- Abstract
Purpose: The purpose of this study is to determine the public's perception of the scope of practice for oculofacial plastic and reconstructive surgeons (OFPRS)., Methods: A 49-question survey was distributed by Qualtrics
Ⓡ to a panel similar to the US demographic composition. Responses collected underwent bivariate statistical analysis., Result: A total of 530 responses were obtained, with most respondents being white, female, over the age of 35, from the Midwest, and with at least a college education or above. Most respondents did not think ophthalmologists or optometrists were surgeons, and only 158 people (29.8%) knew the primary specialty of OFPRS was ophthalmology. Board certification was preferred by 98.87% of respondents, and 95.28% preferred ASOPRS-trained OFPRS., Conclusions: Our study highlights the gap in knowledge about OFPRS as a field, the qualifications and training required, and the scope of practice. Notably, even for OFPRS-specific procedures, PRS remained the leading subspecialist chosen for interventions such as orbital decompression (58.5% vs. 71.5%), orbital reconstruction (57.9% vs. 74.2%), enucleation/evisceration (48.1% vs. 53.4%), optic nerve-related surgery (39.8% vs. 43.4%), orbital cancer resection (42.8% vs. 46.8%), and tear duct surgery (41.9% vs. 52.5%). Additionally, most respondents did not feel that facial fillers, laser skin resurfacing, eyelid cancer removal, or cataract surgery were within the OFPRS scope of practice.- Published

- Abstract
Background: Intraosseous hemangiomas are rare benign tumors comprising fewer than 1% of all osseous tumors; even more uncommon are intraosseous hemangiomas of the zygomatic bone. This case reports a multidisciplinary approach for excision and reconstruction of an intraosseous hemangioma of the zygomatic bone in a 54-year-old female., Methods: Multidisciplinary approach with both otolaryngology head and neck surgery and oculofacial plastics and reconstructive surgery included right lateral canthotomy and right transconjunctival orbitotomy with en-bloc excision of the zygomatic arch, followed by reconstruction of the orbital rim, orbital floor, and eyelid with Medpor implant., Results: Final surgical pathology was consistent with intraosseous hemangioma of the zygomatic bone. At 4-month follow-up, the patient was healing well with good midface projection and without any visual deficits., Conclusions: A multidisciplinary coordinated case allowed us to meet the standard of maintaining cosmesis and function while undergoing resection of a rare tumor involving a key facial structure-the zygoma. Involvement of oculofacial plastics and reconstructive surgery service allowed for advanced eyelid reconstruction techniques to limit any functional impairment to our patient with deliberate choice of implant material for well-adhered, durable, and aesthetically optimal reconstruction of the right malar eminence, lateral orbital rim, and orbital floor defect. The postoperative result through the multidisciplinary approach was a near symmetrical facial reconstruction without any associated eyelid or globe abnormalities., Competing Interests: Disclosures: The authors declare no financial disclosures or conflicts of interest related to the research described in this manuscript., (© 2024 HMP Global.

- Abstract
Background Ophthalmology is a unique specialty with limited exposure during medical school. To improve the transition to ophthalmology residency, the Accreditation Council for Graduate Medical Education (ACGME) announced in 2017 that all ophthalmology residency programs would move to a combined post-graduate year (PGY) 1 year with mandatory integration by 2023. Currently, there are no standardized guidelines from the American Board of Ophthalmology (ABO) or the Accreditation Council for Graduate Medical Education (ACGME) to address ophthalmology resident competence prior to becoming the primary contact for inpatient and emergency room (ER) consultations as a PGY-2. Novice residents may not be equipped to accurately diagnose vision or life-threatening ocular conditions. A balance between resident autonomy and supervision is required for proper training without increasing patient morbidity and mortality. Objective This study's objective is to examine the diagnostic accuracy of PGY-2 ophthalmology non-integrated residents on call to standardize supervision requirements (through buddy-call) prior to initiating indirectly supervised calls. Methods All inpatient and ER ophthalmology consults for the first seven weeks of the year evaluated by PGY-2 (junior) residents were supervised and graded as "correct" or "incorrect" by PGY-4 (senior) residents. Results One hundred forty-eight consults were seen over 30 call days over a period of seven weeks (4.93 consults per call). The percentage of correct diagnoses increased with each successive week (R
2 = 0.9581; correlation = 0.979). The greatest percent increase of correctly diagnosed encounters was between weeks 2 and 3 (19.14%) correlating to call numbers 10-16 and 45-68 patient encounters. The mean percent accuracy surpassed 70% during weeks 3-4, and improvement continued to week 7. High-acuity diagnoses were identified consistently 100% of the time from week 5 onward. Conclusion Our analysis indicated that diagnostic accuracy was greater than 70% between weeks 3 and 4 with high-acuity diagnostic accuracy reaching 100% at week 5. It can be postulated that optimal direct senior resident supervision is needed for at least 3-5 weeks before transitioning to indirectly supervised calls by PGY-2 residents. This standardization would allow junior residents to acquire sufficient clinical experience to accurately make a diagnosis and prevent patient morbidity. Further research nationally is necessary prior to creating a standardized call structure for PGY-2 residents especially with the newly mandatory integrated ophthalmology residency programs., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2024, Hashemi et al.)- Published

- Abstract
As the use of teprotumumab for thyroid eye disease (TED) becomes more prolific, there remains a scarcity of literature regarding the associated side effects and adverse events of teprotumumab use. The authors present a single-center retrospective, observational case review of TED patients who received at least a single dose of teprotumumab infusion at the oculofacial plastic surgery service between February 2020 and July 2023. The most predominant recollected side effects were fatigue, brittle nails, dry eye symptoms, hair loss, muscle spasms, and dry mouth. Significant adverse events were limited to two cases of a blood clot and a single case of pulmonary embolism. This is the first retrospective study of patient-reported side effects and adverse events experienced by a cohort of teprotumumab users., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2024, Mukit et al.)

- Abstract
The incidence of penetrating orbital injuries from writing instruments continues to rise in the pediatric population. Such injuries can cause significant visual morbidity and have a lifelong psychosocial impact. While the description of graphite pencil-related orbital trauma management is well demonstrated with over 40 reported cases, a lack of consistent management protocol for colored pencil-related injuries. Here, we report an inadvertent penetrating orbital colored pencil injury with progressive mechanical ptosis and pre-septal cellulitis necessitating urgent orbitotomy, debridement, and washout to reduce inflammatory and infectious burden. The wooden body serves as a nidus for polymicrobial infection, and the unique composition of colored pencil cores may lead to inflammatory processes that require vigilant multidisciplinary surgical and medical management reflected in our literature review.

