PurposeMethodsResultsConclusionsThe aim of this retrospective case review is to present a novel surgical technique used in the treatment of recalcitrant lower eyelid retraction.This study was performed as a retrospective case review of 4 patients who have failed standard conservative surgical interventions for lower eyelid retraction repair. 3 patients developed lower eyelid retraction following surgical intervention for orbital trauma and 1 patient developed lower eyelid retraction in the setting of granulomatosis with polyangiitis. The surgical technique was identical in each patient and performed by an oculofacial plastic surgeon, sometimes together with an oral and maxillofacial surgeon. Follow-up results for all patients were assessed at 1 week, 1 month, and 3 months.All four patients demonstrated initial improvement in lower eyelid position, fullness, and height. A common finding was mild lateral postoperative entropion, which was easily overcome with an upper eyelid tarsoconjunctival flap. There were no surgical complications sustained in any of the cases.This retrospective case review provides a novel surgical option for the correction of recalcitrant lower eyelid retraction. The excellent vascularity provided by this flap, location, and easy access support its use. A prospective study comparing alternative solutions would be useful in comparing the buccal fat pad vascularized pedicle to alternative methods used to correct refractory and cicatricial lower eyelid retraction.

This study aimed to examine the changes in lower eyelid position after blepharoptosis surgery and the factors that influence the outcome. We conducted a retrospective study of 155 eyes of 89 patients who underwent blepharoptosis surgery between June 2019 and October 2022. The margin reflex distance (MRD)-1 and MRD-2 were examined preoperatively and 3 months postoperatively in two groups: one with lower scleral show (LSS) (n = 37) and one without LSS (n = 118). The clinical characteristics of the two groups were compared. Both the LSS and non-LSS groups showed significant postoperative improvement in MRD-1 scores (p <.01, p <.01, respectively). MRD-2 was significantly reduced in the LSS group, while it remained unchanged in the non-LSS group (p <.01, p =.27, respectively). There were no significant differences between the two groups in age, sex, history of hard contact lens use, preoperative levator function, use of topical steroids, history of endophthalmic surgery, or history of filtration surgery; however, the LSS group significantly used prostaglandin analogs (PGAs) (p =.03). Postoperatively, MRD-2 decreased in 13 eyes (35.1%) and was maintained in 24 eyes (64.9%) in the LSS group and was maintained in all eyes in the non-LSS group. In the LSS group, we also examined the association between postoperative MRD-2 reduction and the use of PGAs and found that more patients with MRD-2 reduction used PGAs (p =.02). Lower scleral show in PGAs-associated blepharoptosis is expected to improve after blepharoptosis surgery. [ABSTRACT FROM AUTHOR]

Purpose: To report on the use of allogenous fascia lata (FL) grafts in patients with lower eyelid retraction (LER). Methods: In this retrospective study, a consecutive series of 27 patients (39 eyes) with LER who underwent lower eyelid elevation with FL was included. Examinations including measurement of the palpebral fissure vertical height (PFVH), the inferior scleral show distance, the margin reflex distance 2 (MRD 2), and the evaluation of conjunctival hyperemia were conducted at baseline and after a mean postoperative time of 25.9 ± 25.5 (5.0–81.0, median 13.0, last follow-up) months in all patients. Results: At the last follow-up, a significant reduction of the PFVH (11.3 ± 1.7 versus 12.8 ± 2.1 at baseline, p < 0.001), the inferior scleral show distance (0.7 ± 1.0 mm versus 2.1 ± 1.1 at baseline, p < 0.001), and the MRD 2 (6.4 ± 0.9 versus 7.8 ± 1.3 at baseline, p < 0.001) occurred. The conjunctival hyperemia grading score (McMonnies) was significantly reduced (1.8 ± 0.7) at the last follow-up compared to baseline (2.6 ± 0.6, p < 0.001). No case of ectropion or entropion was observed at the last follow-up visit. Conclusion: In this case series, lower eyelid elevation with FL grafts as a spacer led to a significant reduction of the PFVH, MRD 2, inferior scleral show distance, and conjunctival hyperemia. No severe surgery-related complications occurred. [ABSTRACT FROM AUTHOR]

Correction of lower eyelid retraction is necessary to restore adequate blink in paralytic lagophthalmos. A plethora of static and dynamic surgical techniques have been described for lower eyelid repositioning. This article provides an approach to management of the paralytic lower eyelid, including a summary of existing techniques, case examples, and surgical technique for in-office lower eyelid suspension using a palmaris longus tendon graft.

