Resolution of Postoperative Cystoid Macular Edema with a Suprachoroidal Triamcinolone Acetonide Injectable Suspension.

AIM: To report a case of significant postoperative cystoid macular edema (CME) in a patient with no prior history of uveitis or systemic inflammatory disease, in which a suprachoroidal (SC) triamcinolone acetonide injectable suspension resulted in complete resolution of CME. DESIGN: Case report. METHODS: An 81-year-old man presented with a complex, dense brunescent cataract, floppy iris, and miotic pupil in the left eye. Six weeks following cataract extraction, the intraocular lens (IOL) was dislocated completely from the visual axis. He underwent a pars plana vitrectomy and IOL exchange with an anterior chamber IOL due to a three-piece IOL dislocation. Following the operation, the patient began treatment with prednisolone acetate and ketorolac. However, 2 weeks later, he was noted to be a steroid responder and glaucoma suspect. Therefore, the decision was made to taper and discontinue topical steroids. At 6 months postoperatively, ranibizumab was injected for persistent CME. However, following injection, there was intraocular pressure (IOP) elevation and increased CME. IOP improved 1 month later with dorzolamide hydrochloride and timolol maleate. At 8 months post-operation, there was persistent CME. The patient was then treated with an SC triamcinolone acetonide injection. There was complete resolution of CME by 14 weeks later, with improvement in visual acuity. Despite the patient's known steroid response with topical steroids, IOP remained within normal limits during the entire follow-up period after injection. CONCLUSION: SC triamcinolone acetonide injection is indicated for macular edema associated with uveitis; however, treatment for postoperative macular edema with this novel suprachoroidal injection may be considered.

High Rates of Eye Surgery Cancellation in Veterans Related to Mental Health.

INTRODUCTION: Approximately 9 million veterans receive health care at the Veterans Health Administration, many of whom have psychiatric illnesses. The military continues to have higher rates of psychiatric illness compared to the civilian population. Having a diagnosis such as posttraumatic stress disorder or depression may create challenges in using health care services, such as surgery. The aim of this study was to evaluate eye surgery cancellation, risk factors for cancellation, and areas for intervention within the VA. MATERIALS AND METHODS: This was a single-center retrospective cohort study. The Veteran Health Information Systems and Technology Architecture were queried to identify all surgical requests at the West Los Angeles VA in 2019. Data collection included sociodemographic information and comorbid medical conditions, including psychiatric illness. Exploratory analyses using univariate logistic regression were used to evaluate factors associated with surgery cancellation. RESULTS: A total of 1,115 surgical requests were identified with a cancellation rate of 23.7% (n = 270). Sociodemographic factors were similar between those with completed and cancelled surgery. However, having a psychiatric diagnosis correlated with surgery cancellation. For all subspecialties, patients with schizophrenia were more likely to have cancellation (odds ratio [OR], 2.53, P = .04). For retina surgery, patients with posttraumatic stress disorder were more likely to have cancellation (OR, 4.23, P = .01). Glaucoma patients with anxiety (OR, 5.78, P = .05) and depression (OR, 4.05, P = .04) were more likely to have cancellation. CONCLUSIONS: There was a significant amount of eye surgery cancellations in veterans with variation by subspecialty and comorbid conditions. Having a psychiatric illness was correlated with increased rates of surgery cancellation amongst veterans. Areas to improve surgical utilization include risk stratification and increased support of vulnerable patients before surgery.

Familial Exudative Vitreoretinopathy Initially Diagnosed as Incontinentia Pigmenti in an Asymptomatic Teenager: A Case Report.

In this case report, we aim to illustrate a presentation of familial exudative vitreoretinopathy (FEVR) that closely resembles incontinentia pigmenti (IP) and the role of genetic testing that is of no cost to the patient in providing the correct diagnosis. We present a case of an 11-year-old female-to-male transgender patient with a history of hypodontia and skin hypopigmentation who was incidentally found to have a retinal lesion on ultra-widefield fundus imaging during routine screening. Ultra-widefield fluorescein angiography confirmed bilateral peripheral ischemic retinopathy that was successfully treated with laser. The patient was presumed to have IP; however, genetic testing was negative. Due to cost, further genetic testing was declined by the family, and the patient had no further ocular complaints. At age 16, genetic testing became available to the patient, and the patient was found to have FEVR with LRP5 mutation. The patient began screening for comorbidities associated with LRP5 mutation. This case highlights how the ophthalmologic findings of FEVR can present identically to those of IP, and genetic testing is an invaluable tool in distinguishing between these two pathologies. Correct diagnosis of FEVR is vital in assessing other comorbidities of the disease, including osteoporosis. Furthermore, increased use of ultra-widefield fundus imaging in routine eye screening may be of great benefit for community screening of retinal disease, and ultra-widefield fluorescein angiography is of significant use in the diagnosis of FEVR.