- Abstract
Purpose: The integrity of the orbit has a finite structural limit due to the compliance of its tissue. The authors investigate these limits to quantify them and inform the treatment of heightened ocular and orbital pressure., Methods: Cadaveric study with 12 orbits being volumized before randomization of treatment for pathologic levels of ocular and orbital pressure. First-line and second-line treatment was chosen randomly (lateral cantholysis, superior septolysis, inferior septolysis). Prior to treatment, IOP, orbital compartment pressure, and axial globe projection was measured after delivery of each 1cc aliquot and surgical treatment., Results: Orbital compartment pressure and IOP were well correlated (r = 0.99). The average reduction in IOP after treatment averaged a 56.2 mm Hg reduction in IOP. All treatments were statistically equivalent ( p < 0.01). Loss of compliance (P LOC ) was determined when the mean plus 1 standard deviation of change in IOP/ml volume was achieved with simultaneous change in exophthalmometry of <0.5 mm change/ml added volume, indicating an acceleration in pressure in the face of a steady volume. This criteria was met for 11 of 12 orbits. The 12th orbit missed this threshold by 1 mm Hg in IOP. P LOC occurred at an average IOP of 43.0 mm Hg (±5.8 mm Hg, 90% CI) and after an average injection of 13 ml (±1.4 mm, 90% CI). Additionally, lateral cantholysis, superior septolysis, and inferior septolysis were statistically equivalent in reducing IOP after P LOC ., Conclusions: IOP and orbital compartment pressure are excellent proxies for each other in the authors' model. Orbital compliance is a mathematic phenomenon that can be quantified, as evident in this investigation. P LOC can inform timing for orbital decompressions in the presence of heightened IOP. Multiple procedures can be used to extinguish dangerously high orbital compartment pressure., (Copyright © 2023 The American Society of Ophthalmic Plastic and Reconstructive Surgery, Inc.)

- Abstract
Context: Early inflammatory thyroid eye disease (TED) can lead to symptomatic chronic disease, including disabling proptosis. Teprotumumab, an insulin-like growth factor-1 receptor (IGF-1R) inhibitor, previously demonstrated efficacy in acute, high-inflammation TED trials., Objective: We present data from the first placebo-controlled trial with teprotumumab in chronic/low disease activity TED., Methods: This randomized double-masked, placebo-controlled trial, conducted at 11 US centers, enrolled adult participants with TED duration of 2 to 10 years, Clinical Activity Score (CAS) ≤ 1 or no additional inflammation or progression in proptosis/diplopia for ≥1 year, proptosis ≥3 mm from before TED and/or from normal, euthyroid/mildly hypo/hyperthyroid, no prior teprotumumab, and no steroids within 3 weeks of baseline. Patients received (2:1) intravenous teprotumumab or placebo once every 3 weeks (total 8 infusions). The primary endpoint was proptosis (mm) improvement at Week 24. Adverse events (AEs) were assessed., Results: A total of 62 (42 teprotumumab and 20 placebo) patients were randomized. At Week 24, least squares mean (SE) proptosis improvement was greater with teprotumumab (-2.41 [0.228]) than with placebo (-0.92 [0.323]), difference -1.48 (95% CI -2.28, -0.69; P = .0004). Proportions of patients with AEs were similar between groups. Hyperglycemia was reported in 6 (15%) vs 2 (10%) and hearing impairment in 9 (22%) vs 2 (10%) with teprotumumab and placebo, respectively. AEs led to discontinuation in 1 teprotumumab (left ear conductive hearing loss with congenital anomaly) and 1 placebo patient (infusion-related). There were no deaths., Conclusion: Teprotumumab significantly improved proptosis vs placebo in longstanding/low inflammation TED, demonstrating efficacy regardless of disease duration/activity. The safety profile was comparable to that previously reported., (© The Author(s) 2023. Published by Oxford University Press on behalf of the Endocrine Society.)

- Abstract
The authors report a penetrating orbitocerebral vape pen injury necessitating a primary enucleation and craniotomy to remove the foreign body fragments. A 31-year-old male presented with acute right vision loss after a modifiable vape pen explosion launched multiple projectile fragments into his right eye. CT revealed a deformed globe with multiple radiodense curvilinear fragments in the superior orbital roof and intracranial space. A right frontal craniotomy and orbitotomy with removal of vape pen fragments, reconstruction of the orbital roof, primary enucleation, and eyelid repair were performed in conjunction with neurosurgery. To the best of the authors' knowledge, this is the first reported penetrating globe injury from a vape pen explosion., Competing Interests: The authors have no financial or conflicts of interest to disclose., (Copyright © 2023 The American Society of Ophthalmic Plastic and Reconstructive Surgery, Inc.)

- Abstract
HSV-1 disease is a significant public health burden causing orofacial, genital, cornea, and brain infection. We previously reported that a trivalent HSV-2 gC2, gD2, gE2 nucleoside-modified mRNA-lipid nanoparticle (LNP) vaccine provides excellent protection against vaginal HSV-1 infection in mice. Here, we evaluated whether this HSV-2 gC2, gD2, gE2 vaccine is as effective as a similar HSV-1 mRNA LNP vaccine containing gC1, gD1, and gE1 in the murine lip and genital infection models. Mice were immunized twice with a total mRNA dose of 1 or 10 µg. The two vaccines produced comparable HSV-1 neutralizing antibody titers, and surprisingly, the HSV-2 vaccine stimulated more potent CD8
+ T-cell responses to gE1 peptides than the HSV-1 vaccine. Both vaccines provided complete protection from clinical disease in the lip model, while in the genital model, both vaccines prevented death and genital disease, but the HSV-1 vaccine reduced day two vaginal titers slightly better at the 1 µg dose. Both vaccines prevented HSV-1 DNA from reaching the trigeminal or dorsal root ganglia to a similar extent. We conclude that the trivalent HSV-2 mRNA vaccine provides outstanding protection against HSV-1 challenge at two sites and may serve as a universal prophylactic vaccine for HSV-1 and HSV-2.- Published