Lower eyelid retraction describes the inferior displacement of the lower eyelid with or without inversion or ectropion. Based on the causes of lower eyelid retraction, we divided the forming factors of lower eyelid retraction into three categories: (1) change in the balance of forces associated with the lower eyelid margin; (2) excessive loss of lower eyelid volume; (3) changes in the relative position of the eyeball and lower lid margin. In this review, the corresponding treatment methods are elaborated on individually for the above three forming factors. We also reported, for the first time, a new treatment for lower eyelid retraction. We created a dermal-orbicularis oculi suspension flap on the lateral side of the canthus and suspended it upward and inward on the dense connective tissue over the lateral bony surface of the orbital rim. The longest follow-up time was one year, and the results were satisfactory.

To compare the incidence of lower eyelid malposition following repair of isolated orbital floor fractures with that of complex orbitofacial fractures (defined as multi-wall fractures or prior orbital fracture repairs requiring revision) by oculofacial plastic surgeons via a transconjunctival or swinging eyelid approach. Retrospective review of 175 patients who underwent surgical repair of orbital fractures at our institution. The primary outcomes were the occurrence of lower eyelid malposition (ectropion, entropion, and eyelid retraction) and the need for subsequent surgical correction. Of 95 patients with isolated orbital floor fractures, 4 developed eyelid malposition (4.2%), 1 of which required surgical repair (1.1%). Of 80 patients with complex orbitofacial fractures (48 multi-wall fractures, 32 secondary revisions), 10 had pre-operative eyelid malposition and were excluded from further analysis. Fourteen of the remaining 70 patients developed postoperative eyelid malposition (20%), 3 of which required surgical repair (4.3%). The difference in the occurrence of eyelid malposition between groups was statistically significant (p =.001), but the difference in rates of those requiring subsequent repair was not (p =.182). There was no statistically significant difference in the occurrence of eyelid malposition when considering other surgical factors including lateral canthotomy, conjunctival closure, implant material, or anterior rim screws. The incidence of lower eyelid malposition following orbital fracture repair via a fornix-based approach was significantly higher for the repair of complex orbitofacial fractures than for isolated floor fractures. However, very few patients in either group required surgical repair for eyelid malposition. Surgical factors including implant material did not affect outcomes. [ABSTRACT FROM AUTHOR]

Purpose: To investigate the efficacy of Permacol™, a decellularized porcine dermal–derived membrane, as a spacer in the management of lower eyelid retraction. The efficacy of sizing and insertion was investigated, as well as complications. The literature was also reviewed to compare this material with other porcine-derived grafts in use for the management of lower eyelid retraction. Methods: This was a retrospective case series observing all patients who received lower eyelid Permacol implants by the two senior authors (AAM, TGH) for the management of lower eyelid retraction. Patient demographics, indications for surgery, graft size, degree of postoperative lid advancement, and complications were reviewed. Results: A total of 12 patients (16 eyelids) received Permacol implants for correction of lower eyelid retraction during the study period of 18 months (January 2015 to July 2017). Ten procedures were related to thyroid eye disease, 3 for reconstruction, 2 postcosmetic lower lid blepharoplasty, and one acquired anophthalmic socket. The average preoperative inferior scleral show (ISS) was 1.74 mm, and the average postoperative ISS was 0.82 mm. There was a mean lower eyelid elevation of 0.91 mm (p < 0.005, Wilcoxon signed rank test) and mean ratio of graft height:preoperative ISS was 3.8:1 over a median of 8 months follow-up. Conclusions: Permacol is a safe and effective alternative to autologous tissues for use as a spacer in patients with lower eyelid retraction of varying etiologies. It does undergo some resorption with time, however this can be predicted and incorporated into surgical planning; we recommend an implant height:ISS ratio of 4:1. [ABSTRACT FROM AUTHOR]