Neurodevelopmental Outcomes in Infants Screened for Retinopathy of Prematurity.

Importance: Preterm infants screened for retinopathy of prematurity (ROP) are at risk for heterogenous neurodevelopment outcomes that are difficult to predict. Objective: To characterize the potential association between socioeconomic and clinical risk factors and neurodevelopmental outcomes in a diverse, multicenter cohort of premature neonates screened for ROP. Design, Setting, and Participants: This was a retrospective cohort study using electronic medical records and US Census Bureau income data. This study was performed at academic (University of California, Los Angeles [UCLA] Mattel Children's Hospital and UCLA Santa Monica Hospital), community (Cedars-Sinai Medical Center), and LA county (Harbor-UCLA Medical Center) neonatal intensive care units. Participants included infants who met American Academy of Pediatrics guidelines for ROP screening and had records from at least 1 Bayley Scales of Infant and Toddler Development (BSID) neurodevelopment assessment between 0 and 36 months of adjusted age. Data analyses were conducted from January 1, 2011, to September 1, 2022. Exposures: Demographic and clinical information, proxy household income, and health insurance type were collected as risk factors. Main Outcomes and Measures: Neurodevelopmental outcomes in the cognitive, language, and motor domains measured via BSID were the primary outcomes. Results: A total of 706 infants (mean [SD] age, 28.6 [2.4] weeks; 375 male [53.1%]) met inclusion criteria. In a multivariable model, which included adjustments for birth weight, sex, insurance type, intraventricular hemorrhage (IVH), and age at assessment, public health insurance was associated with a 4-fold increased risk of moderate to severe neurodevelopmental impairment (NDI) in cognitive and language domains (cognitive, odds ratio [OR], 3.65; 95% CI, 2.28-5.86; P = 8.1 × 10-8; language, OR, 3.96; 95% CI, 2.61-6.02; P = 1.0 × 10-10) and a 3-fold increased risk in the motor domain (motor, OR, 2.60; 95% CI, 1.59-4.24; P = 1.4 × 10-4). In this adjusted model, clinical factors that were associated with an increased risk of moderate to severe NDI included lower birth weight, diagnosis of IVH, male sex, and older age at time of Bayley assessment. In unadjusted analyses, infants who received either laser or anti-VEGF treatment, compared with infants without treatment-requiring ROP, had lower BSID scores in multiple domains at 0 to 12 months, 12 to 24 months, and 24 to 36 months (DATA). In the multivariable model, treatment type was no longer associated with worse neurodevelopmental outcomes in any domain. Conclusions and Relevance: Study results suggest an association between public insurance type and NDI in a diverse population screened for ROP, indicating the complexities of neurodevelopment. This study also supports the early neurodevelopmental safety of anti-VEGF treatment, as anti-VEGF therapy was not found to be independently associated with worse NDI in any domain.

The relationship of diabetic retinopathy severity scales with frequency and surface area of diabetic retinopathy lesions.

PURPOSE: To assess the relationship between qualitative diabetic retinopathy (DR) scales with the precise numbers and surface area of DR lesions within the Early Treatment Diabetic Retinopathy Study (ETDRS) standard seven field (S7F) region on ultrawide-field (UWF) color fundus images. METHODS: In this study, we collected UWF images from adult patients with diabetes. Poor-quality images and eyes with any pathology precluding assessment of DR severity were excluded. The DR lesions were manually segmented. DR severity was graded according to the International Clinical Diabetic Retinopathy (ICDR) and AA protocol by two masked graders within the ETDRS S7F. These lesions' numbers and surface area were computed and correlated against the DR scores using the Kruskal-Wallis H test. Cohen's Kappa was performed to determine the agreement between two graders. RESULTS: One thousand five hundred and twenty eyes of 869 patients (294 females, 756 right eyes) with a mean age of 58.7 years were included. 47.4% were graded as no DR, 2.2% as mild non-proliferative DR (NPDR), 24.0% as moderate NPDR, 6.3% as severe NPDR, and 20.1% as proliferative DR (PDR). The area and number of DR lesions generally increased as the ICDR level increased up to severe NPDR, but decreased from severe NPDR to PDR. There was perfect intergrader agreement on the DR severity. CONCLUSION: A quantitative approach reveals that DR lesions' number and area generally correlate with ICDR-based categorical DR severity levels with an increasing trend in the number and area of DR lesions from mild to severe NPDR and a decrease from severe NPDR to PDR.