- Abstract
Herpes simplex virus type 2 (HSV-2) is a leading cause of genital ulcer disease and a major risk factor for acquisition and transmission of HIV. Frequent recurrent genital lesions and concerns about transmitting infection to intimate partners affect the quality of life of infected individuals. Therapeutic vaccines are urgently needed to reduce the frequency of genital lesions and transmission. S-540956 is a novel vaccine adjuvant that contains CpG oligonucleotide ODN2006 annealed to its complementary sequence and conjugated to a lipid that targets the adjuvant to lymph nodes. Our primary goal was to compare S-540956 administered with HSV-2 glycoprotein D (gD2) with no treatment in a guinea pig model of recurrent genital herpes (studies 1 and 2). Our secondary goals were to compare S-540956 with oligonucleotide ODN2006 (study1) or glucopyranosyl lipid A in a stable oil-in-water nano-emulsion (GLA-SE) (study 2). gD2/S-540956 reduced the number of days with recurrent genital lesions by 56%, vaginal shedding of HSV-2 DNA by 49%, and both combined by 54% compared to PBS, and was more efficacious than the two other adjuvants. Our results indicate that S-540956 has great potential as an adjuvant for a therapeutic vaccine for genital herpes, and merits further evaluation with the addition of potent T cell immunogens.

- Abstract
Orbital implant materials have evolved greatly over the past century and include but are not limited to metal, ceramic, polymer, silicone, and glass. Knowledge of historically used materials is clinically relevant to patient care as certain materials carry a greater risk of migration, extrusion, infection, and limitations for imaging modalities utilized to visualize adjacent structures. We report an unusual case of an 80-year-old male who presented to our community hospital with seizure-like activity. CT imaging of the brain revealed several white matter and cortex lesions with the largest lesion measuring 2.5 × 2 × 1.9 cm. The patient had a history of enucleation with placement of an orbital implant following a penetrating injury to the left eye at four years of age. Hounsfield scale analysis was read by radiology as being most consistent with a thin metallic shell surrounding the orbital implant. The potential for metallic material was consistent with the implant's age and time of placement. Few reviews on ocular implant materials from this period exist in the current medical literature. A single case report discussing a hollow metal orbital implant with similar-appearing imaging was identified. Due to concern for possible metal implant materials, the patient underwent implant exchange so MRI imaging could safely be performed. Intraoperatively, the implant was identified as a clear, hollow, non-metallic, non-porous polymer sphere. Following surgery, the patient was able to undergo appropriate neuroimaging with subsequent diagnostic biopsy. Current literature reviewing CT or photographic imaging of ocular implant devices prior to the 1940s is limited. This case highlights the importance of detailing materials historically used in orbital implants, their effects on clinical decision-making, and the utility of Hounsfield scale values to identify a material's radiodensity on CT imaging., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2022, Anderson-Quiñones et al.)

- Abstract
Purpose: To assess extended release/long acting (ER/LA) opioid prescribing patterns among ophthalmic plastic surgeons in the Centers for Medicare and Medicaid Services (CMS) Part D database., Methods: A retrospective observational cohort study was conducted on oculoplastic surgeons in the CMS Part D database who prescribed ER/LA opioids from 2013 to 2017. American Society of Ophthalmic Plastics and Reconstructive Surgery (ASOPRS) and non-ASOPRS surgeons were analyzed as groups. Prescribers were also analyzed based on gender and practice experience., Results: Oculoplastic surgeons (64 ASOPRS and 78 non-ASOPRS) were responsible for 1,177 ER/LA opioid prescriptions from 2013 to 2017. ASOPRS members accounted for 4.6% and non-ASOPRS members accounted for 7.5% of all ER/LA opioids prescribed by ophthalmologists over the study period ( p = .02). The total number of ASOPRS and non-ASOPRS members prescribing ER/LA opioids decreased by 52% ( p = .10) and 58% ( p = .07) from 2013 to 2017 respectively., Conclusion: ER/LA opioids are indicated for treatment of chronic pain and may be appropriately prescribed by the oculoplastic surgeon in certain circumstances, however due to the higher risk of overdose injury, those circumstances must be defined and justified. While a relatively small number of oculoplastic surgeons (10.6% ASOPRS and 19.6% non-ASOPRS) prescribed ER/LA opioids from 2013 to 2017, non-ASOPRS oculoplastic surgeons wrote 23.5% more ER/LA opioid prescriptions over the study period. Over the 5-year study period there was a general decline in the prescribing of ER/LA opioids by oculoplastic surgeons. Reviewing the prescribing practices of oculoplastic specialists, regardless of professional affiliation, is necessary to understand the role of ER/LA opioids for all of ophthalmology.

- Abstract
Purpose: To report an unusual case of spontaneous orbital hemorrhage in the setting of DIC and hepatic failure., Observations: A 33-year-old female presented to the Emergency Department (ED) with acute liver failure. During the first week of her hospital admission, she developed unilateral eyelid swelling and proptosis, prompting a consult to ophthalmology. Additional physical examination revealed significantly decreased visual acuity, extraocular muscle restriction, afferent pupillary defect, and increased intraocular pressure. Computed tomography (CT) and ultrasound confirmed the diagnosis of intraorbital hemorrhage. Aggressive management in the form of lateral canthotomy, cantholysis, and septolysis was unable to be performed due to the patient's multiple comorbidities outweighing the potential benefits., Conclusions and Importance: This rare phenomenon is unique from previous existing literature in that the timing of the incident limited the therapeutic options for this patient, additional imaging in the form of ultrasound was utilized in the work-up, and to our knowledge this is the second case of spontaneous orbital hemorrhage as a complication of disseminated intravascular coagulation (DIC) caused by hepatic failure., Competing Interests: The following authors have no financial disclosures., (© 2022 The Authors.

