NOVEL MFRP MUTATION WITH NANOPHTHALMOS, OPTIC DISK DRUSEN, AND PERIPHERAL RETINOSCHISIS IMAGED WITH ULTRA-WIDEFIELD OPTICAL COHERENCE TOMOGRAPHY.

PURPOSE: To describe with multimodal imaging including the use of ultra-widefield optical coherence tomography imaging a distinct phenotype of autosomal recessive nanophthalmos associated with a novel mutation of the MFRP gene (membrane-type frizzled-related protein). METHODS: Case report of a single patient followed by the Weill Cornell Medicine Department of Ophthalmology Retina and Glaucoma Services, and review of the relevant literature. RESULTS: A patient with a novel homozygous mutation in the MFRP gene (c.472C>T) presented with nanophthalmos, optic disk drusen, foveal hypoplasia, and extensive peripheral retinoschisis, which was revealed to be multilevel retinoschisis on ultra-widefield optical coherence tomography. Unlike other reported cases, the findings associated with this novel mutation did not include foveoschisis or clinically obvious retinitis pigmentosa. The patient underwent prophylactic peripheral laser iridotomy in both eyes. CONCLUSION: Here, we present a patient with nanophthalmos, optic disk drusen, and foveal hypoplasia associated with extensive peripheral retinoschisis imaged by ultra-widefield optical coherence tomography, but not foveal retinoschisis or prominent retinitis pigmentosa. The findings may expand the clinical spectrum of MFRP -associated nanophthalmos.

The Prevalence of Retinal Disease and Associated CNS Disease in Young Patients with Incontinentia Pigmenti.

PURPOSE: To evaluate the prevalence of retinal disease on fluorescein angiography (FA) in patients with incontinentia pigmenti (IP) and to compare the severity of retinal disease in those with and without known central nervous system (CNS) disease. DESIGN: Multi-institutional consecutive retrospective case series. SUBJECTS: New patients with a diagnosis of IP were seen at the Casey Eye Institute at the Oregon Health and Science University (OHSU), Moran Eye Center, University of Utah, or Bascom Palmer Eye Institute, University of Miami from December 2011 to September 2018. METHODS: Detailed ophthalmoscopic examination and FA were recommended for all new patients and performed on every patient who had parental consent. Ophthalmoscopic findings and FA images were graded for severity by 2 masked graders on a 3-point scale: 0 = no disease, 1 = vascular abnormalities without leakage, 2 = leakage or neovascularization, and 3 = retinal detachment. The presence of known CNS disease was documented. Additional cases were obtained from a pediatric retina listserv for examples of phenotypic variation. MAIN OUTCOME MEASURES: The proportion of eyes noted to have disease on ophthalmoscopy compared with FA and the severity of retinal disease in those with and without known CNS disease. RESULTS: Retinal pathology was detected in 18 of 35 patients (51%) by indirect ophthalmoscopy and 26 of 35 patients (74%) by FA (P = 0.048) in a predominantly pediatric population (median age, 9 months). Ten patients (29%) had known CNS disease at the time of the eye examination. A Wilcoxon rank-sum test indicated that the retinal severity scores for patients with CNS disease (median, 2) were significantly higher than the retinal severity scores for patients without CNS disease (median, 1), z = -2.12, P = 0.034. CONCLUSIONS: Retinal disease is present in the majority of patients with IP, and ophthalmoscopic examination is less sensitive than FA for detection of disease. There may be a correlation between the severity of retinal and CNS disease.

Histopathology of Age-Related Macular Degeneration and Implications for Pathogenesis and Therapy.

Aging is associated with a number of histological changes in the choroid, Bruch's membrane, RPE, and neuroretina. Outside of the normal physiologic aging spectrum of changes, abnormal deposits such as basal laminar deposits, basal linear deposits, and soft drusen are known to be associated with AMD. Progression of AMD to advanced stages involving geographic atrophy, choroidal neovascularization, and/or disciform scars can result in debilitating vision loss. Knowledge of the angiogenic pathway and its components that stimulate neovascularization has led to the development of a new paradigm of intravitreal anti-VEGF pharmacotherapy in the management of neovascular AMD. Currently however, there are no available treatments for the modification of disease progression in non-neovascular AMD, or for the treatment of geographic atrophy. Further understanding of the histopathology of AMD and the molecular mechanisms that contribute to pathogenesis of the disease may reveal additional therapeutic targets.