PURPOSE: The present study aimed to compare lower eyelid retraction (LER) in individuals with a positive orbital vector with that of individuals with a negative orbital vector. MATERIALS AND METHODS: This cross-sectional study was conducted on 123 normal individuals including 64 men and 59 women aged 20–80 years. After the individuals underwent Hertel exophthalmometry, two side-view and front-view photos were taken using a camera. The orbital vector angle and the extent of scleral show were then measured in millimeter, using the Photoshop software. Eventually, the recorded data were analyzed through statistical software. RESULTS: The findings of this study showed that LER has a significant correlation with orbital vector angle and the extent of proptosis (P < 0.05). The mean value of orbital vector angle in individuals without LER was 9.76°, while this figure was calculated to be − 13.65° in individuals with LER. The mean protrusion value based on Hertel exophthalmometry was 14.08 mm in individuals without LER and 16.27 mm in individuals with LER. The extent of scleral show had a significant correlation with proptosis and orbital vector angle (P = 0.01), with a mean value of − 0.41 mm in individuals without LER and 0.94 mm in participants with LER. CONCLUSIONS: The prevalence of LER and scleral show is positively correlated with the extent of proptosis and negatively correlated with orbital vector angle. [ABSTRACT FROM AUTHOR]

Purpose: The aim of the present study was to analyze quantitively the lower lid contour of patients with Graves orbitopathy. Methods: Bézier curves were manually adjusted to the ciliated and nasal (or lacrimal) portions of the lower lid contour of 41 patients with Graves orbitopathy and 43 normal subjects using National Institute of Health (NIH) ImageJ software. Considering the main coordinates of the Bézier functions, the Matlab software was employed to express the lid contours with 1000 points. The first order numerical derivative of the curves was calculated in order to compare the curvature of the whole lid contour of patients and controls. The same comparison was made for the temporal and nasal contour segments. Other parameters measured included the location of the lowest point on the contours (contour peak); the position of the lateral and medial canthi, as well as the angle formed by the lower lacrimal punctum and the vertex of the inner canthus. Results: The curvature of the temporal portion of the lid contours of patients and controls correlated with both the height of the lateral canthus and the magnitude of the MRD2. Graves retraction affects the medial and lateral portion of the lid. Both segments were more curved in patients than in controls. The lower punctum was significantly lowered, increasing the angle between the lower punctum and the medial canthus. Conclusions: The increased lateral curvature of the lower lid seen in patients with Graves disease is a natural geometric effect of the increment of MRD2. The nasal portion of the lid is also significantly lowered by retraction. [ABSTRACT FROM AUTHOR]

Background: It has been reported that the injection of the hyaluronic acid (HA) into the lower lid area could improve lower eyelid retraction. However, the published studies offered few insights into the mechanism of this treatment. When the underlying mechanism is not clear, many surgeons will not trust the method enough to apply it in their clinical practice. The purpose of this article was to propose a possible explanation for the underlying mechanism of the treatment and further verify the method by a series of cases. Methods: The authors performed a mechanical analysis on the physical impact of HA on the lower eyelid. In the clinical cases, we injected the fillers under the orbicularis muscle to correct lower lid retraction. The results were evaluated by the standardized marginal reflex distance 2 (MRD2) immediately and 9 months later. Results: From October 2013 to October 2015, the injections were carried out in 27 cases (14 post-blepharoplasty and 13 involuntary). In 26 cases (96.3%), the retraction was completely corrected and did not recur through the last follow-up. The average improvement of the standardized MRD2 was 0.84 mm immediately after the injection and 1.19 mm 9 months later. Complications were not reported. Conclusion: Lower eyelid retraction could be treated by the injection of HA under the orbicularis muscle. The filler in this situation acted as a lifter because the filler changed the balance of force of the lower lid, forcing it to shift upward to gain the new balance. The 'lifter' mechanism could be applicable to other facial injections that generate elevating effects.

Background: Cicatricial lower eyelid retraction is a challenging condition. It involves scarring of the lower eyelid, which causes it to retract and expose the sclera. This can lead to complications such as dry eye syndrome and corneal melting. It can be caused by trauma, burns, or previous eyelid surgery. Detailed assessment and understanding of eyelid anatomy and retraction are critical for successful surgical planning. Dynamic and static examinations of the eyelid including measurements of the lower eyelid margin reflex distance (MRD2) and scleral show are also essential to determine the appropriate treatment approach., Methods: A systematic review was conducted using Medline, Scopus, and Cochrane databases with keywords related to cicatricial lower eyelid retraction. The publication language was limited to English after 2000. A total of 29 articles were included for data extraction and analysis., Results: The main surgical techniques include tarsoconjunctival grafts, spacers, midface lift, and lateral canthal tendon suspension, although no single procedure has been universally recognized as the gold standard. New innovations such as synthetic grafts and xenografts are being explored for their potential in eyelid reconstruction. Severe cases, defined as those with inferior scleral show greater than 2 mm, may require a combination of reconstruction methods., Conclusions: Correcting cicatricial lower eyelid retraction is a major challenge in oculoplastic reconstruction. The surgical approach should be individualized, considering the pathologies and etiologies of lid retraction. In-depth knowledge and careful surgical planning are essential for best outcomes. There is no gold standard technique, and postoperative outcomes, complications, and management vary depending on the surgical approach used.