- Abstract
Purpose: To evaluate teprotumumab safety/efficacy in patients with thyroid eye disease (TED) who were nonresponsive or who experienced a disease flare., Design: The Treatment of Graves' Orbitopathy to Reduce Proptosis with Teprotumumab Infusions in an Open-Label Clinical Extension Study (OPTIC-X) is a teprotumumab treatment and re-treatment trial following the placebo-controlled teprotumumab Phase 3 Treatment of Graves' Orbitopathy (Thyroid Eye Disease) to Reduce Proptosis with Teprotumumab Infusions in a Randomized, Placebo-Controlled, Clinical Study (OPTIC) trial., Participants: Patients who previously received placebo (n = 37) or teprotumumab (n = 14) in OPTIC., Methods: OPTIC nonresponders or those who flared (≥2-mm increase in proptosis, ≥2-point increase in clinical activity score [CAS], or both) during follow-up were treated for the first time (previous placebo patients) or re-treated with teprotumumab in OPTIC-X with 8 infusions over 24 weeks., Main Outcome Measures: Proptosis response and safety. Secondary outcomes included proptosis, CAS, subjective diplopia, and quality-of-life., Results: Thirty-three of 37 placebo-treated OPTIC patients (89.2%) became proptosis responders (mean ± standard deviation, -3.5 ± 1.7 mm) when treated with teprotumumab in OPTIC-X. The responses were equivalent to the OPTIC study. In these responders, proptosis, CAS of 0 or 1, and diplopia responses were maintained in 29 of 32 patients (90.6%), 20 of 21 patients (95.2%), and 12 of 14 patients (85.7%), respectively, at follow-up week 48. The median TED duration was 12.9 months versus 6.3 months in those treated with teprotumumab in the OPTIC study. Of the 5 OPTIC teprotumumab nonresponders re-treated in OPTIC-X, 2 responded, 1 showed a proptosis reduction of 1.5 mm from OPTIC baseline, and 2 discontinued treatment early. Of the OPTIC teprotumumab responders who experienced flare, 5 of 8 patients (62.5%) responded when re-treated (mean proptosis reduction, 1.9 ± 1.2 mm from OPTIC-X baseline and 3.3 ± 0.7 mm from OPTIC baseline). Compared with published double-masked trials and their integrated follow-up, no new safety signals were identified. Mild hearing impairment was reported; 4 events occurred during the first course of treatment, and 2 events reoccurred after re-treatment., Conclusions: Patients with TED of longer disease duration responded similarly to those treated earlier in the disease course. Patients with an insufficient initial response or flare may benefit from additional teprotumumab therapy. No new safety risk was identified; however additional postmarketing pharmacovigilance is ongoing., (Copyright © 2021 American Academy of Ophthalmology. Published by Elsevier Inc.

- Abstract
The toxicity of mRNA-lipid nanoparticle (LNP) vaccines depends on the total mRNA-LNP dose. We established that the maximum tolerated dose of our trivalent mRNA-LNP genital herpes vaccine was 10 μg/immunization in mice. We then evaluated one of the mRNAs, gD2 mRNA-LNP, to determine how much of the 10 μg total dose to assign to this immunogen. We immunized mice with 0.3, 1.0, 3.0, or 10 μg of gD2 mRNA-LNP and measured serum IgG ELISA, neutralizing antibodies, and antibodies to six crucial gD2 epitopes involved in virus entry and spread. Antibodies to crucial gD2 epitopes peaked at 1 μg, while ELISA and neutralizing titers continued to increase at higher doses. The epitope results suggested no immunologic benefit above 1 μg of gD2 mRNA-LNP, while ELISA and neutralizing titers indicated higher doses may be useful. We challenged the gD2 mRNA-immunized mice intravaginally with HSV-2. The 1-μg dose provided total protection, confirming the epitope studies, and supported assigning less than one-third of the trivalent vaccine maximum dose of 10 μg to gD2 mRNA-LNP. Epitope mapping as performed in mice can also be accomplished in phase 1 human trials to help select the optimum dose of each immunogen in a multivalent vaccine.

- Abstract
Significance: This study aimed to determine the prescription rates and prescribing trends of opioids by optometrists in the Centers for Medicare & Medicaid Services (CMS) part D database from 2013 to 2017 and to assess opioid prescribing patterns of U.S. optometrists in the CMS part D database., Methods: With internal review board approval, a retrospective observational cohort study was conducted on optometrists listed in the CMS part D database who prescribed opioids from 2013 to 2017., Results: There was an average of 26,477 optometrists in the CMS database from 2013 to 2017, of which 5.9% prescribed opioids. Of those prescribing opioids, optometrists wrote an average of 5.9 opioid prescriptions per year. Those writing greater than 10 opioid prescriptions averaged 24.2 annually. Overall, of opioid prescribing optometrists, opioid prescriptions comprised 7% of prescriptions written per year., Conclusions: Most optometrists do not prescribe opioids, and the vast majority of those who do write few opioid prescriptions. The total number of optometrists prescribing opioids and the total number of opioid prescriptions declined from 2013 to 2017. Further investigation into the opioid prescribing practices by optometrists will help better understand specific pain needs, as opioid prescribing patterns may differ depending on patient population., Competing Interests: Conflict of Interest Disclosure: LRA is a consultant for Novartis Pharmaceuticals.

- Abstract
Purpose: : To evaluate the cost, safety, surgical outcome, and efficacy of modified Cutler-Beard eyelid reconstruction utilizing a novel silicone plate as a tarsal plate replacement in the repair of 60% to 100% eyelid defects following the excision of large malignant tumors., Methods: : A prospective, noncomparative, interventional study of 30 eyes was done over 3 years. Fourteen patients were female, and 16 patients were male. In all the cases, a silicone plate, the synthetic, artificial tarsal plate, was utilized for a total or subtotal replacement of the tarsal plate. The created defect was measured in mm (length and width) and later expressed in percentage. Pre- and postoperative action of levator palpebrae superioris (LPS) was measured. Pre- and postoperative measurements of the margin-to-margin reflex distance (MRD1) were noted., Results: : Preoperative LPS action was 1.23 ± 1.35 mm, whereas postoperative LPS actions at the end of 1 week and 18 months were 11. 8 ± 0.88 mm and 13.53 ± 0. 73 mm, respectively. Preoperative MRD1 was - 3.0 ± 1.144 mm, whereas postoperative MRD1 values at the end of 1 week and 18 months were 2.18 ± 0.27 mm and 4.16 mm ± 0.35, respectively. The mean created defect after the removal of the tumor was 87.3% ±11.10. The mean length of the silicone plate implanted in this study was 27.53 ± 2.48 mm. The follow-up period for the study participants was 18 months., Conclusion: : The synthetic novel silicone plate was successful as a tarsal plate replacement. A second surgical site for ear cartilage harvesting is avoided. Cadaver transfer of Achilles tendon carries the risk of transmission of communicable diseases, for example, hepatitis B and HIV. Silicone is an inert, nonreacting, and tissue-tested material, thus eliminating the possibility of graft rejection. This material is readily available and cost-effective. The novel silicone plate is considered to be the most promising alternative material as a tarsal replacement in the future generation., Competing Interests: None