Ocular Outcomes after Treatment of Cytomegalovirus Retinitis Using Adoptive Immunotherapy with Cytomegalovirus-Specific Cytotoxic T Lymphocytes.

PURPOSE: To describe ocular outcomes in eyes with cytomegalovirus (CMV) retinitis treated with adoptive immunotherapy using systemic administration of CMV-specific cytotoxic Tlymphocytes (CMV-specific CTLs). DESIGN: Retrospective cohort study. PARTICIPANTS: Patients with active CMV retinitis evaluated at a tertiary care academic center. METHODS: Treatment of CMV retinitis with standard-of-care therapy (systemic or intravitreal antivirals) or CMV-specific CTLs (with or without concurrent standard-of-care therapies). MAIN OUTCOME MEASURES: The electronic medical record was reviewed to determine baseline characteristics, treatment course, and ocular outcomes, including best-corrected visual acuity (BCVA), treatments administered (CMV-specific CTLs, systemic antivirals, intravitreal antivirals), resolution of CMV retinitis, any occurrence of immune recovery uveitis, cystoid macular edema, retinal detachment, or a combination thereof. RESULTS: Seven patients (3 of whom had bilateral disease [n = 10 eyes]) were treated with CMV-specific CTLs, whereas 20 patients (6 of whom had bilateral disease [n = 26 eyes]) received standard-of-care treatment. Indications for CMV-specific CTL therapy included persistent or progressive CMV retinitis (71.4% of patients); CMV UL54 or UL97 antiviral resistance mutations (42.9%); side effects or toxicity from antiviral agents (57.1%); patient intolerance to longstanding, frequent antiviral therapy for persistent retinitis (28.6%); or a combination thereof. Two patients (28.6%; 4 eyes [40%]) received CMV-specific CTL therapy without concurrent systemic or intravitreal antiviral therapy for active CMV retinitis, whereas 5 patients (71.4%; 6 eyes [60%]) continued to receive concurrent antiviral therapies. Resolution of CMV retinitis was achieved in 9 eyes (90%) treated with CMV-specific CTLs, with BCVA stabilizing (4 eyes [40%]) or improving (4 eyes [40%]) in 80% of eyes over an average follow-up of 33.4 months. Rates of immune recovery uveitis, new-onset cystoid macular edema, and retinal detachment were 0%, 10% (1 eye), and 20% (2 eyes), respectively. These outcomes compared favorably with a nonrandomized cohort of eyes treated with standard-of-care therapy alone, despite potentially worse baseline characteristics. CONCLUSIONS: CMV-specific CTL therapy may represent a novel monotherapy or adjunctive therapy, or both, for CMV retinitis, especially in eyes that are resistant, refractory, or intolerant of standard-of-care antiviral therapies. More generally, adoptive cell transfer and adoptive immunotherapy may have a role in refractory CMV retinitis. Larger prospective, randomized trials are necessary.

ROLE OF OPTICAL COHERENCE TOMOGRAPHY FOR PREDICTING POSTOPERATIVE VISUAL OUTCOMES AFTER REPAIR OF MACULA-OFF RHEGMATOGENOUS RETINAL DETACHMENT.