Purpose: Orbital decompression for thyroid eye disease (TED) has been noted to improve lower lid retraction by 0.5-1 mm. We hypothesize that orbital decompression via transconjunctival approach may lead to increased reduction in marginal reflex distance 2 (MRD2) as it involves division of the lower lid retractors. The purpose of this study is to evaluate relative changes in lower lid position for patients undergoing lateral and transconjunctival orbital decompression, respectively. Methods: In this cross-sectional study, all TED patients managed with lateral or transconjunctival orbital decompression for a 3-year period were screened for inclusion. Photographs taken in the primary position preoperatively and three months postoperatively were utilized to evaluate the MRD2 from each patient. Measurements were made utilizing NIH ImageJ software standardized to a corneal diameter. Hertel measurements of proptosis were obtained pre and postoperatively. The primary outcome measure was MRD2 in operative eyes. Results: A total of 131 (86 patients) operative eyes were included in the sample. Mean change MRD2 was not significantly different between the surgical groups (p = 0.07). In multivariate modeling, mean change in MRD2 was significantly associated with change in exophthalmometry, independent of surgical approach. Conclusions: The association between decrease in Hertel measurement and decrease in MRD2 is consistent with the existing literature on the topic. It appears that transconjunctival division of the lower eyelid retractors provides no additional benefit in reducing lower lid retraction relative to change in proptosis. [ABSTRACT FROM AUTHOR]

This article describes our surgical technique for subperiosteal midface elevation in patients with paralytic lower eyelid malposition or cicatricial inferior eyelid retraction. Nineteen patients with paralytic lower eyelid malposition and 15 patients with cicatricial inferior eyelid retraction underwent a subperiosteal midface lift (n= 34). The procedure was performed under local anesthesia through three nonvisible incisions. A transconjunctival incision allows preseptal dissection to the orbital rim, followed by a subperiosteal dissection of the midface. An oral incision is useful to achieve complete subperiosteal dissection and to perform the distal periostomy, which allows complete release of the midface soft tissues. A temporal incision provides access to the temporal fascia for fixation of the elevated tissues and gives the surgeon the possibility of removing redundant skin from the scalp instead of the lower eyelid. Additional posterior lamellar grafting was performed in 24 patients. There was a statistically significant reduction in the distance from the pupil centre to the lower eyelid (margin reflex distance, MRD2) 1 month after surgery (preoperative MRD2 9.62 ± 4.52 mm, postoperative MRD2 5.28 ± 2.62 mm). The ectropion and lower eyelid retraction was resolved in all patients, except for one recurrence. Midfacial elevation is a safe and effective surgical technique in the treatment of static lower eyelid malposition after chronic facial nerve palsy or posttraumatic or iatrogenic lower eyelid retraction.

Purpose To evaluate the histological appearances of the epithelial cells and the clinical effect of the hard palate mucous membrane ( HPM) graft for the treatment of lower eyelid retraction ( LER). Methods This was a follow-up study involving 15 patients, with a total of 16 eyes operated. Five patients had LER as a result of Graves' ophthalmopathy and/or inferior rectus recession, six patients because of wearing an eye prosthesis, two patients because of previous tumour excision, one patient because of proptosis due to sphenoid wing meningioma and one patient because of previous lower eyelid blepharoplasty. Three imprint biopsies were taken from each patient, one from the tarsal conjunctiva in the healthy eye, one from the graft in the operated eye and one from unoperated hard palate. The inferior scleral show was measured on pre- and postoperative photographs and related to the horizontal corneal diameter. Results Median follow-up time was 21.2 [range 4.5-87.9] months. Imprints from the graft and the hard palate showed equally large epithelial cells; imprints from conjunctiva showed small epithelial cells. The mean (± SD) scleral show was 0.12 ± 0.09 cornea diameter before surgery and 0.0003 ± 0.08 cornea diameter at invited follow-up (p < 0.001, paired t-test). Corrected for direction of gaze, the mean improvement in scleral show was 0.12 ± 0.08 cornea diameter. Thirteen of 14 patients were satisfied with the final result. Conclusion A HPM graft for LER maintains its native epithelial morphology and gives a lasting improvement in most patients. [ABSTRACT FROM AUTHOR]