- Abstract
Abstract: The Muller muscle-conjunctival resection is a common technique used to treat blepharoptosis, but there is variability with the target surgical resection and expected postoperative outcomes measured by marginal reflex distance-1 (MRD1). A Levator-Mullerectomy is a novel surgical approach described by Morris et al to incorporate the levator palpebrae superioris in the same incision as the classic Muller muscle-conjunctival resection in the treatment of blepharoptosis. This a retrospective study of patients who underwent Levator-Mullerectomy for ptosis repair showing the clinical outcomes based on MRD1. Statistical analysis was performed using analysis of variance and a nonparametric Kruskal-Wallis test. One hundred-twelve eyes of 83 patients (29 bilateral cases) with a mean age 64.6 years (7-92 years) were included. The types and prevalence of blepharoptosis were involutional (83%), neurogenic (8.0%), traumatic (3.6%), apraxia (2.7%), and congenital (2.7%). There was no significant difference in clinical outcome based on type of blepharoptosis (P = 0.7). Target resection lengths of 8 mm, 10 mm, and 12 mm were compared with postoperative MRD1 change. The mean change in MRD 1 between 8 mm and 10 mm was found to be statistically significant (P = 0.001 for both) but was not statistically significant for the 12 mm resection (P = 0.8). In patients with blepharoptosis and a positive response to 2.5% phenylephrine can benefit from Levator-Mullerectomy with either an 8 mm or 10 mm resection. This novel surgical approach allows surgeons to produce a more predictable and consistent clinical outcome., Competing Interests: The authors report no conflicts of interest., (Copyright © 2021 by Mutaz B.

- Abstract
Eye trauma is frequently seen by non-ophthalmology providers. This article elucidates a methodological approach to eye trauma. The first step is to address any life-threatening conditions. Then a focused history and exam is discussed, starting externally. Then, key history, physical, pathophysiology, and basic management of common, serious eye injuries are discussed: chemical injury, orbital fractures, open globe, traumatic hyphema, retinal detachment, traumatic optic neuropathy, and eyelid laceration. Finally, we highlight the practicality of telemedicine for areas where ophthalmology coverage is lacking., Competing Interests: Conflict of interest: None., (© Copyright 2021 by the American Board of Family Medicine.)

- Abstract
Non-arteritic ischemic optic neuropathy (NAION) is thought to be caused by loss of blood flow to the optic nerve which in turn causes an acute, unilateral and painless vision loss that affects older vasculopathic patients. We report a case of a 43-year-old Hispanic male with the classic presentation of NAION in the setting of a coronavirus disease 2019 (COVID-19) infection. It is well documented that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can cause hypoxemia and thrombophilia in patients, both of which may contribute to the development of NAION. It is uncertain whether the association of NAION and COVID-19 was causal or coincidental but the purpose of this case report is to argue that there is biological plausibility and to help shed light on potential ophthalmologic complications of COVID-19., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2020, Rho et al.)

- Abstract
Purpose: To develop a deep learning model for objective evaluation of experimental autoimmune uveitis (EAU), the animal model of posterior uveitis that reveals its essential pathological features via fundus photographs., Methods: We developed a deep learning construct to identify uveitis using reference mouse fundus images and further categorized the severity levels of disease into mild and severe EAU. We evaluated the performance of the model using the area under the receiver operating characteristic curve (AUC) and confusion matrices. We further assessed the clinical relevance of the model by visualizing the principal components of features at different layers and through the use of gradient-weighted class activation maps, which presented retinal regions having the most significant influence on the model., Results: Our model was trained, validated, and tested on 1500 fundus images (training, 1200; validation, 150; testing, 150) and achieved an average AUC of 0.98 for identifying the normal, trace (small and local lesions), and disease classes (large and spreading lesions). The AUCs of the model using an independent subset with 180 images were 1.00 (95% confidence interval [CI], 0.99-1.00), 0.97 (95% CI, 0.94-0.99), and 0.96 (95% CI, 0.90-1.00) for the normal, trace and disease classes, respectively., Conclusions: The proposed deep learning model is able to identify three severity levels of EAU with high accuracy. The model also achieved high accuracy on independent validation subsets, reflecting a substantial degree of generalizability., Translational Relevance: The proposed model represents an important new tool for use in animal medical research and provides a step toward clinical uveitis identification in clinical practice., Competing Interests: Disclosure: J.

- Abstract
Purpose : To describe common risk factors in patients with Essential Skin Shrinkage (ESS) and identify corresponding histopathologic changes in lower eyelids. Methods : A case-control study was performed after an Internal Review Board approval was obtained. Consecutive patients who underwent surgical repair for ectropion with ESS of the lower eyelid were enrolled along with 10 control patients. Informed consent was obtained on all patients. Fitzpatrick skin type, history of sun exposure and non-melanoma skin cancer was obtained along with relevant physical exam findings. Skin samples obtained during surgical repair were evaluated by light microscopy for the extent of dermal actinic change. Statistical analysis was performed. Results : Sixteen study subjects and 10 control patients were enrolled. Subjects were found to be predominantly male, older than controls (p = 0.0011) and have Fitzpatrick skin type (FST) I or II while controls had type I, II or III (p = 0.0221). Hours of sun exposure reported by subjects ranged from 23,165 to greater than 125,000 h, versus 1,459 to 46,890 h in controls (p = 0.0002). Nine of 16 (56%) subjects had a history of skin cancer compared to only 3/10 controls (30%) (p = 0.2475). Histopathologic evaluation using the Fritschi scale for dermal actinic damage identified an average grade of 3.6 for subjects and 2.4 for controls (p = 0.0095). Conclusions : ESS is predominantly seen in male individuals with FST I or II and a history of extensive sun exposure. Histopathologic evaluation shows moderate to severe actinic damage. These individuals frequently have concomitant non-melanoma skin cancer.

