10 patients had >10% closure ratio decreases at at least 1 postoperative measurement point, and all those patients had undergone brow lift procedures. Conclusions Although eyelid closure at spontaneous blinks may, contrary to assumptions, generally be improved after static eyelid reconstruction surgery, brow lift was suggested to be associated with eyelid closure impairment.

AIM To describe a series of medial canthal defect reconstruction by local/loco-regional flaps following excision of basal cell carcinoma. MATERIAL AND METHODS A series of 35 medial canthal defects following excision of basal cell carcinoma was reconstructed by local/loco-regional flaps. For smaller defects, glabellar lateral advancement flap or Limberg's flap from the nasolabial area were used to resurface the defects. For larger defects extending to the upper and lower eyelid or to the nose, a combination of flaps, that is, forehead and cheek rotation flaps or glabellar and cheek rotation flaps were used. RESULT In all the cases, the aesthetic and functional results were highly satisfactory except in one, where punctum and lower canaliculi were also excised with the tumor for clearance. This patient complained of watering from the affected eye. Two patients had developed webbing after the operation. It was corrected by Z plasty after 6 months. CONCLUSION Medial canthal defects are best managed by local/loco-regional flaps. For smaller defects in the upper part, the glabellar flap is the choice of the flap and in the lower part, flaps from the nasolabial region give the best result. For larger defects not amenable to single flap, a combination of flaps (glabellar/forehead flap and cheek rotation flap) can close the defects with the good aesthetic and functional results.

OBJECTIVE This study aims to evaluate the clinical effect of modified maximal levator palpebrae superioris shortening method for severe congenital ptosis. METHODS A retrospective case series was performed including 66 eyes from 62 patients who underwent modified maximal levator palpebrae superioris shortening surgery to treat severe congenital ptosis between February 2015 and November 2018. Preoperative and postoperative margin reflex distance 1 and levator muscle function were recorded. The surgical results were graded as good, satisfied, and poor for functional and cosmetic improvement of the eyelids, and the incidence of complications was also documented. RESULTS The mean patient age at the time of surgery was 4.6 ± 1.8 years (2-9 years), and the mean follow-up time was 36.3 ± 14.1 (12-55 months). A mean significant improvement in margin reflex distance 1 and levator function after operation was noted (P < 0.01). The eyelid height and symmetry were satisfied in 59 patients, with success rate of 95.2%. For the patients in the levator function (≤2 mm) group, the success rate was 87.5%. Moreover, the levator function (≤2 mm) group had a higher rate of poor results than levator function (2-4 mm) group (12.5% vs 2.2%). Overcorrection (6.5%) and eyelid fold deformity (11.3%) were the most frequent postoperative complications. CONCLUSION Modified maximal levator palpebrae superioris shortening was effective and endurable in the treatment of severe congenital ptosis with poor levator function, including in patients whose levator function was less than 2 mm.

Purpose To assess the long-term effectiveness of the orbital septal flap to lengthen the levator muscle in management of moderate and severe upper eyelid retraction. Methods This study reports 46 eyes of 43 consecutive patients with moderate or severe upper eyelid retraction who were recommended for surgery. The period of the study was between October 2016 and October 2019. All cases were evaluated for eyelid position before and at 3, 6, and 12 months after the operation. Successful outcome was defined as "perfect," "acceptable," and "failure". Results The average age was 33.3 years (range, 16-59 years). The average orbital septal flap height was 5.28 ± 0.77 mm. Before surgery, 78.3% had 1 of 3 central upper eyelid retraction (group 1), and 21.7% had 1 of 3 lateral upper eyelid retraction (group 2). During follow-up postoperatively, all eyelid parameters of upper marginal reflex distance, upper scleral show, and palpebral fissure height significantly decreased compared with preoperative values in both groups. The result was considered "perfect" or "acceptable" in 42 eyes (91.3%). However, at 12 months after surgery, of the 36 middle eyelid retraction cases (group 1), 35 (97.2%) showed a successful outcome (perfect or acceptable results), while the success rate in group 2 was 70% (7 of 10 cases), a significant difference (p = 0.008). No severe complications were seen during follow up. Conclusions Orbital septal flap is a safe and reliable procedure for management of upper eyelid retraction of moderate and severe degree.

Purpose Vascular anomalies are a heterogeneous group of disorders that frequently present in the periorbital region. They encompass 2 broad entities: vascular tumors, which possess a proliferative endothelium, and vascular malformations, which are basically localized defects of vascular morphogenesis. The primary goal of this review was to address inaccurate or controversial terminology in the oculoplastic literature concerning orbital and periorbital vascular anomalies and to categorize these lesions in an abridged and simplified hierarchical list that adheres as much as possible to the most recent (2018) iteration for the classification of vascular lesions proposed by the International Society for the Study of Vascular Anomalies (ISSVA). The secondary goal of this review was to review and update information regarding the genetic underpinnings of vascular anomalies and the downstream signaling pathways that are subsequently affected as a result of these genetic errors. Methods A literature review was conducted in PubMed, MEDLINE, PubMed Central, National Center for Biotechnology Information Bookshelf, and Embase for several related keywords including "vascular anomalies, vascular malformations, vascular tumors, and cavernous venous malformation," both with and without adding the keywords "eyelid," "orbital," and "periorbital." In addition, a detailed search was conducted for controversial or obsolete keywords like "cavernous hemangioma," "lymphangioma," and "varices," again in their systemic and orbital/periorbital context. Results Crucial issues in the 2018 ISSVA classification regarding the proper categorization of orbital vascular anomalies, particularly venous lesions, were critically evaluated and revised, and a regional, simplified, and abridged modification of the ISSVA 2018 classification was proposed. Conclusions Interdisciplinary and intradisciplinary dialogue concerning orbital vascular anomalies is seriously compromised due to the lack of a unanimous agreement on terminology and the absence of a unified classification concept system. The authors recommend that oculoplastic surgeons adopt ISSVA terminology whenever technically possible and scientifically sound. However, they also propose modifying the ISSVA 2018 classification specifically to adapt to the peculiarities of vascular anomalies in the periorbital region. At present, the simplified classification proposed here is a preliminary first step towards managing patients with orbital vascular anomalies with greater diagnostic and therapeutic precision, until such time in the future when the entire genetic makeup of orbital vascular anomalies is more completely elucidated. Optimistically, this could pave the way for a more robust classification and the ultimate therapeutic cure.