PURPOSE: To identify any prognostic associations between preoperative optical coherence tomography findings and postoperative visual outcomes in patients with macula-off rhegmatogenous retinal detachment. METHODS: A retrospective, single-center study of patients diagnosed with macula-off rhegmatogenous retinal detachment whom underwent surgical reattachment from 2012 to 2017. Optical coherence tomography images were analyzed by two retina surgeons. Outcome measures included "good" final vision (best-corrected visual acuity of 20/40 or better), "poor" final vision (best-corrected visual acuity of 20/200 or worse), and change in vision (worsened, improved, and improved ≥15 letters) at most recent follow-up. P values were calculated using t tests, analysis of variance, Wilcoxon rank-sum, or Kruskall-Wallis test. RESULTS: A total of 49 eyes were included. There was a significant difference in the mean preoperative central retinal thickness between patients who had good final vision and patients who did not (96 µm vs. 161 µm, P = 0.048). In addition, a worse preoperative best-corrected visual acuity and greater subretinal fluid height were associated with vision improvement (P < 0.001). Those with persistent ellipsoid zone disruption postoperatively were less likely to have good final vision (odds ratio = 0.217, 95% confidence interval: 0.057-0.828). CONCLUSION: A lower mean preoperative central retinal thickness is associated with good visual prognosis. Eyes with ellipsoid zone disruption postoperatively were less likely to have good final vision. Future studies should include a larger cohort of patients and more optical coherence tomography variables to address the inconsistencies in the current literature.

UNUSUAL EARLY-ONSET VITELLIFORM DYSTROPHY POSSIBLY LINKED TO THE INTERPHOTORECEPTOR MATRIX PROTEOGLYCAN-1 P.LEU154PRO MUTATION.

PURPOSE: To describe a case of symptomatic outer retinal disruption in a patient heterozygous for the p.Leu154Pro interphotoreceptor matrix proteoglycan-1 (IMPG1) mutation implicated in adult-onset foveomacular vitelliform dystrophy. METHODS: Observational case report. RESULTS: We describe a case of a 25-year-old female patient with symptomatic scotoma and vision decrease who exhibited bilateral small foveal yellow spots. Optical coherence tomography revealed disorganization and decreased reflectance of the foveal ellipsoid and interdigitation zones in the left eye more than in the right eye. Fundus autofluorescence imaging showed minimal findings, and dye angiography was unrevealing. Multifocal electroretinogram revealed slightly decreased retinal sensitivity in the central retina of the left eye. Genetic testing identified a heterozygous p.Leu154Pro mutation in the IMPG1 gene. CONCLUSION: The p.Leu154Pro IMPG1 mutation may cause symptomatic outer retinal disturbance in the heterozygous state. Further studies are necessary.

Drug-induced maculopathy.

PURPOSE OF REVIEW: The purpose of this article is to provide an overview of drug-induced maculopathies including their clinical presentations, diagnostic findings, and treatment options. With the increasing pace of development and arrival of drugs to the market, this review aims to inform retina specialists of relevant side effects that may be encountered in a clinical practice setting. RECENT FINDINGS: The major themes visited in this article focus on relevant findings of drugs that cause pigmentary and crystalline maculopathy, photoreceptor dysfunction, cystoid macular edema, central serous choroidopathy, uveitis, and vascular damage. SUMMARY: The current review reports updated findings and discusses the pathophysiologic mechanisms, presentations, and treatments of drug-induced maculopathies.

Retinal manifestations of the neurocutaneous disorders.

PURPOSE OF REVIEW: The neurocutaneous disorders are a genetically and phenotypically diverse group of congenital syndromes characterized by cutaneous, ocular, and central nervous system manifestations. This review provides an overview of the clinical features and retinal findings in selected neurocutaneous disorders. RECENT FINDINGS: Advances in genetics and diagnostic retinal and neuroimaging allow for the recognition of retinal features of common neurocutaneous syndromes and for improved characterization of rarer entities based on previously underdiagnosed or unrecognized retinal findings. SUMMARY: Better characterization of the neurocutaneous disorders allows for earlier recognition and the potential for expeditious vision-saving and life-saving treatment.

Ophthalmology conferences in the coronavirus disease 2019 era.