A MULTICENTER STUDY OF RETINOPATHY OF PREMATURITY FOLLOW-UP ADHERENCE.

PURPOSE: Characterize clinical and socioeconomic factors that impact follow-up to complete retinal vascularization and subsequent pediatric ophthalmology follow-up in neonates with retinopathy of prematurity. METHODS: Medical records of 402 neonates diagnosed with retinopathy of prematurity from neonatal intensive care units at the University of California, Los Angeles Mattel Children's Hospital and the University of California, Los Angeles Santa Monica Hospital, both academic medical centers, and the Harbor-University of California, Los Angeles Medical Center, a safety-net county hospital, were reviewed. Primary study outcomes were the rate of follow-up to complete retinal vascularization and adequate pediatric ophthalmology follow-up. Secondary outcome was the rate of nonretinal ocular comorbidity. RESULTS: In whole-cohort analysis, 93.6% of neonates were followed to complete retinal vascularization, and 53.5% had adequate pediatric ophthalmology follow-up. Public insurance was associated with lower rates of pediatric ophthalmology follow-up (Odds ratio 0.66, 95% confidence interval 0.45-0.98, P = 0.04). Participants screened at the academic medical center had lower rates of pediatric ophthalmology follow-up compared with the safety-net county hospital (50.7% vs. 63.5%, P = 0.034). In subgroup analysis, academic medical center participants with public insurance were less likely to have pediatric ophthalmology follow-up than safety-net county hospital participants with public insurance (36.5% vs. 63.8%, P < 0.001) or those with private insurance at the academic medical center (36.5% vs. 59.2%, P< 0.001). CONCLUSION: This study identified high follow-up rates to complete retinal vascularization, lower pediatric ophthalmology follow-up rates, and nonretinal ocular comorbidity at all hospitals. Insurance status relative to hospital type was identified as a risk factor for loss to follow-up. This demonstrates a need to further study health care disparities in retinopathy of prematurity infants.

Differential Susceptibility of Fetal Retinal Pigment Epithelial Cells, hiPSC- Retinal Stem Cells, and Retinal Organoids to Zika Virus Infection.

Zika virus (ZIKV) causes microcephaly and congenital eye disease. The cellular and molecular basis of congenital ZIKV infection are not well understood. Here, we utilized a biologically relevant cell-based system of human fetal retinal pigment epithelial cells (FRPEs), hiPSC-derived retinal stem cells (iRSCs), and retinal organoids to investigate ZIKV-mediated ocular cell injury processes. Our data show that FRPEs were highly susceptible to ZIKV infection exhibiting increased apoptosis, whereas iRSCs showed reduced susceptibility. Detailed transcriptomics and proteomics analyses of infected FRPEs were performed. Nucleoside analogue drug treatment inhibited ZIKV replication. Retinal organoids were susceptible to ZIKV infection. The Asian genotype ZIKV exhibited higher infectivity, induced profound inflammatory response, and dysregulated transcription factors involved in retinal organoid differentiation. Collectively, our study shows that ZIKV affects ocular cells at different developmental stages resulting in cellular injury and death, further providing molecular insight into the pathogenesis of congenital eye disease.

Rhegmatogenous retinal detachment after retinopathy of prematurity laser treatment.

Purpose: Rhegmatogenous retinal detachment (RRD) after retinopathy of prematurity (ROP) laser is rare but has been reported to occur at the border of heavy laser or in combination with tractional retinal detachment (TRD). We describe a rare case of a RRD that developed during treatment for ROP with both laser and intravitreal injections. Observations: The retinal detachment resolved with scleral buckling surgery with residual macular atrophy. Conclusions and Importance: This case highlights the importance of retinal imaging, careful funduscopic examination, and consideration of the risk of RRDs after intravitreal injections and laser in neonates with ROP.