SUMMARY Patients with aponeurotic blepharoptosis who are treated with external levator advancement may experience complications such as upper eyelid height asymmetry and often require revision surgery. The authors assessed the efficacy of Muller muscle-conjunctival resection in cases with upper eyelid height asymmetry following bilateral external levator advancement. The authors used retrospective analysis of 11 cases between September of 2016 and October of 2018 with eyelid asymmetry following bilateral external levator advancement. Following a positive phenylephrine test, these patients underwent unilateral Muller muscle-conjunctival resection revision surgery to treat the undercorrected eyelid. Preoperative and postoperative marginal reflex distance 1, symmetry outcomes, and clinical outcomes of patients were evaluated after the Muller muscle-conjunctival resection. The average patient age was 54.81 ± 3.95 years (range, 37 to 69 years; median, 56 years); seven patients (63.6 percent) were women. Hering dependency was seen in all patients before the external levator advancement. A total of three patients underwent bilateral external levator advancement simultaneously, and eight patients underwent bilateral external levator advancement sequentially. The phenylephrine test was positive in all patients before the Muller muscle-conjunctival resection. Symmetry outcomes were assessed after the revision surgery as perfect (

BACKGROUND The subperiosteum, supraperiosteum, and intrasuborbicularis oculi fat have been used as planes of dissection for orbital fat transposition in transconjunctival lower blepharoplasty. The steep learning curve due to the anatomic complexity in using any of the 3 planes may deter plastic surgeons from performing the procedure. We present the use of clear anatomical midcheek spaces, the premaxillary and prezygomatic spaces, as the plane for orbital fat transposition in transconjunctival lower blepharoplasty. METHODS We performed a retrospective study of 184 consecutive patients who underwent transconjunctival orbital fat transposition using the midcheek spaces from November 2013 to July 2019. Recorded data included the patient's age, duration of surgery, postoperative complications (chemosis; bleeding; lower eyelid swelling; orbital and/or lower eyelid infection; eye misalignment on primary gaze; binocular diplopia; numbness involving the lower eyelid, cheek, and upper lip; orbicularis oculi paralysis, inferior scleral show, and lower eyelid ectropion), aesthetic result, and patient satisfaction. RESULTS The mean age is 35.48 ± 6.66 years. Significant aesthetic improvement was achieved not only for herniated orbital fat and prominent lid-cheek junction but also for midcheek depression over an average follow-up of 22.41 ± 16.04 months. The patient satisfaction score (98.91%) was high. No major complications occurred. The mean operating time was 46.74 ± 6.67 minutes. CONCLUSIONS The natural midcheek spaces could be used as an ideal plane for orbital fat transposition in transconjunctival lower blepharoplasty. By using the midcheek spaces, transconjunctival orbital fat transposition can become a safe and effective technique without the steep learning curve.

Significance Filamentary keratitis is frequently a recurrent corneal condition characterized by the presence of filaments attached to the cornea. This condition can be challenging to manage because the clinician must treat the underlying cause and filament formation. N-acetylcysteine, a mucolytic agent, should be considered as adjunctive therapy to manage refractory cases. Purpose This case demonstrates the utility of a mucolytic agent, N-acetylcysteine, to treat and manage filamentary keratitis when conventional therapies failed to provide long-term symptomatic relief and reduction of further filament formation. Case report A 70-year-old man with recurrent filamentary keratitis (first occurrence 8 years prior) presented to the clinic with worsening red and painful eyes for 2 days. Prior treatment and management included artificial tears and ointments, punctal plugs, topical corticosteroids, contact lenses, and eyelid hygiene. Slit-lamp examination revealed multiple corneal filaments that were removed with forceps. He was diagnosed with recurrent filamentary keratitis secondary to dry eye disease and treated with preservative-free ophthalmic ointment, oral doxycycline, and 10% N-acetylcysteine ophthalmic solution. The patient had complete resolution of corneal filaments with significant relief of symptoms at 3-week, 5-month, and 10-month follow-up examinations. Conclusions N-acetylcysteine is not commercially available in an ophthalmic solution and must be compounded by a local pharmacist for patient use. Because filamentary keratitis can be challenging to manage because of frequent recurrences, addition of N-acetylcysteine to the treatment regimen should be considered a viable option in refractory cases when other therapies have failed to provide sustained symptomatic relief and resolution of filaments.

PURPOSE OF REVIEW: Dry eye disease (DED) is a multifactorial disease affecting approximately 5–50% of individuals in various populations. Contributors to DED include, but are not limited to, lacrimal gland hypofunction, meibomian gland dysfunction, ocular surface inflammation, and corneal nerve dysfunction. Current DED treatments target some facets of the disease, such as ocular surface inflammation, but not all individuals experience adequate symptom relief. As such, this review focuses on alternative and adjunct approaches that are being explored to target underlying contributors to DED. RECENT FINDINGS: Neuromodulation, stem cell treatments, and oral royal jelly have all been studied in individuals with DED and lacrimal gland hypofunction, with promising results. In individuals with Meibomian gland dysfunction, devices that provide eyelid warming or intense pulsed light therapy may reduce DED symptoms and signs, as may topical Manuka honey. For those with ocular surface inflammation, naturally-derived anti-inflammatory agents may be helpful, with the compound trehalose being farthest along in the process of investigation. Nerve growth factor, blood-derived products, corneal neurotization, and to a lesser degree, fatty acids have been studied in individuals with DED and neurotrophic keratitis (i.e. corneal nerve hyposensitivity). Various adjuvant therapies have been investigated in individuals with DED with neuropathic pain (i.e. corneal nerve hypersensitivity) including nerve blocks, neurostimulation, botulinum toxin, and acupuncture, although study numbers and design are generally weaker than for the other DED sub-types.. SUMMARY: Several alternative and adjunct DED therapies are being investigated that target various aspects of disease. For many, more robust studies are required to assess their sustainability and applicability.

PURPOSE Opioids may be indicated to mitigate pain after oculofacial surgery. The opioid crisis prompted attention to how these medications are dispensed and disposed. This study aims to characterize opioid usage and handling of patients undergoing oculofacial plastic surgery. METHODS Eighty-nine adult patients were surveyed on their opioid usage after undergoing orbital, lacrimal, or eyelid (including esthetic) surgery at a tertiary oculofacial plastic surgery practice. Each patient was prescribed 10 tablets of hydrocodone/acetaminophen 5 mg/325 mg; one tablet taken orally as needed every 6 hours for pain not relieved by acetaminophen. Subset analysis was performed for type of surgery, age, and gender. RESULTS Patients consumed an average of 3 ± 0.4 tablets. In the subsets, the averages were 2.1 ± 0.5 (n = 38) tablets after eyelid surgery, 1.6 ± 0.6 (n = 24) after lacrimal surgery, and 5.6 ± 0.9 (n = 27) after orbital surgery. Greater opioid usage was observed after orbital versus eyelid surgery (p = 0.0007) and orbital versus lacrimal surgery (p = 0.0005) but not eyelid versus lacrimal surgery (p = 0.8604). Forty-six patients (51.7%) used no opioids. Over half (57.3%; n = 51) filled their prescription. Thirty-three patients (37.1%) had unused medications, of which 21 patients did not properly dispose of their medications. The mean age of patients who used opioids was less than the mean age of those who needed no opioids (p = 0.024). There were no gender differences in opioid usage use versus not (p = 0.62). CONCLUSIONS Opioid needs after oculofacial plastic surgeries, especially eyelid and lacrimal, were minimal in this cohort. For most patients, the prescription exceeded needs. Younger age but not gender was associated with opioid use versus not. Most did not properly discard these medications. Quality improvement in both the dispensing and disposal of opioids in oculofacial surgical practice may be warranted.