PURPOSE OF REVIEW: To discuss key considerations involved in adapting an in-person ophthalmology conference to a virtual medium. RECENT FINDINGS: In 2020, several ophthalmological societies have held or are planning to hold virtual conferences in lieu of their previously scheduled in-person ophthalmology conference because of the coronavirus disease 2019 pandemic. The strategic meeting components attempted to be retained in these transitions include educational information disseminating, academic discussion with colleagues, sponsorships, and networking. Live-streamed components of a virtual conference may be entirely real time or may include a combination of both prerecorded and live-streamed components. A virtual meeting may offer either a single live-streamed program or several concurrent live-streamed programs from which attendees can choose. The availability of on-demand content, mechanisms for audience participation, avenues for industry interaction and contribution, registration costs, and continuing medical education credit availability vary between virtual meeting formats. SUMMARY: Transition of an in-person ophthalmology conference to a virtual format with retention of the inherent value associated with the meeting is possible and the experiences of societies executing this adaptation can be helpful for others entering this space. There are numerous considerations regarding meeting format and logistics to contemplate in light of each meeting's specific audience and objectives.

Hypopyon following selective laser trabeculoplasty.

PURPOSE: To report a hypopyon following selective laser trabeculoplasty (SLT). OBSERVATIONS: An 85-year-old woman with primary open-angle glaucoma underwent routine SLT. In the early post-procedural period, she presented with pain and decreased vision, and she was found to have hypopyon, trabeculitis, and corneal edema. The patient was treated with prednisolone acetate and empirically with valacyclovir due to the possibility of herpetic keratouveitis. Work-up for potential etiologies was unrevealing. Her symptoms resolved with treatment, and at eight months follow-up her visual acuity and intraocular pressure had stabilized to her baseline. CONCLUSIONS: Though safe, SLT may be associated with rare adverse events requiring intervention. Hypopyon following SLT is extremely rare, and investigation for causes unrelated to the history of SLT should be undertaken as appropriate. IMPORTANCE: To the best of our knowledge, this is the first report of a hypopyon following SLT in a patient with no history of inflammatory intra-ocular disease.

Evaluation of Potential Systemic Adverse Events Related to Fluorescein Angiography in Pediatric Patients.

PURPOSE: To evaluate adverse events of fluorescein angiography (FA) in pediatric patients. DESIGN: Single-institution retrospective chart review. PARTICIPANTS: Patients 0 to 18 years of age who underwent FA between January 2010 and December 2015 at a single institution in the United States. METHODS: Pediatric patients who underwent FA by 3 surgeons were included in the study. Patients with fewer than 24 hours of documented follow-up were excluded. Significant adverse events within 24 hours of FA were evaluated. Detailed intraoperative and perioperative physiological parameters, including heart rate, blood pressure, oxygen saturation, and ventilation parameters, in inpatients undergoing simultaneous examination under anesthesia were reviewed. Peri-injection effects of FA were evaluated by 2-tailed paired t test comparison of mean 5-minute preinjection and 5-minute postinjection physiological data. MAIN OUTCOME MEASURES: Significant adverse events associated with FA. RESULTS: One hundred fifteen patients with a total of 214 FA examinations were included. No significant adverse events were associated directly with FA. Comparison of mean 5-minute preinjection and postinjection physiologic parameters in 27 patients who underwent intravenous FA during EUA did not reveal significant changes associated with FA. A significant difference was found in average patient age between inpatient (2.5 years) and outpatient (10.7 years) FA (P < 0.00001). The youngest patients who underwent successful FA were 3.8 years old in the outpatient setting and 32 weeks' postmenstrual age in the inpatient setting. Patients younger than 3.8 years accounted for most (77.6%; n = 85) inpatient FA examinations. Excluding patients with a need or likely need for laser or surgery, the reasons for inpatient FA in patients older than 3.8 years included the lack of availability of outpatient ultra-widefield FA (UWFA) and more challenging situations in patients with developmental delay. CONCLUSIONS: Fluorescein angiography was not found to be associated directly with systemic adverse events in pediatric patients in this study. Younger patients more commonly were found to require an inpatient FA, whereas older patients older than 4 years underwent outpatient UWFA.

Placoid choroidopathy after bilateral uncomplicated descemet's membrane endothelial keratoplasty.