- Abstract
Background: Thyroid eye disease is a debilitating, disfiguring, and potentially blinding periocular condition for which no Food and Drug Administration-approved medical therapy is available. Strong evidence has implicated the insulin-like growth factor I receptor (IGF-IR) in the pathogenesis of this disease., Methods: In a randomized, double-masked, placebo-controlled, phase 3 multicenter trial, we assigned patients with active thyroid eye disease in a 1:1 ratio to receive intravenous infusions of the IGF-IR inhibitor teprotumumab (10 mg per kilogram of body weight for the first infusion and 20 mg per kilogram for subsequent infusions) or placebo once every 3 weeks for 21 weeks; the last trial visit for this analysis was at week 24. The primary outcome was a proptosis response (a reduction in proptosis of ≥2 mm) at week 24. Prespecified secondary outcomes at week 24 were an overall response (a reduction of ≥2 points in the Clinical Activity Score plus a reduction in proptosis of ≥2 mm), a Clinical Activity Score of 0 or 1 (indicating no or minimal inflammation), the mean change in proptosis across trial visits (from baseline through week 24), a diplopia response (a reduction in diplopia of ≥1 grade), and the mean change in overall score on the Graves' ophthalmopathy-specific quality-of-life (GO-QOL) questionnaire across trial visits (from baseline through week 24; a mean change of ≥6 points is considered clinically meaningful)., Results: A total of 41 patients were assigned to the teprotumumab group and 42 to the placebo group. At week 24, the percentage of patients with a proptosis response was higher with teprotumumab than with placebo (83% [34 patients] vs. 10% [4 patients], P<0.001), with a number needed to treat of 1.36. All secondary outcomes were significantly better with teprotumumab than with placebo, including overall response (78% of patients [32] vs. 7% [3]), Clinical Activity Score of 0 or 1 (59% [24] vs. 21% [9]), the mean change in proptosis (-2.82 mm vs. -0.54 mm), diplopia response (68% [19 of 28] vs. 29% [8 of 28]), and the mean change in GO-QOL overall score (13.79 points vs. 4.43 points) (P≤0.001 for all). Reductions in extraocular muscle, orbital fat volume, or both were observed in 6 patients in the teprotumumab group who underwent orbital imaging. Most adverse events were mild or moderate in severity; two serious events occurred in the teprotumumab group, of which one (an infusion reaction) led to treatment discontinuation., Conclusions: Among patients with active thyroid eye disease, teprotumumab resulted in better outcomes with respect to proptosis, Clinical Activity Score, diplopia, and quality of life than placebo; serious adverse events were uncommon.

- Abstract
Two patients with previously diagnosed pheochromocytoma presented with facial pain and ptosis. Imaging revealed orbital lesions. Both patients were referred for surgical evaluation of the orbital mass. Surgical excision was performed for both. Pathology confirmed metastatic pheochromocytoma. Pheochromocytomas commonly metastasize to bone, liver, and other tissues. Five cases of metastasis to orbital bone have been previously described. These 2 cases are unique in that the metastases were not hormonally active, presented soon after initial diagnosis, and were treated palliatively with surgical excision. Previous treatment of orbital bony metastasis used radiotherapy. These cases demonstrate that surgical resection is a viable treatment option in these situations. Orbital metastasis of pheochromocytomas should be considered with the appropriate clinical presentation. These are the first documented cases of intraorbital metastasis, separate from the bony walls. Previously, orbital bony wall metastases were treated with radiation. Surgical excision is a viable option for treatment of such metastases.Orbital involvement should be considered in patients with systemic disease presenting with new ocular findings.

Phillips ME, Fowler BT, Dryden SC, and Fleming JC
- Abstract
The purpose of this article is to present a modified approach to the reconstruction of the upper and lower eyelids in floppy eyelid syndrome. A retrospective chart review was performed on all floppy eyelid patients who underwent simultaneous tightening of the upper and lower eyelid with a lateral tarsal strip, using a V-shaped incision in the lateral canthus, at University of Tennessee Hamilton Eye Institute from 2011 to 2012. Preoperative symptoms, surgical outcomes, complication rates, and postoperative symptoms were recorded. Nine eyes of 7 patients who underwent surgical correction for symptomatic floppy eyelids were included. All patients noted improvement in symptoms postoperatively, after reduction in the laxity of the upper and lower eyelid. Postoperative complications included buried lashes in the lateral canthus in 1 eye and a pyogenic granuloma in the lateral canthus of 1 eye. An excellent cosmetic outcome was noted in 78% (7/9) of eyes. No patients reported dissatisfaction nor required secondary surgical correction. The lateral canthal "V" incision provides an additional approach in the successful management of floppy eyelid syndrome involving the upper and lower eyelids. The design of the incision allows for excellent exposure of the lateral canthus for shortening of the eyelids with tarsal strip fixation, and it preserves the lateral canthal skin and canthus architecture. Further, the "V" incision is easily continued into the eyelid crease for blepharoplasty and ptosis repair when necessary., (Copyright © 2019 The Authors.

- Abstract
Purpose: To analyze the spontaneous eyelid blink and sphincter closure activity of the orbicularis oculi by measuring the horizontal eyelid movement., Methods: Individuals 18+ years of age, any ethnicity, and gender were recruited. Participants completed a questionnaire to determine eligibility. Exclusion criteria included the following: history of facial trauma, nerve palsy, surgery, use of periorbital neuromodulators or filler within the past year, thyroid eye disease, and eyelid or ocular surface disease. Data were collected from participants by decade. Eyelid blinks were recorded using the FPS 1000HD. The motions of 3 spontaneous blinks in primary gaze were recorded. All blinks were reviewed and one chosen for most accurate analysis. Horizontal palpebral fissure width and its changes of open and closed eye measurements were taken using National Institute of Health ImageJ software version 2.0. The data were subjected to SAS version 9.4 analysis using paired t test, t test, and linear models., Results: One hundred thirty-six patients were recruited. Fourteen patients were excluded; 122 patients were used in analysis. Ages ranged from 22 to 90 years. Participants were divided into 6 groups according to age (20-29, 30-39, 40-49, 50-59, 60-69, and 70+ years of age). The average horizontal fissure length across all ages was 24.23 mm. Average change in horizontal fissure length decreased 1.42 mm among all ages. There was a statistically significant difference comparing age 20-29 decade to age 70+ decade., Conclusions: Horizontal fissure length changes with eyelid blink and defines 1 component of the eyelid sphincter.