PURPOSE To determine the effect of chronic topical use of prostaglandin analogs for glaucoma on lower eyelid tension. METHODS A prospective case-control study was performed. Lower eyelid tension was measured in a group of glaucoma patients (73 eyelids) using prostaglandin analogs and a paired control group (87 eyelids). Seven glaucoma patients with unilateral use of prostaglandin analogs had the lower eyelid tension of the exposed side compared with the contralateral eyelid. Eyelid tension was digitally measured in photographs in neutral position and after manual downward traction in the center of the eyelid (modified distraction test). Duration of drug exposition, age, use of other topical medication and other prostaglandin-associated periorbitopathy signs as long eyelashes, eyelid hyperemia, eyelid pigmentation, and deepening of upper eyelid sulcus were recorded for analysis. RESULTS Mean lower eyelid tension in prostaglandin group was significantly higher than in control group: distraction 5.26 mm (SD 1.52) versus 6.80 mm (SD 1.29) (p < 0.001). On the unilateral prostaglandin use intragroup comparison, mean lower eyelid distraction in prostaglandin side was 4.24 mm (SD 1.80) and in control side was 6.79 mm (SD 1.63) (p < 0.012). Beta blocker and carbonic anhydrase inhibitor concomitant use was associated with lower eyelid tension measures in prostaglandin users. Presence of long eyelashes was associated with higher eyelid tension. All other measured variables did not demonstrate interaction with eyelid tension. CONCLUSIONS Chronic topical use of prostaglandin analogs for glaucoma is associated with lower eyelid tightening.

Purpose To investigate the usefulness of the reverse Hughes flap procedure combined with a sandwich graft of an acellular dermal matrix for reconstruction of large full-thickness defects of upper eyelids after cancer excision. Methods Clinical data were obtained from patients who underwent upper eyelid reconstruction using a reverse Hughes flap combined with a sandwich graft of an acellular dermal matrix (AlloDerm) as a tarsal substitute. The tarsoconjunctival flap of the donor lower eyelid was mobilized to reconstruct the posterior lamella, and acellular dermal matrix was grafted onto the tarsoconjunctival flap. A skin-orbicularis muscle flap superior to the defect was advanced to cover the acellular dermal matrix graft, followed by application of lid crease formation sutures to prevent postoperative entropion. The tarsoconjunctival pedicle was divided 3-8 weeks after the surgery. Results Six patients with sebaceous carcinoma were included, and all had ≥70% full-thickness upper eyelid defects after tumor excision. After a median follow-up of 40 months (range 6-62 months), all 6 showed satisfactory functional and cosmetic outcomes. Tumor recurrence, exposure keratopathy, upper eyelid entropion, persistent use of bandage contact lenses, lower eyelid deformity, and dermal matrix-related complications were not observed by the last follow-up. Conclusions Reverse Hughes flap combined with a sandwich graft of an acellular dermal matrix as a tarsal substitute was successful in reconstructing large upper eyelid defects. Acellular dermal matrix graft and lid crease formation sutures enhance marginal stability and prevent postoperative entropion of the reconstructed upper eyelid.

Perineurioma is a rare soft-tissue tumor with characteristic histologic and immunohistochemical features. The diagnosis; however, can be met with certain challenges. A 71-year-old woman presented with an enlarging painless mass in the right lower eyelid-cheek junction. The lesion presented as a raised overhanging trunk-shaped mass. An excisional biopsy and local reconstruction were performed. The overall morphology and immunohistochemical findings were most supportive of a cellular soft-tissue perineurioma, with differential diagnoses including dermatofibroma. To the authors' knowledge, this is the first histopathologically reported case of a superficially occurring soft-tissue perineurioma in the eyelid-cheek junction. The authors discuss the presentation, relevant literature, and controversies associated with this diagnosis.

Background: The reconstruction of the upper eyelid and the periorbital region is a challenge for the surgeon. The aims of this reconstruction are to guarantee protection to the eyeball, maintain the visual field, and restore the function of the eyelid without damaging other anatomical structures. In this study, the authors describe the use of a propeller myocutaneous flap based on the small vertical branches of marginal, peripheral ed superficial arcade, for the reconstruction of the upper eyelid or periorbital region. Materials and methods: The authors enrolled 3 patients (Caucasian), between 2018 and 2019, and subjected to reconstructive surgery with the propeller myocutaneous flap of the periorbital region at the Plastic Surgery Unit of the University of Messina. The vascularization of the flap was demonstrated through an anatomical study conducted on cadavers at the dissection laboratories of the University of Bordeaux 2. Results: The authors have shown that the myocutaneous flap represents a valid alternative for loss of substance coverage and reconstruction of the upper eyelid or periorbital region, allowing the achievement of a good aesthetic and functional result. Follow up: Patients were followed up at 3-6-12 months. No complications were reported (flap retraction, periocular region deformity, donor site morbidity). Furthermore, at the last visit, the scars were almost invisible. Conclusions: The use of the propeller myocutaneous flap of the upper eyelid is a valid reconstructive alternative to the standard techniques described so far for the reconstruction of the periorbital region.

Coccidioidomycosis osteomyelitis involving the orbital bones is exceedingly rare and is often misdiagnosed initially as other inflammatory or infectious conditions. No clear guidelines currently exist regarding appropriate management. The authors present an atypical presentation of disseminated coccidioidomycosis in an immunocompetent child with frontal bone superotemporal orbital rim osteomyelitis and associated periorbital abscess, successfully managed with surgical debridement through an upper eyelid crease incision.

BACKGROUND The tension balance of the upper eyelid following ptosis repair is crucial to a successful postoperative outcome. To improve on existing surgical techniques, the authors developed a new refined frontalis muscle flap suspension (FMFS) for severe ptosis repair and explored the balancing effect between the orbicularis muscle and frontalis muscle following surgery. METHODS Forty-three patients (47 eyes) with a mean age of 6.07 ± 2.55 years old were diagnosed with severe congenital ptosis and underwent refined FMFS with complete orbicularis preservation between January 1, 2010 and December 31, 2017 in the Wenzhou Eye Hospital, Wenzhou, China. The outcomes measured include upper eyelid margin reflex distance (MRD1), degree of lagophthalmos, and cosmetic outcome (lash angle, eyelid contour, and crease). Surgical complications were also recorded. RESULTS The preoperative mean MRD1 was -1.29 ± 0.88 mm and preoperative levator function was 1.87 ± 0.82 mm (ranged from 0 to 3.0 mm). Following surgery, lagophthalmos was observed in all cases in the first week with a mean palpebral fissure height of 1.68 ± 0.40 mm and diminished over 3 months. The MRD1 improved to +3.04 ± 0.68 mm at 6 months following surgery. All cases showed excellent cosmetic outcomes. There were no significant complications. CONCLUSION The refined FMFS is a safe and reliable surgery in treating severe ptosis. The eye-closing power of the intact orbicularis muscle is sufficient at countering the lifting power of the frontalis muscle suspension, achieving a balanced blink mechanism and eyelid closure.

Double-eyelid blepharoplasty, the procedure to create supratarsal crease, has been one of the most popular cosmetic operations in Asia for many years. This study aimed to assess the effectiveness and safety of a surgical procedure using a composite tissue flap for double-eyelid blepharoplasty. A surgical technique was introduced and patients having blepharoplasty with this technique from January 2017 to August 2019 were retrospectively studied. In this technique, a composite tissue flap consisted of the posterior septum and levator aponeurosis was formed and fixed with orbicularis oculi muscle and tarsus. The cosmetic outcomes, patient satisfaction, and complications from the documented medical records were analyzed. Eighty female and 1 male patients had blepharoplasty with the proposed technique and were followed up from 6 months to 42 months. Six patients were found to have mild blepharoptosis. As for cosmetic outcomes, 71patients were graded as good, 7 patients were graded as fair, and only 1 patient was graded as poor. Those patients who were not graded as good had visible scarring, shallow eyelid crease, or asymmetry. The overall patient satisfaction was as high as 95.1%. Mild hematoma formation occurred in 3 patients and no infection or blepharoptosis was observed. One patient complained of asymmetry and 2 patients complained of unilateral crease fading as the complications. The technique is effective to develop durable and natural-looking double eyelids with minimal complications. It could also be an option for mild ptotic patients who ask for double-eyelid blepharoplasty.