PURPOSE: To describe a case of bilateral, sequential placoid choroidopathy following uncomplicated Descemet's membrane endothelial keratoplasty (DMEK). OBSERVATIONS: A 49-year old woman presented with flashing lights and central visual field scotomas after undergoing uncomplicated DMEK combined with cataract surgery for Fuch's endothelial dystrophy in the right eye. She was found to have placoid choroidopathy responsive to systemic steroids and for which a comprehensive work-up was unrevealing. Three and a half months later, she underwent DMEK surgery in the fellow eye and again developed placoid choroidopathy in the operated eye. Work-up was again unrevealing and the lesion followed a similar course to the first eye on systemic steroids. Over the course of seven (right eye) and three and a half months (left eye) of follow-up, the uncorrected visual acuity was 20/20 bilaterally and the retinal lesions had modestly improved. CONCLUSIONS AND IMPORTANCE: We report a case of placoid choroidopathy following uncomplicated DMEK combined with cataract surgery in both eyes of a single patient. This case expands upon the reported complications following DMEK surgery and suggests a need to remain aware of posterior segment complications following endothelial keratoplasty.

Late-Onset Retinal Findings and Complications in Untreated Retinopathy of Prematurity.

PURPOSE: To investigate late retinal findings and complications of eyes with a history of retinopathy of prematurity (ROP) that did not meet treatment criteria and did not receive treatment during infancy. DESIGN: Retrospective, nonconsecutive, noncomparative, multicenter case series. PARTICIPANTS: Three hundred sixty-three eyes of 186 patients. METHODS: Data were requested from multiple providers on premature patients with a history of ROP and no treatment during infancy who demonstrated late retinal findings or complications and included age, gender, gestational age and weight, zone and stage at infancy, visual acuity, current retina vascularization status, vitreous character, presence of peripheral retinal findings such as lattice retinal tears and detachments (RDs), retinoschisis, and fluorescein findings. MAIN OUTCOME MEASURES: Rate of RDs and factors conferring a higher risk of RDs. RESULTS: The average age was 34.5 years (range, 7-76 years), average gestational age was 26.6 weeks (range, 23-34 weeks), and average birth weight was 875 g (range, 425-1590 g). Findings included lattice in 196 eyes (54.0%), atrophic holes in 126 eyes (34.7%), retinal tears in 111 eyes (30.6%), RDs in 140 eyes (38.6 %), tractional retinoschisis in 44 eyes (11.9%), and visible vitreous condensation ridge-like interface in 112 eyes (30.5%). Fluorescein angiography (FA) was performed in 113 eyes, of which 59 eyes (52.2%) showed leakage and 16 eyes (14.2%) showed neovascularization. Incomplete vascularization posterior to zone 3 was common (71.6% of eyes). Retinal detachments were more likely in patients with a gestational age of 29 weeks or less (P < 0.05) and in eyes with furthest vascularization to posterior zone 2 eyes compared with zone 3 eyes (P = 0.009). CONCLUSIONS: Eyes with ROP not meeting the treatment threshold during infancy showed various late retinal findings and complications, of which RDs were the most concerning. Complications were seen in all age groups, including patients born after the Early Treatment for Retinopathy of Prematurity Study. Contributing factors to RDs included atrophic holes within peripheral avascular retina, visible vitreous condensation ridge-like interface with residual traction, and premature vitreous syneresis. We recommend regular examinations and consideration of ultra-widefield FA examinations. Prospective studies are needed to explore the frequency of complications and benefit of prophylactic treatment and if eyes treated with anti-vascular endothelial growth factor therapy are at risk of similar findings and complications.

Non-reversible tissue fixation retains extracellular vesicles for in situ imaging.

Extracellular vesicles (EVs) are secreted nanosized particles with many biological functions and pathological associations. The inability to image EVs in fixed tissues has been a major limitation to understanding their role in healthy and diseased tissue microenvironments. Here, we show that crosslinking mammalian tissues with formaldehyde results in significant EV loss, which can be prevented by additional fixation with 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide (EDC) for visualization of EVs in a range of normal and cancer tissues.