- Abstract
To compare post-operative results and complications in patients who undergo enucleation with or without suture closure of the conjunctiva. This was a retrospective chart review study. Review of 50 cases of enucleation surgery at the University of Arkansas for Medical Sciences and Arkansas Children's Hospital between July 2011 and December 2014. Criteria for inclusion in the study were all cases of enucleation that had extraocular muscles attached to a spherical orbital implant with or without conjunctival closure, and at least 2 months of postoperative follow up. Post-operative complications were evaluated. A total of 36 cases fulfilled the criteria for inclusion in the study; 12 cases with direct sutured layered direct closure of Tenon's and then conjunctiva and 24 cases with Tenon's capsule sutured closure but without direct conjunctival sutured closure. No implant complications were identified in either group (p = 1.0). Mean follow-up for all groups was 16.71 months (range 2 to 43 mo., SD 11.94). Mean follow up for the non-closure group was 14.42 months (range 2.25 to 36 mo., SD 10.35). Two cases in the conjunctival closure group developed a conjunctival cyst, affecting prosthesis fit, approximately 3 months postoperatively: no such cysts were identified in the non-conjunctival closure group. Fisher exact test for cyst formation between the two groups was not statistically significant (p = 0.1048). Direct conjunctival closure following enucleation surgery does not appear to increase the risk of extrusion, exposure, or infection. Foregoing direct closure decreases surgical time and reduces cost. It is unclear if this decreases conjunctival cyst formation.

- Abstract
Introduction: Blepharophimosis Syndrome (BPES) is a complex and rare disease characterized by epicanthus inversus, telecanthus, lateral ectropion, narrowed or shortened inter-palpebral fissure distance and ptosis. It is mostly bilateral and may or may not be symmetrical. It is typically inherited as an autosomal dominant trait. In sporadic cases, the disease may occur without a prior family history as a genetic mutation from a deletion or translocation of the FOXL
2 gene, which maps to chromosome 3q23. Surgical treatment of this disease poses an oculoplastic challenge due to multiple complex eyelid deformities., Aim: To evaluate the functional and cosmetic outcome of telecanthus and epicanthus correction by a Mustarde's rectangular double Z-Plasty and trans-nasal fixation using 1-0 prolene suture in BPES., Materials and Methods: This was prospective, interventional study of 16 patients over a period of three years. In this study, all patients had BPES with prominent epicanthus and telecanthus. Mustarde's double Z-plasty and trans-nasal fixation with 1-0 prolene suture was performed in the first of a two-stage operation. If ectropion was present, the lateral ectropion was corrected by a base-out flap transfer from the upper eyelid to the lower eyelid. After three months, a 2nd stage was undertaken, involving a lateral canthoplasty for horizontal widening of a short palpebral fissure and a tarso frontalis sling with silicone rod for correction of moderate to severe ptosis. Patients were followed up for six months to one year with postoperative ophthalmologic examinations and photographs., Results: Out of 16 patients, 10 were females and six were males. All the patients had bilateral involvement. In this study preoperative Inner Intercanthal Distance (IICD) ranged from 38 mm to 42 mm and the mean IICD was 41.2±0.57 mm. Postoperative IICD ranged from 31 mm to 34 mm. Horizontal Palpebral Fissure Length (HPFL) ranged from 20 mm to 23 mm and the mean value of HPFL was 21.50 mm preoperatively. Postoperative HPFL ranged from 26 mm to 29 mm and had a mean value of 28.50 mm, which was much improved after a combined correction of telecanthus and lateral canthoplasty. The mean preoperative IICD and HPFL ratio was 1.77 and was reduced to a postoperative value of 1.2. The Marginal Reflex Distance1 (MRD-1) test value improved from +1.25 mm to +3.50 mm postoperatively after placement of a tarsofrontalis sling with silicone rod using the Fox's Pentagon technique. In this study, two eyes had minimal unequal correction but were cosmetically and functionally acceptable. Correction of IICD is possible up to 6 mm. No major complication e.g., CSF rhinorrhea was noted in this series and preoperative prominent epicanthal folds were abolished., Conclusion: Here we propose a two-staged procedure involving a combined Mustarde's double Z-plasty with transnasal fixation using a 1-0 prolene suture with a flap transfer from the upper lid to the lower lid in the first stage and a lateral canthoplasty with a tarsofrontalis sling and silicone rod in the second stage. This technique is effective to correct epicanthus, telecanthus, ptosis and lateral ectropion in BPES with good cosmetic and functional outcome.- Published

- Abstract
Introduction: Malignant tumour in upper lid is a surgical challenge to oculoplastic surgeon. Full thickness defect created after removal of large tumour promptly treated with modified cutler beard procedure using autogenous auricular cartilage. Surgical procedure is two staged: In first stage, removal of the tumour followed by full thickness flap repaired; In second stage, opening the closed lid with lid margin repair. Post-operatively, there is good anatomical, functional and cosmetic restoration of the eyelid similar to the other eye., Aim: To evaluate the efficacy of the modified Cutler-Beard procedure using autogenous ear cartilage for tarsal plate reconstruction in the repair of 70-100% upper eyelid defects., Materials and Methods: This is a prospective, interventional case series of 16 patients over a period of three years. Patients with upper eyelid defects, secondary to removal of tumour, greater than or equal to 70% were included. Of these patients, those with lymph node involvement, distant metastasis, lower eyelid involvement, corneal infiltration or intra-orbital extension were excluded. FNAC was done in all the cases. Created defect was measured in mm (length and width) and later expressed in percentage. Pre and Post-operative measurement of Levator Palpebrae Superioris (LPS) was done. Pre and Post-operative measurement of Margin to Reflex Distance (MRD1) were also noted., Results: Upper eyelid recreation was successful in all patients without complications. Pre-operative LPS action ranged from 0-4 mm, while post-operative LPS action was 12-14 mm. Pre-operative MRD1 ranged from -4 millimeters to -1 mm, while post-operative MRD1 was +3 to +4 millimeters. The follow-up period ranged from six months to two years. Every patient had a successful upper eyelid reconstruction., Conclusion: The modified Cutler-Beard procedure using an autogenous auricular cartilage graft is an effective procedure for repair of large upper eyelid defects, with acceptable functional and cosmetic results. Furthermore, it is particularly useful in resource-poor areas, due to lower cost than other available options.