Purpose To analyze the tear dynamics during blinking by measuring the inner pressure of the upper lacrimal drainage system. Methods This observational study involved 11 healthy bi- or tricenarian volunteers. Direct manometry was performed using a fiber optic pressure sensor inserted into the conjunctival sac, upper/lower canaliculus (5 mm from punctum), and inferior lacrimal sac (15 mm from punctum) during both involuntary and intentional tight blinking. Pressure was measured 200 times/second during 3 separate blinks and then chronologically analyzed. Results In all subjects of all locations during both types of blinking, the inner pressures during the stationary eyelid closing/opening were positive/approximately zero, while a positive/negative pressure spike was observed during the eyelid closing/opening movement. The averages of the maximum pressure in the spike during the intentional tight blinking (tPmax: mm Hg) in the conjunctival sac, upper/lower canaliculus, and lacrimal sac were 8.00, 12.39/12.93, and 10.59, respectively, while for the minimum (tPmin: mm Hg), the pressures were -3.18, -3.91/-3.43, and -3.31, respectively. The tPmax and tPmin in the lacrimal duct were positively correlated with that of the conjunctival sac, which suggested synchronism of the drainage system. However, the tPmax in the canaliculus was significantly higher than that of the conjunctival sac, which suggested that tears do not flow from the conjunctival sac into the lacrimal duct during eyelid closure. Conclusions The upper lacrimal drainage system functions as one united lumen in the lacrimal pump. The positive /negative pressure spike is essential for the lacrimal pump to efficiently eject/aspirate the tear from the lacrimal/conjunctival sac.

Purpose The purpose of the report was to describe the first successful tarsal fracture surgery in a 1-year-old boy diagnosed with cicatricial ocular pemphigoid whose visual and psychomotor development were notably limited. Methods We present the case of a 1-year-old boy diagnosed with mucous membrane pemphigoid by biopsy who was treated with rituximab (375 mg/m2 intravenous infusion at 2-week interval administered twice) and stable with oral dapsone (2 mg·kg-1·d-1). His eyelid cicatricial entropion and trichiasis in both eyes prevented him from opening his eyes, impeding visual development. After 1 year of clinical stability, we performed a tarsal fracture procedure in both eyes to restore eyelid anatomy and functionality, with the aim to prevent an inflammatory reaction, administrating intravenous dexamethasone before and after surgery. Results The intervention was successfully performed without postoperative complications. Excellent anatomic and functional results allowed him to develop normally in his daily life the first week after surgery. He is currently taking oral dapsone (2 mg·kg-1·d-1) as a maintenance treatment to stop the progression of the disease. Conclusions Tarsal fracture surgery may be considered part of the treatment in pediatric patients with stable ocular cicatricial pemphigoid presenting with severe entropion and trichiasis.

Purpose To describe a novel surgical technique for implanting eyelid weights via a sutureless transconjunctival approach. In comparison to the traditional supratarsal crease approach, this technique does not involve any external incisions or suture placement. The procedure can reduce surgical time and complications associated with the traditional external approach. Methods This case series includes 13 patients who underwent eyelid weight placement via the transconjunctival approach for paralytic lagophthalmos secondary to facial nerve paralysis (12 patients had unilateral paralysis and 1 patient had bilateral) with a total of 14 eyelid weights placed. The procedures were performed at an outpatient office-based surgical center. All procedures were performed or supervised by the same surgeon. Patients were followed for an average 6-month postoperative period for postoperative complications. Results The sutureless transconjunctival approach to eyelid weight insertion was successful in achieving the desired functional and aesthetic outcomes. Patients undergoing this technique avoided the discomfort of postoperative suture removal. All patients achieved comparable outcomes postoperatively. There were no complications reported across the 13 patients throughout the 6-month postoperative period. Conclusions This case series demonstrates that the transconjunctival approach for metal eyelid weight insertion is practical, relatively easy to perform, and associated with functional outcomes that are comparable to those achieved with the traditional approach, however, without external incision or placement of sutures.

A newborn male with cat eye syndrome presented with progressively worsening bilateral upper eyelid imbrication, floppy eyelids, and ptosis. Despite conservative management, he remained unable to open his eyelids. Surgical correction was planned to prevent bilateral sensory deprivation amblyopia and was delayed until 5 months of age due to systemic health concerns. Bilateral full-thickness wedge excision and frontalis suspension with silicone rods in a double rhomboid fashion was performed. Postoperatively, the patient demonstrated spontaneous eyelid opening, resolution of spastic eversion of the upper eyelids, and adequate eyelid closure. The authors present the first case of concurrent floppy eyelid syndrome and upper eyelid imbrication reported in a cat eye syndrome patient.

INTRODUCTION The aim of the present study is to examine the effect of local administration of tranexamic acid (TXA) through lateral osteotomy line on postoperative periorbital edema and ecchymosis. MATERIALMETHOD Thirty patients underwent open technical septorhinoplasty were included. Before lateral osteotomies, the surgeon opened narrow subperiosteal tunnels on the both sides. After lateral osteotomies, the surgeon irrigated TXA into the right tunnel with the broken tip of the injection and the same amount of saline into the left tunnel. The patient's photographs were taken on the first, third, and seventh postoperative days. Periorbital edema and ecchymoses were evaluated by the blinded author. The statistical differences between the 2 sides were analyzed. RESULTS Lower Eyelid Edema values were significantly lower in the TXA(+) group than the TXA(-) group on the third day (P = 0.001). There was no statistically significant difference between the sides in terms of lower eyelid edema values on the first and seventh days (P = 0.065, P = 0.317). Upper and lower eyelid ecchymosis values were significantly lower in TXA(+) group than TXA(-) group on the first, third, and seventh days (P