Ultra-Widefield Autofluorescence Imaging of Retinal Detachment Compared to Retinoschisis.

BACKGROUND AND OBJECTIVE: Localized retinal detachment can appear similar to peripheral retinoschisis (RS) based on clinical exam alone. This study utilized ultra-widefield autofluorescence (UAF) to characterize retinal changes in patients with rhegmatogenous retinal detachment (RRD) compared to RS and to help differentiate these two entities in the era of multimodal imaging. PATIENTS AND METHODS: A retrospective review of 282 eyes undergoing diagnostic UAF. Eyes were excluded if the quality of the color photograph or UAF prevented reliable evaluation, or if they contained significant peripheral retinal pathology such as diabetic retinopathy or retinal vein occlusions. Eyes were determined to have RRD or RS based on dilated fundus examination, ultrasound, and optical coherence tomography imaging consistent with the diagnosis. RESULTS: Fifty-three eyes were included; 38 had retinal detachment, and 25 had RS. Eyes were determined to be bullous or not from the color photographs. Based on all UAFs reviewed, images were determined to have granular, normal, hypo-, hyper-, or mixed autofluorescence patterns. The posterior border of the RRD and RS was evaluated separately and determined to have hyper-, hypo-, granular, mixed, or normal autofluorescence. Thirty-three eyes with RRD (86.8%) appeared bullous compared to 12 eyes with RS (48%; P = .002). UAF was considered granular in zero (0%) of RRD eyes and one (4%) RS eye, normal in one RRD eye (2.63%) and 17 (68%) RS eyes, hypoautofluorescent in 27 (71.1%) RRD eyes and four (16%) RS eyes, hyperautofluorescent in one (2.63%) RRD eye and one (4%) RS eye, and mixed in nine (4%) RRD eyes and two (8%) RS eyes (P < .001). When evaluating the posterior leading edge on UAF, 84.2% (n = 32) of patients with RRD had a hyperautofluorescent leading edge compared to 25% (n = 6) of patients with RS (P < .001). UAF was homogenous in 65.8% (n = 25) of cases of RRD versus in 92% (n = 23) of cases of RS (P = .037). CONCLUSIONS: To the authors' knowledge, this is the first study to utilize UAF imaging to differentiate RRD and RS. Findings suggest there are differences between RRD and RS with regards to UAF, UAF of the posterior border, and homogeneity of the area affected. UAF should be considered in the era of multimodal imaging, particularly when clinical exam alone is inadequate to differentiate these two entities.

Comorbid hepatitis C does not modulate prevalence or severity of diabetic retinopathy.

PURPOSE: There are limited and conflicting data regarding the impact of comorbid hepatitis C virus (HCV) infection on diabetic retinopathy (DR). This study sought to compare the prevalence and severity of DR among patients with diabetes mellitus (DM) with and without HCV. PATIENTS AND METHODS: This was a retrospective, case-control study of patients with DM comparing 120 patients with comorbid HCV and 120 age-matched controls. DR prevalence and several measures of severity were compared between groups. Subgroup analyses were performed among HCV patients with cirrhosis, comorbid HIV, or history of treatment with interferon. Statistical analysis for between-group comparisons utilized both univariate and multivariate analyses. RESULTS: Cases and controls exhibited similar baseline characteristics: average hemoglobin A1c, DM duration, and age (p>0.05). Among cases and controls, there was no difference in DR prevalence (35.8% versus 42.5%, respectively, p=0.29) or severity (p>0.05). Within the HCV subgroup, DR severity was reduced in patients with HIV or cirrhosis. However, multivariate analysis identified reduced DM duration in these subgroups as the primary contributor to lesser DR severity, rather than HIV or cirrhosis. CONCLUSION: In this study, comorbid HCV did not modulate the prevalence or severity of DR among patients with DM. These findings may inform clinical monitoring among HCV-positive diabetics undergoing ophthalmic evaluation.