- Abstract
Purpose: To assess whether taped versus untaped contrast sensitivity testing reliably predicts improvement following eyelid-lifting surgery in patients with ptosis and/or dermatochalasis., Methods: This prospective study compared pre- and postoperative near contrast sensitivity in patients presenting to 2 ophthalmic plastic surgery practices with functional dermatochalasis and/or ptosis as determined by Humphrey visual field testing. Contrast sensitivity was measured using Mars near cards, held at 40 cm under standard lighting conditions. Logarithmic contrast sensitivity scoring cards were used for analysis. Marginal reflex distance was also collected. Pairwise comparison was used to assess the preoperative and postoperative contrast sensitivity scores. This study was conducted under the approval of the institutional review board., Results: Seventy-eight eyes of 41 patients with ptosis +/ dermatochalasis underwent eyelid-lifting surgery. The mean preoperative untaped contrast sensitivity was 1.30. The mean preoperative taped and postoperative log contrast sensitivities were 1.52 (11.85% increase) and 1.51 (11.44% increase), respectively. The difference between the 2 groups was not statistically significant (p = 0.864). The marginal reflex distance improved by a mean of 2.0 (p < 0.0005)., Conclusions: Contrast sensitivity improves significantly following blepharoplasty and ptosis surgery. The degree of improvement in contrast sensitivity can accurately be predicted by preoperative taped/untaped testing. Contrast sensitivity testing may provide an additional screening modality for functional dermatochalasis and ptosis. In the future, contrast sensitivity may provide an additional preoperative assessment tool in patients who do not meet traditional visual field screening standards or who are unable to perform classic visual field testing.

- Abstract
Purpose: To report the use of punctal plugs as a new modality to assist in the localization of lesions providing symptomatic relief in patients with haemolacria during their workup., Methods: Retrospective case series., Results: One boy and one girl, ages 16 and 20, respectively, reported spontaneous bloody tearing. Workup included probing and irrigation of the nasolacrimal system, blood and coagulation profiles, blood typing, serum hormone levels, conjunctival biopsy, and imaging. All findings were normal and failed to suggest a cause in any of the cases. Punctal plugs were inserted into each patient's inferior punctum OS without complication. On initial follow-up visits, each patient reported cessation of bloody tears OS with continued bloody tears OD. Over time, both patients experienced complete cessation of haemolacria in both eyes., Conclusions: Haemolacria is a condition caused by a group of disorders that result in the production of tears that are partially composed of blood. The large majority of cases result in a specific diagnosis. Only rarely does workup result in undetermined etiology. The novel approach of utilizing punctal plugs in the management of haemolacria may not only provide symptomatic relief for lesions distal to and including the punctum, but also assists in anatomic localization in idiopathic cases.

- Abstract
Purpose: The purpose of this study is to assess the utility of inferior orbital septum release compared with lateral canthotomy and inferior cantholysis for the treatment of orbital compartment syndrome., Method: An experimental study design using a cadaver model for orbital compartment syndrome was used to compare the efficacy of inferior orbital septum release with lateral canthotomy and inferior cantholysis. Elevated orbital compartment pressures were created in a total of 10 orbits of 5 fresh cadaver heads. Compartment pressure and intraocular pressure were measured before and after inferior orbital septum release and lateral canthotomy/cantholysis. Additionally, orbital compartment pressure was compared with intraocular pressure at various pressures to assess correlation. Statistical analysis was performed on the collected data for efficacy comparison of the 2 procedures., Results: Both procedures were found significantly to reduce orbital compartment pressure. Lateral canthotomy and cantholysis was found to lower the pressure by an average of 56 mm Hg as compared with inferior septal release, which resulted in an average of 52-mm Hg reduction. Performing lateral canthotomy and cantholysis first, followed by inferior septal release, resulted in a total pressure reduction of 73 mm Hg, whereas reversing the order resulted in a reduction of 77 mm Hg. Both the first and second steps, regardless of the order of procedure, were found to result in a significant pressure reduction (p = 0.009 and 0.004, respectively). Comparison of a series of data points collected during the induction of the experimental compartment syndrome revealed a statistically significant correlation between orbital compartment pressure and intraocular pressure (Spearman correlation of 0.978 and p value <0.001)., Discussion: The study demonstrates that both lateral canthotomy/cantholysis and inferior orbital septum release are equally effective at reducing orbital compartment pressure. Additionally, the data support an additive, synergistic reduction in compartment pressure when the procedures are performed consecutively. The correlation of orbital compartment pressure to intraocular pressure proves that intraocular pressure can be used as a reliable measurement of orbital pressure during acute changes in orbital mass. The results of this study demonstrate that the use of inferior orbital septum release in conjunction with lateral canthotomy and cantholysis is superior to the gold standard of isolated lateral canthotomy and cantholysis. We hope that the implementation of orbital septum release will result in superior visual outcomes.

- Abstract
We report a case of neutropenia and gram-negative septicemia in a 73-year-old male with ulcerative colitis. During the hospital course, medications were adjusted according to rare accounts of drug-induced neutropenia. While the substitution of propafenone for another antiarrhythmic brought about no change in the patient's absolute neutrophil count, the cessation of Asacol® (Warner Chilcott, Rockaway, NJ) was followed by a significant improvement in the neutropenic state. In fact, this neutrophil count continued to trend upward for months following. We thereby conclude that Asacol® carries the potential to induce neutropenia and that this reaction may be reversed in some patients solely by discontinuing the medication and without the aid of stimulating factors such as filgrastim.

- Abstract
Development is punctuated by morphogenetic rearrangements of epithelial tissues, including detachment of motile cells during epithelial-mesenchymal transition (EMT). Dramatic actin rearrangements occur as cell-cell junctions are dismantled and cells become independently motile during EMT. Characterizing dynamic actin rearrangements and identifying actin machinery driving these rearrangements is essential for understanding basic mechanisms of cell-cell junction remodeling. Using immunofluorescence and live cell imaging of scattering MDCK cells we examine dynamic actin rearrangement events during EMT and demonstrate that zyxin-VASP complexes mediate linkage of dynamic medial actin networks to adherens junction (AJ) membranes. A functional analysis of zyxin in EMT reveals its role in regulating disruption of actin membrane linkages at cell-cell junctions, altering cells' ability to fully detach and migrate independently during EMT. Expression of a constitutively active zyxin mutant results in persistent actin-membrane linkages and cell migration without loss of cell-cell adhesion. We propose zyxin functions in morphogenetic rearrangements, maintaining collective migration by transducing individual cells' movements through AJs, thus preventing the dissociation of individual migratory cells.