Purpose To describe postoperative management following ablative carbon dioxide laser resurfacing of the lower eyelids. Methods A retrospective review of patients who consecutively underwent bilateral lower eyelid ablative carbon dioxide laser resurfacing by a single experienced oculoplastic surgeon over a 6-year period was conducted. Patient satisfaction, aesthetic outcomes, and postoperative complications were evaluated as adjunctive or monotherapy. Results Among 424 patients included in the study, most were female (n = 356, 84.0%) and Caucasian (n = 404, 95.3%), with Fitzpatrick skin types II-III (n = 381, 89.9%). Mean age was 62.8 years (standard deviation: 9.7 years). Most (n = 324, 76.4%) underwent fractional ablative carbon dioxide laser resurfacing of the lower eyelids, whereas 91 (21.5%) received traditional laser resurfacing and 9 (2.1%) had both fractional and traditional laser resurfacing during the same session. At the time of lower eyelid laser resurfacing, most patients also underwent concurrent procedures, including upper (n = 321, 75.7%) and lower blepharoplasty (n = 348, 82.1%); a small proportion of patients (n = 39, 9.2%) did not undergo any concurrent surgical procedure. In addition to ablative laser resurfacing of the lower eyelids, 25 (5.9%) had upper eyelid laser resurfacing, 60 (14.2%) had full-face laser resurfacing, 55 (13.0%) had neck laser resurfacing, and 42 (9.9%) had additional treatment of solar lentigines or dyschromias on the face. Median follow-up duration was 3.9 months (interquartile range: 2.0-11.0 months). In the immediate postoperative period, 22 patients (5.2%) developed contact dermatitis from topical antibiotic eye drops and/or ointment prescribed postblepharoplasty. Postinflammatory hyperpigmentation was observed in 40 patients (9.4%) despite topical prophylaxis; all were eventually successfully treated with a combination of topical nonprescription and prescription creams and/or oral tranexamic acid. A localized herpetic outbreak occurred in 3 (0.7%) who underwent full-face laser resurfacing and 1 (0.2%) who underwent periocular laser resurfacing only; all were successfully treated with oral antiviral therapy. Two (0.5%) developed culture-proven atypical mycobacterial infection of the resurfaced lower eyelid skin and were treated with combination antibiotic therapy for several months until resolution. A small scar was noted in 4 patients (0.9%), which resolved after local corticosteroid injections. No patient developed persistent scarring or ectropion. Patient satisfaction was overall high, with 363 (85.6%) very satisfied and 48 (11.3%) satisfied with the aesthetic outcome of lower eyelid laser resurfacing. Conclusions Ablative carbon dioxide laser resurfacing of the lower eyelids can be a useful tool in the armamentarium of the experienced oculoplastic surgeon, with excellent aesthetic results, high patient satisfaction, and low complication rates as adjunctive or monotherapy. Proper and timely management of postoperative complications is essential to maximizing successful cosmetic outcomes.

Background Although Park's "orbicularis-levator fixation technique" has been widely used as a mature double-eyelid surgery in China recently. Shortcomings related to this method cannot be ignored. Thus, a reverse orbicularis-tarsus fixation technique in double-eyelid blepharoplasty has now been devised. The method is to create a physiological double-eyelid fold based on the formation mechanism of double-eyelid creases. Methods A retrospective study of 112 Chinese patients who underwent double-eyelid surgery between October 2017 and September 2019 was undertaken through a review of medical records. All these patients underwent a reverse tarsus and orbicularis oculi muscle fixation technique, with postoperative follow-up ranging from 6 months to 2 years. Postoperative outcomes were reviewed, evaluated, and analyzed. Results Altogether, 112 patients who underwent the double-eyelid surgery were reviewed. Among them, the results were judged as excellent in 104 cases (92.9%), good in 4 cases (3.6%), fair in 3 cases (2.7%), and poor in 1 case (0.8%). Clinical effectiveness was satisfactory in most of the patients (104/112, 92.9%). Only 5 patients (4.5%) expressed subjective dissatisfaction with postoperative outcomes; of these, 3 patients complained of eyelids asymmetry (2.7%). Two patients complained of eyelids scar formation (1.7%); Whereas surgical revision was required in only 1 patient (0.8%). Conclusions The reverse orbicularis-tarsus fixation technique for upper eyelid blepharoplasty is safe and effective, with better biomechanics and a satisfying aesthetic outcome. Therefore, this provides an alternative option in Chinese double-eyelid surgery.Level of Evidence: Level IV, case studies.

BACKGROUND Perceived pain during local anesthesia injections can be effected by the injection sequence. OBJECTIVE We sought to compare pain levels during local anesthesia injections during upper lid blepharoplasty (ULB) using 2 surgical sequences. MATERIALS AND METHODS We conducted a prospective, randomized clinical trial. Patients with ULB were randomized to either have local anesthesia injection followed by ULB in the right eyelid and then in the left (Group A) or to have local anesthesia injection to both eyelids followed by ULB on both eyelids (Group B). Pain was assessed using a visual analog scale (VAS) for pain score of 0 to 10. RESULTS Forty patients were included and randomized. The mean VAS score in Group A was 2.60 ± 1.84 and 3.30 ± 1.62 (right and left, respectively, p value = .035). The mean VAS score in Group B was 2.55 ± 1.63 and 2.80 ± 1.67 (right and left eyelids, respectively, p value = .258). No intergroup difference in pain was found. CONCLUSION Patients having sequential anesthesia during ULB perceived more pain on injection to the second eyelid, whereas patients having local anesthesia followed by ULB perceived the same amount of pain in both eyes. Pain levels in both groups were similar. Local anesthesia injections in both groups were well tolerated.

Significance This report shares the long-term outcomes of an uncommon use of prosthetic replacement of the ocular surface ecosystem (PROSE) treatment and scleral lenses in the treatment for patients with ptosis who are not surgical candidates. Purpose This study aimed to describe a case of pediatric traumatic lid ptosis and follow-up during an 8-year period with PROSE treatment. Case report A 7-year-old Honduran girl presented with a history of severe cranial, facial, and ocular trauma as a result of a motor vehicle accident. Significant ptosis with left-sided facial paralysis and irregular astigmatism significantly reduced the patient's visual function in the left eye. She was evaluated and treated with a scleral prosthetic device in the left eye to improve vision, the ocular surface, and overall function for activities of daily living. After 8 years of PROSE treatment, acuity in the left eye remained stable at 20/25. The corneal health remained stable throughout this period, without complications of corneal neovascularization or corneal edema. Conclusions Prosthetic replacement of the ocular surface ecosystem treatment provided support of the ocular surface and mechanical left upper eyelid lift in a traumatic eyelid ptosis, ultimately providing improved visual function during an extensive 8-year period in a pediatric patient. Further studies are needed to evaluate the applicability of this approach in broader ptosis cases.

Purpose To describe the frequency of blepharoptosis and factors affecting it after the pars plana vitrectomy (PPV) procedure. Methods In a prospective study, patients were recruited consecutively from October 2016 to June 2018. Upper eyelid margin reflex distance 1 and 2 (MRD1 and 2), upper eyelid crease height, and levator function were measured before, 1 and at least 6 months after surgery by the same investigator. Clinical and Clinically significant ptosis were defined as ≥0.5 and ≥2 mm drop of MRD1. Result There were 60 eyes from 57 patients. The majority of surgeries were performed by the fellows (63.3%, 38/60) and under general anesthesia (95.0%, 57/60). Clinical and clinically significant ptosis following PPV were 47.2% (25/53) and 11.3% (6/53) at the last follow up (at least 6 months), respectively. MRD2 (p = 0.389) and eyelid crease height (p = 0.057) did not significantly change. Surgeons' level, time of the procedure and other variables were not significantly impacting the frequencies. Conclusion Persistent clinically significant ptosis was observed in 11% of patients undergoing PPV. No variable was significantly associated with persistent postoperative ptosis after PPV.