Objective: Among the surgical procedures used to correct the positions of the eyelids or improve their cosmetic appearance, procedures for treating eyelid retraction are some of the most challenging. Lower eyelid retraction can occur iatrogenically after various surgical procedures. We performed a successful corrective procedure for lower eyelid retraction, which had occurred at some point in the 2 decades after primary surgery for epiblepharon. Method: A 23-year-old woman underwent primary surgery for bilateral epiblepharon at the age of 5 years. However, at the age of 17, she noticed that an abnormally large proportion of her right sclera was visible when her eyes were in their natural position. In the primary position of gaze, the distance from the lower limbus of the right cornea to the upper margin of the lower eyelid was approximately 2 mm. An incision was made in the lower eyelid along the scar caused by the previous operation. Subsequently, the connections between the tarsus and the lower eyelid retractors were broken, and harvested auricular cartilage was placed between the lower edge of the tarsus and the lower eyelid retractors. Results: One year after the operation, there was no gross difference in the distance between the lower margin of the corneal limbus and the lower eyelid on either side, and the patient was extremely happy with the results. Conclusion: Using a novel surgical technique, we successfully lengthened the posterior layer of the lower eyelid retractors with a small amount auricular cartilage, resulting in good functional and cosmetic outcomes.

Background: This report aims to describe a paranasal flap technique for reconstruction of lower eyelid retraction and ectropion. Methods: After the contracture of the lower eyelid skin or conjunctiva had been thoroughly released, the ipsilateral upper pedicle paranasal flap was designed according to the size of the lower eyelid skin wound. After dissection of the flap, the subcutaneous tissue of the flap was trimmed according to the depth of the wound, the flap was rotated to cover the defect, and an anchor was fixed to the distal aspect of the outer canthus. The secondary defect of the donor area was sutured directly. Results: In this study, 67 patients with lower eyelid defects resulting from correction of eyelid retraction and ectropion were reconstructed using paranasal flaps between April 2004 and October 2009. The sizes of the paranasal flaps ranged from 0.6 × 2.2 to 1.5 × 3.5 cm. At the follow-up assessment, the patients could close their eyes easily and completely without lagophthalmos, and neither the upper lips or the nasal ala showed any anatomic deformities. The features of the paranasal flaps, such as skin color, texture, and contour of the repaired tissue, were a good match with the surrounding skin. The suture lines of the donor areas were sheltered well. Conclusions: Paranasal flaps were used for effective reconstruction of lower eyelid retraction or ectropion, with achievement of good eyelid function and a good color, contour, and texture match with the surrounding skin. Overall, the functional and cosmetic results were satisfactory. Level of Evidence V: This journal requires that authors assign a level of evidence to each article.

Abstract: Purpose: The transconjunctival, subciliary, subtarsal, and subpalpebral approaches for accessing the infraorbital rim and orbital floor have both advantages and disadvantages. The most common complications include rounding of the lateral canthal angle, lower eyelid retraction with inferior scleral show, and frank ectropion. Materials and patients: From 2000 to 2007, we treated 29 patients with lower eyelid malposition after surgery to manage the floor and infraorbital trauma (22 subciliary approaches, five transconjunctival approaches and lateral canthotomies, and two transconjunctival approaches). To correct lower eyelid malposition, we applied the tarsal strip technique in all patients. Results: Twenty-five patients had scleral show and four patients had ectropion: three were previous treated using transconjunctival access and one using subciliary access. Twenty-six patients obtained satisfactory correction of eyelid malposition in a single-step surgical procedure, while three patients required a second surgical step to correct the remaining scleral show. Good aesthetic and functional results were achieved in all cases. Conclusions: All approaches to the infraorbital rim or orbital floor have the potential for postoperative sequelae. The tarsal strip technique is a relatively simple technique that oral and maxillofacial surgeons can use to manage lower lid malposition, such as scleral show and ectropion. [Copyright &y& Elsevier]