Assessing the value of preoperative medical clearance in patients with primary rhegmatogenous retinal detachment.

PURPOSE: To determine rates of intraoperative and postoperative systemic and ocular adverse events and establish the value of preoperative medical assessment in patients undergoing surgery for primary rhegmatogenous retinal detachment repair at a single academic center. PATIENTS AND METHODS: Retrospective cohort study of 185 patients undergoing surgery for repair of primary rhegmatogenous retinal detachment (RRD) at a single academic center. Medical records were reviewed for medical comorbidities, completion of preoperative medical examination, anesthesia used during surgery, intraoperative adverse medical events, intraoperative ocular complications, and systemic and ocular postoperative complications. The main outcome of interest was the association of comorbidities and preoperative medical evaluation with intraoperative and postoperative complications. RESULTS: Approximately 48% of the patients presented with no medical comorbidities of interest. Formal preoperative evaluation by an independent medical provider was completed in 36% of the patients. Overall, intraoperative and postoperative systemic complications (5.7% and 1%, respectively) and intraoperative and postoperative ocular complications (0.5% for both) were uncommon. Patients with a history of chronic heart failure (OR 24.5, P=0.02) or who received general anesthesia (OR 9.56, P<0.001) had increased risk of having experienced any intraoperative or postoperative complication. No relationship between preoperative medical evaluation and intraoperative and postoperative complications was observed. CONCLUSION: Patients undergoing surgery for RRD repair presented with fewer medical comorbidities than previously reported in patients undergoing all vitreoretinal surgeries. Intraoperative and postoperative complications were uncommon and were increased in patients with chronic heart failure or who received general anesthesia. Complications were not significantly associated with preoperative evaluation by an independent medical provider.

Early Diagnosis and Management of Aggressive Posterior Vitreoretinopathy Presenting in Premature Neonates.

BACKGROUND AND OBJECTIVE: Aggressive posterior vitreoretinopathy (APVR) manifests with a broad area of retinal avascularity, progressive neovascularization, and/or tractional retinal detachment during the neonatal period. PATIENTS AND METHODS: A multicenter, retrospective, observational, consecutive case series study was performed to evaluate the retinal findings and structural retinal outcomes in patients treated for APVR within the first 3 months of life. RESULTS: Three premature neonates with a non-retinopathy of prematurity (ROP) APVR identified during routine ROP screening exams exhibited relatively severe, rapidly progressive retinal vascular abnormalities. Immediate laser photocoagulation of the avascular retina and vitrectomy for traction retinal detachment within several days to weeks improved or stabilized the retinal anatomy in all cases. CONCLUSIONS: This series describes clinical features in APVR in premature infants and suggests that early diagnosis and intervention may mitigate the typical aggressive course and poor prognosis of this condition.

Longitudinal Examination of Fellow-Eye Vascular Anomalies in Coats' Disease With Widefield Fluorescein Angiography: A Multicenter Study.

BACKGROUND AND OBJECTIVE: Retinovascular anomalies in the fellow eyes of patients with Coats' disease have been described, but the clinical significance is unknown, as well as whether these lesions progress over time. PATIENTS AND METHODS: This is an international, multicenter, retrospective, observational cohort study of fellow-eye abnormalities on widefield fluorescein angiography in patients with Coats' disease. RESULTS: Three hundred fifty eyes of 175 patients with Coats' disease were analyzed. A total of 33 patients (18.8%) demonstrated abnormal fellow-eye findings: 14 (42.4%) telangiectasias, 18 (54.5%) aneurysms, six (18.2%) segmental non-perfusion, six (18.2%) leakage, and two (6.0%) vascular tortuosity. All eyes were asymptomatic, and none of the lesions progressed over time. There was no association between fellow-eye findings with severity of Coats' disease (P = .16), patient age (P = .16), or presence of systemic vascular disease (P = .16). CONCLUSIONS: The vascular abnormalities in fellow eyes of patients with Coats' disease did not progress over time. Observation is a reasonable initial management strategy.