We report a patient who underwent secondary reconstruction for facial paralysis involving 2 regions of augmentation and 3 facial reanimations using a neurovascular latissimus dorsi (LD) chimeric flap.A 53-year-old man underwent mid-skull base surgery for a chondrosarcoma at the temporomandibular joint and primary reconstruction using a free anterolateral thigh flap. At 28 months after surgery, he showed temporal and buccal depression and incomplete facial paralysis. We planned 1-stage reconstruction using a neurovascular LD chimeric flap, which was divided into dual compounds of the neurovascular muscle with soft tissue along the descending and transverse bifurcation of the thoracodorsal neurovascular bundle. We added adipose tissue to the muscle belly of the transverse branch using microperforators. We cut the transverse nerve 2.7 cm from the hilus and about 5 cm from the bifurcation, enabling the proximal stump of the transverse branch to be sutured to the ipsilateral buccal branch and function as a cross-face nerve graft. The transverse branch compound was placed on the temporal region and its neural pedicle was sutured to the zygomatic branch. The descending branch compound was placed in the buccal region and sutured to the contralateral buccal branch.At 58 months after surgery, good contour remained, and smiling was voluntary and natural. On needle electromyography, the zygomatic major muscle and the muscle transferred to the buccal region showed good contraction, and the muscle transferred to the temporal region provided tonus to the lower eyelid. The versatility of the neurovascular chimeric flap facilitated multiple augmentations and 3 reanimations.

Purpose Blepharitis, simply defined as eyelid inflammation, is one of the common ocular conditions associated with discomfort and irritation. Because blepharitis causes meibomian gland dysfunction and dry eye, this study aimed to confirm the effect of photobiomodulation (PBM) on blepharitis. Methods A total of 20 rats were randomly assigned to 4 equal groups, including control, blepharitis, PBM, and eye drop. Blepharitis was induced in rats by injecting complete Freund's adjuvant in the eyelid margins. PBM intervention was given every 3 days after blepharitis induction. Clinical signs including tear volume, tear breakup time (TBUT), meibomian gland swelling, fluorescein, telangiectasia, and meibomian gland secretion scores were measured every week, and the rats were killed for histological analysis after 4 weeks. Immunohistochemistry was performed to compare the level of inflammatory cytokines, interleukin-1β and tumor necrosis factor-α, and terminal deoxynucleotidyl transferase dUTP nick end labeling staining on retina was performed to observe any retinal damage. Results Tear volume and TBUT increased with PBM intervention, and with improved eyelid swelling, corneal staining, telangiectasia, and meibomian gland secretion scores increased. Hematoxylin and eosin staining showed no structural abnormalities of meibomian gland caused by blepharitis induction. Immunohistochemistry revealed that the levels of inflammatory cytokines interleukin-1β and tumor necrosis factor-α were lowered with PBM treatment in both eyelid and conjunctiva. Terminal deoxynucleotidyl transferase dUTP nick end labeling staining showed no retinal damage. Conclusions Laser PBM at 808 nm was effective in alleviating ocular signs and controlling inflammation in blepharitis rat model. The in vivo results suggest that PBM has the potential to be used in treating blepharitis patients.

PURPOSE To evaluate periorbital volume changes, using quantitative photogrammetric stereoimaging, after bony orbital decompression for thyroid eye disease (TED) and compare this to changes in Hertel exophthalmometry. Tissue volumes of the upper and lower eyelids were also assessed independently. DESIGN Prospective, nonrandomized, nonconsecutive series of patients. SUBJECTS Adults with inactive TED who had elected to undergo bony orbital decompression at Moorfields Eye Hospital between 2015 and 2017. METHODS With their eyes gently closed, patients with inactive TED underwent imaging using the VECTRA M3 system (Canfields Imaging, Fairfield, NJ), both before and at least 3 months after orbital decompression. Proptosis was assessed by Hertel exophthalmometry. Using the manufacturer's software, changes in periorbital volumes between the preoperative and postoperative images were calculated for the upper and lower eyelids. The Pearson product-moment correlation coefficient was used to assess the linear relationship between changes in periorbital volume and exophthalmometry. MAIN OUTCOME MEASURES Change in stereoimaging volumes of the upper and lower eyelids, and clinical proptosis as measured with Hertel exophthalmometry. RESULTS Thirty-three patients (11 males; 33%) underwent lateral decompression (39 orbits in 26 patients), lateral decompression with complete ethmoidectomy (3 orbits in 3 patients), combined decompression of lateral wall, medial wall, and medial half of floor (10 orbits in 6 patients), or bilateral lateral, medial, and complete floor decompression (1 patient). The corresponding average volumetric changes were 1.74 ml (median 1.64; range 0.39-3.73 ml), 3.38 ml (median 3.38, range 1.89-4.88 ml), 4.05 ml (median 3.53, range 1.72-6.43 ml), and 4.52 ml (range 4.36-4.68 ml), respectively. Similarly, the average reduction in proptosis was 3.6 mm (median 3; range 1.5-7 mm), 5.3 mm (median 5; range 5-6 mm), 7.4 mm (7.5; range 6-9 mm), and 9 mm (range 8-10 mm). Periorbital volume changes were related to the reduction in exophthalmometry (r = 0.713, p < 0.0001), and reduction of lower eyelid volume did not increase further with more than two-wall decompression. CONCLUSION Graded orbital decompression reduces both proptosis and the upper and lower eyelid tissue volumes, the eyelid changes being likely to influence decisions about future restorative eyelid surgery. The significant changes in eyelid profiles underlines the established principle of thyroid periocular rehabilitation, namely decompression, then strabismus surgery, and finally eyelid surgery.

Therapeutic contact lenses (TCLs) are often used in the management of a wide variety of corneal and ocular surface diseases (OSDs). Indications of TCL include pain relief, enhancing corneal healing, corneal sealing, corneal protection, and drug delivery. For painful corneal diseases such as bullous keratopathy, epidermolysis bullosa, and epithelial abrasions/erosions, bandage contact lenses (BCLs) provide symptomatic relief. Postoperatively in photorefractive keratectomy or laser epithelial keratomileusis, BCLs also alleviate pain. In severe OSDs such as severe dry eye, Stevens-Johnson syndrome/toxic epidermal necrolysis, gas-permeable scleral contact lenses are often used to enhance corneal healing. BCLs are used post-keratoplasty, post-trabeculectomy, and post-amniotic membrane transplantation to enhance healing. BCLs, with or without glue adhesives, are used to seal small corneal perforations and sometimes also used as bridging treatment before penetrating keratoplasty in larger corneal perforations. In patients with eyelid conditions such as trichiasis, ptosis, and tarsal scarring, BCLs are also effective in forming a mechanical barrier to protect the cornea. A relatively new use for TCLs is in ocular drug delivery where TCLs are used to maintain therapeutic concentrations of medication on the ocular surface. Contraindications of the use of TCLs include infective keratitis, corneal anesthesia, and significant exposure keratopathy with inadequate eyelid position or movement. Complications of TCL include infective keratitis, corneal hypoxia and associated complications, corneal allergies and inflammation, and poor lens fit. Overall, TCLs are effective in the treatment of corneal and OSDs but contraindications and complications must be considered.

Purpose: To evaluate the prevalence of dry eye and meibomian gland dysfunction in patients with scleroderma. Methods: A total of 32 patients with scleroderma (study group) and 31 healthy subjects (control group) were enrolled. Besides routine ophthalmologic evaluation, Schirmer 1 test, tear break-up time, tear osmolarity, ocular surface staining with fluorescein (Oxford score), and Ocular Surface Disease Index (OSDI) score, meibomian gland dysfunction evaluation (foamy tears, telangiectasia of the eyelid, eyelid contour abnormalities, and meibomian plugs), and meibography were performed. Results: Sixty-four eyes of 32 patients with scleroderma and 62 eyes of 31 healthy individuals were evaluated. Mean ages of the study group was 48.34 +/- 9.73 years (21-62 years) and of the control group was 45.84 +/- 4.42 years (38-54 years) (P = 0.067). Mean duration of systemic sclerosis or scleroderma in study group was 9.78 +/- 7.40 years (1-30 years). Mean tear break-up time was shorter in study group than that in the control group (P < 0.0005). No statistical differences were detected for osmolarity, OSDI score, and Schirmer 1 values between groups (P = 0.051, P = 0.053, and P = 0.358, respectively). The prevalence of grade 1 and higher Oxford score was higher in the study group (P < 0.0005). Upper meiboscores of grade 1 and higher were found to be more common in the study group than those in the control group (P = 0.036). The presence of foamy tears and telangiectasia of the eyelids were significantly higher in the study group (P = 0.002 and P = 0.002, respectively). OSDI score was the only significantly correlated data with disease duration (Spearman rho coefficient = 0.396, P = 0.001). Conclusions: Evaporative type dry eye is more common in patients with scleroderma than the healthy population., Ege University Scientific Research Projects Coordination Unit [2017-TIP-041], Supported by Ege University Scientific Research Projects Coordination Unit (Project Number: 2017-TIP-041).

The intricate and delicate structure of the periorbital region, particularly in pediatric patients, presents challenges to eyelid reconstruction. Much like the more common lower eyelid ectropion, upper eyelid ectropion can result from lack of tissue, scar contracture, or over-resection as in blepharoplasty. In burns and trauma, the cause of cicatricial ectropion is typically direct scar contracture from injuries to the eyelid. However, in some cases, extrinsic wounds involving contracture to the forehead or eyebrow can result in upper eyelid cicatricial ectropion. Direct reconstruction and skin grafting of the eyelid present complex challenges, especially in the acute inflammatory phase of traumatic injury and burn care. Furthermore, in many of these cases the periorbital and lamellae anatomy is preserved, but rather severely displaced due to scar contracture forces. The authors discuss our experience with treatment of extrinsic upper eyelid cicatricial ectropion in a series of 4 pediatric patients with burns or trauma to the forehead and periorbital regions. In all 4 cases, the antegrade foreheadplasty procedure helped to provide globe coverage, while avoiding skin matching difficulties and the intrinsic risks of operating on the eyelid during the acute phase of recovery. There is currently very limited data for the use of this technique to correct such defects. With this study, the authors hope to establish the antegrade foreheadplasty as a reconstructive option for a select patient population.

Astigmatism causes deterioration of the retinal image and affects vision quality. Maintenance and improvement of visual function requires an understanding of the prevalence, age-related changes, and mechanisms of astigmatism. In this article, we discuss the findings of studies that investigated astigmatism. Some of these studies showed that the prevalence of high degrees of astigmatism in childhood typically decreases with emmetropization. With-the-rule astigmatism occurs most commonly in young adults. With age, the prevalence of astigmatism increases, and the axis shifts from a predominance of with-the-rule astigmatism to a predominance of against-the-rule astigmatism. This age-related change is caused by alterations in corneal curvature. Although the cause of this change is not fully understood, alterations in the position and tension of the eyelid, corneal stromal collagen fibrils, Descemet membrane, and extraocular muscles may influence the shape of the cornea. Furthermore, genetic factors may contribute to the development of astigmatism. Technological advances in ophthalmology are expected to improve our understanding of the etiology of astigmatism and enable the maintenance of quality of vision.

Introduction Plexiform neurofibroma with neurofibromatosis type 1 (NF1) or Von Recklinghausen's disease is a rare entity and occurs in approximately 5–15% patients. These are slow growing, painless and locally infiltrating tumors. The pattern of inheritance is autosomal dominant and its penetrance is almost complete by 5 years of age. Presentation of case We hereby report a case of 13 years old boy visited presenting with swelling of right eyelid and forehead. After surgical removal, the tissue was sent for histopathological evaluation. Microscopy revealed an unencapsulated tumor mass comprising of well organized mixture of multiple nerve bundles with interlacing neural tissue in background of spindle shaped cells along with myxoid areas and numerous blood vessels. Discussion The NF1 gene responsible for the disease is located on chromosome 17 at locus 17q11.2 that codes for the protein neurofibromin. The frequency of neomutations is particularly high and almost half of the cases are sporadic. NF1 is characterized by a wide variability of clinical expressions, even within a given family. Majority of patients can be diagnosed only after thorough physical examination. Conclusion The wide variation of the clinical expression, the tumor risk and the totally unpredictable evolution of the disease impose regular monitoring of NF1 patients. This surveillance is mainly clinical and has to be adapted to the patient's age in order to assure early management of complications., Highlights • Plexiform neurofibroma with neurofibromatosis type 1 is a rare entity. • The presentation of patients with NF-1 is extremely variable. • Early diagnosis is crucial for patient to prevent further complications of the disease. • Psychological counseling and long term follow up is mandatory to improve quality of life.

Objectives To investigate the presence of Demodex mites on the eyelashes of a Japanese population and to explore its associations with subjective ocular symptoms and clinical ocular surface signs, including lid margin findings and fluorescein breakup time (FBUT). Methods Sixty-three Japanese Tokyo-based volunteers were examined (24 men and 39 women; mean±SD of age, 50.6±15.8 years). Eyelash sampling was performed by epilating three lashes from the center of the right upper eyelid. Eyelashes were tested for Demodex mites with a light microscope. The subjects completed questionnaires to assess subjective symptoms and risk factors for dry eye disease (DED) and underwent general examinations for DED, including FBUT and cornea-conjunctival staining with fluorescein. Meibomian gland function was also investigated in lid margin findings, vascularity and mucocutaneous junction movement, lid irregularity, plugging, pouting, and meibum secretion grade scores. Results Demodex mites were found in 20.6% (13/63) of the volunteers. Lid margin vascularity and meibum grades in the upper eyelid margins were significantly associated with the presence of Demodex mites. However, there were no significant differences in the diagnosis of meibomian gland dysfunction, FBUT, or ocular surface discomfort between the subjects with or without Demodex mites. Conclusions Demodex mites are not rare in the cilia of a Japanese population. Lid margin vascularity and lower meibum quality may be associated with the presence of Demodex mites.

Involutional ectropion is a disease in which the eyelids are everted outwards, and because the eyelids move away from the eyeballs, the ocular surface and conjunctiva are exposed causing inflammation, pain, photophobia, foreign body sensation, epiphora, and blurred vision. It is thought to be caused by horizontal and vertical laxity. Various surgical methods have reportedly been used to correct involutional ectropion. Shortening the lower eyelid retractor (LER) is an indispensable surgical operation for medial ectropion. When the LER is shortened, it is usually fixed to the lower edge of the tarsal plate. Herein we describe a new type of surgery that has now been performed on 6 eyes in 4 patients. The procedure involves separating the conjunctiva from the tarsal plate, inserting the LER between the conjunctiva and the tarsal plate, and then fixing it to the back of the tarsal plate. In all 6 eyes, the lower eyelid now contacts the eyeball, and morphological improvements were achieved. This new surgical method is a useful way to raise the tarsal plate.

Purpose To evaluate the efficacy and safety of a bilayer dermal regenerative matrix for primary or complex/recurrent eyelid retraction. Methods Retrospective review of patients undergoing eyelid retraction repair using the bilayer dermal regenerative matrix from 2005 to 2019. Nineteen eyelid surgeries from 15 patients were identified. Collected data included patient demographics, symptoms, preoperative/postoperative lower eyelid position, inferior scleral show, lagophthalmos, etiology of retraction, history of prior retraction surgeries, major/minor complications, and follow-up duration (minimum 6 months). Postoperative measurements were taken at a minimum of 1 week, 3-6 weeks, 2-4 months, and 6 months. Results Postoperatively, 90% of cases had good improvement of lower eyelid retraction (defined as 1 mm or less below the inferior limbus). Postoperative elevation of the lower eyelid ranged 1-3.5 mm compared with preoperative measurements. When used in the upper eyelid for conjunctival scarring, the implant improved the superior fornix depth. Complications were minimal and included transient conjunctival injection, eyelid edema, and foreign body sensation. No patients requested early removal of the silicone layer due to ocular pain. Conclusions The bilayer dermal regeneration matrix template may be considered a reasonable alternative to other spacers to reduce the vertical palpebral fissure and eyelid malposition in primary, complex, or recurrent cases. It also worked well for first-line correction of thyroid retraction, which tend to be more challenging due to globe proptosis. Suboptimal results may have occurred due to active cicatrizing conjunctival disease, or residual negative vector of the cheek and orbit. High cost may be a consideration, and the bilayer dermal regeneration matrix template was not studied directly against hard palate and other spacer materials.

Background Despite the recent advances in the treatment of vitiligo, results are still largely unsatisfactory and many patients show either weak or no response to treatment. Few clinical trials have investigated the use of trichloroacetic acid (TCA) to induce repigmentation in stable vitiligo. Objective To evaluate the efficacy and safety of TCA, in different concentrations, for the treatment of stable localized vitiligo. Methods The study included 100 patients with acral/nonacral stable vitiligo. Trichloroacetic acid was applied, as a monotherapy, to the vitiliginous patches at different concentrations according to the treated site every 2 weeks until complete repigmentation or for a maximum of 6 treatment sessions. Follow-up was done every month for 6 months to detect any recurrence. Results Eyelid vitiligo showed the highest response to TCA treatment (excellent response in 80% of cases), followed by the face, trunk, and extremities. Lower response rates were noticed in the hands and feet vitiligo. Adverse effects were transient and insignificant in few patients. Conclusion Trichloroacetic acid seems to be a potential, cost-effective, well-tolerated therapeutic option for the treatment of vitiligo in the adults and pediatric populations.

In cosmetic surgery, knowledge of the average dimensions of periorbital features based on gender and ethnicity is essential to improve the patient appearance and maintain the ethnicity. The aim the study was to establish gender-specific periorbital anthropometric and anthroposcopic data for Indian Americans (IA) and to assess the statistically ethnic differences by comparing with published data of Malaysian Indians (MI). Evaluation of periorbital features was done on the standardized frontal photographs of 400 IA, aged 18 to 26 years. The measured values were evaluated by an independent t-test. Sexual dimorphism was found in all 15 measurements. The eyebrow height, combined height of the orbit and eyebrow, eyebrow apex inclination, apex to lateral canthus distance, medial end of brow to medial canthus distance, lateral end of brow to lateral canthus distance; pretarsal skin height, palpebral fissure height, palpebral fissure inclination (PFI), and medial canthus tilt were significantly greater in female than the males. In males, eyebrow apex hairline distance, apex to lateral limbus distance, eyebrow apex angle (EAA), lower eyelid height, and interpupillary distance was significantly greater than the females. Significant ethnic difference was found between IA and MI for eyebrow height, apex to lateral limbus distance, EAA, palpebral fissure height, and PFI in male group. In female group, EAA, medial canthus tilt, and PFI were significantly greater in MI. Four types of epicanthus were observed and the brow apex between lateral limbus and lateral canthus was the most common position. The generated normative data may be useful during diagnosis and treatment planning.

Objectives Three prior studies (2008, 2011, 2018) histopathologically compared the eyelid specimens of patients with dermatochalasis (DC, undergoing blepharoplasty) with a control group and proposed that DC may begin with subclinical inflammation leading to elastolysis and lymphostasis. With growing number of younger patients consulting for blepharoplasty, the unanswered question is whether histopathologic changes of DC differ between the younger and the older. Patients and methods In this prospective case series, 20 right upper eyelid skin of 20 nonsmoker, class 3 Fitzpatrik skin type women (30-68 years old) were histopathologically examined. Patients were divided into 2 age groups of 50 years or older and older than 50 years. Upper eyelid skin was preoperatively marked, intraoperatively removed, postoperatively divided into 3 sections: lateral (lateral limbus to lateral canthus), central (between medial and lateral limbi), and medial (medial limbus to medial canthus), and separately (totally 60 specimens) sent for histopathological examination. A masked pathologist recorded skin thickness in all specimens (60) as well as lymphatic vessels diameter and density, elastic fiber density, macrophage number, collagen intrafibril edema, and depth of collagen stromal bed in central sections (20 specimens). Results There were 10 patients at each age group. Histopathological measurements were not significantly different between the 2 age groups except mean lymphatic vessel diameter (P = 0.034) that was larger in the second group (>50 years). A significant positive correlation was also observed between the age and lymphatic vessel diameter (rs = 0.3, P = 0.009). Conclusions Lymphangiectasia progresses significantly by age. Histopathological characteristics of DC are the same in the 2 age groups.

Purpose To determine whether reconstruction of lower eyelid defects involving the eyelid margin with a free tarsal graft and an overlying free skin graft, without retention or provision of any vascular support, would yield acceptable functional and cosmetic results. Methods We present here a clinical series of 4 patients treated between April 2019 and September 2019 who underwent reconstruction of large postcarcinoma excision, eyelid-margin-inclusive eyelid defects. Surgery was performed by the same surgeon (J.G.B.) at the Westchester Medical Center, Department of Ophthalmology and Dobbs Ferry Hospital in New York. Without retaining a conjunctival pedicle (modified Hughes procedure), and without a myocutaneous or other vascularized flap, the lower eyelids were reconstructed with a free tarsal graft and a separate overlying free skin graft. The primary outcomes measured were eyelid apposition to the globe, margin reflex distance 2 at least 6 months postoperatively, ocular surface integrity, and patient comfort and patient satisfaction with the procedure. Results The patients included in the clinical series ranged in age from 73 to 82, 3 were men and 1 women. Each had recent Moh's excision of carcinoma (3 basal; 1 squamous) resulting in large tissue defects of the lower eyelids. All carcinomas were T1N0M0. The mean postoperative margin reflex distance 2 of the reconstructed eyelids was 5.5 mm, range 5-7.5 mm. Two of the 4 patients underwent a secondary revision within 2-3 weeks following initial reconstruction for lateral ectropion or dehiscence. All eyelids were well-opposed to the globes after revision (except for the nasal eyelid in patient number 2 who had a preexisting ectropion from prior carcinoma excision in the same eyelid). Functional and esthetic results were on par with those of the modified Hughes procedure. All 4 patients were pleased that they had chosen to undergo the procedure being discussed. Conclusion In this clinical series of 4 patients, reconstruction of lower eyelid defects with a free tarsal graft and overlying free skin graft resulted in an acceptable functional and esthetic lower eyelid suggesting that retention of or provision of vascular support in either the anterior or posterior lamella may not be necessary.