PRENATAL MATERNAL CHARACTERISTICS ASSOCIATED WITH RETINOPATHY OF PREMATURITY.

PURPOSE: Determine whether prenatal maternal characteristics such as sociodemographic characteristics, comorbidities, or pregnancy complications affect retinopathy of prematurity (ROP) development. METHODS: Medical records of 236 mother-infant dyads from our institution were reviewed, only including dyads in which infants were born at 30 weeks gestational age or earlier. The primary outcome measure was the risk of ROP (defined Stage 1 or greater in either eye) and its association with prenatal maternal variables. RESULTS: Maternal Medicaid insurance, smoking during pregnancy, and chorioamnionitis were associated with an increased risk of ROP. For Medicaid insurance and chorioamnionitis, these risks were not appreciably altered by adjustment for potential confounders. CONCLUSION: These results suggest that several prenatal maternal factors may independently affect the risk of ROP in preterm infants. Validation of our findings could aid in the identification of infants at high risk for ROP based on prenatal clinical features.

Ethnic Variation in Diabetic Retinopathy Lesion Distribution on Ultra-widefield Imaging.

PURPOSE: To evaluate whether the distribution of diabetic retinopathy (DR) lesions differs among various ethnicities. DESIGN: Multi-center, retrospective cohort study. METHODS: We accrued a cohort of 226 eyes with DR consisting of 51 East Asian eyes, 102 South Asian eyes, 30 Caucasian eyes, and 43 Latino eyes, all evaluated with ultrawide field pseudocolor images. Images were manually annotated for DR lesions and were classified as having predominantly peripheral lesions (PPL) or predominantly central lesions (PCL) using 4 quantitative methods. The percent distribution of PCL to PPL was compared among different ethnicities. RESULTS: Using a single-field lesion frequency-based method, East Asian eyes more frequently demonstrated a PPL distribution (86.3%), whereas South Asian eyes more frequently demonstrated a PCL distribution (64.7%). These findings were also observed when considering only the subset of treatment-naïve eyes. Furthermore, in treatment-naïve eyes without proliferative DR, the percent distribution of PPL to PCL in East Asian eyes was significantly different when compared to other ethnicities (P < .0001 South Asian, P = .035 Caucasian, P = .0003 Latino). The majority of patients (60%-78%) in all ethnic groups had moderate nonproliferative diabetic retinopathy(NPDR), and the same difference between East Asian and South Asian eyes was observed in this subgroup. CONCLUSIONS: The distribution of DR lesions appears to vary among different ethnicities. DR lesions tend to be distributed more peripherally in East Asian eyes compared to other ethnic groups, particularly South Asian eyes, which tend to have more central disease. The prognostic implications of these ethnic differences in DR lesion distribution require further investigation.

Decreased Levels of Erythrocyte Membrane Arachidonic and Docosahexaenoic Acids Are Associated With Retinopathy of Prematurity.

Purpose: Retinopathy of prematurity (ROP) can lead to blindness. Arachidonic acid (ARA) and docosahexaenoic acid (DHA) regulate retinal inflammation and angiogenesis. The aim of this study was to investigate red blood cell membrane (RBCM) ARA and DHA in preterm infants. Methods: This prospective observational study divided infants into groups by ROP severity and RBCM ARA and DHA means and terciles. Results: Although the mean ± SD RBCM ARA was different between groups (no ROP, 17.9% ± 0.7%, vs. type 2 ROP, 17.4% ± 0.8%, vs. type 1 ROP, 16.7% ± 1.0%; P < 0.001), the mean RBCM DHA was similar (P = 0.161). Infants with type 1 ROP were more likely to be in the lowest ARA and DHA terciles than in the highest (ARA, 44% vs. 5.6%; DHA, 22% vs. 5.6%). ARA and DHA declined over the first month of life in all ROP groups. At week 1, ARA was lower in the type 1 and type 2 ROP groups compared with the no-ROP group (18% ± 2% and 19% ± 3% vs. 21% ± 2%, respectively; P < 0.05 for all). At week 2, DHA and ARA were lower in the type I ROP group compared with the no-ROP group (3% ± 1% vs. 4% ± 1%, P = 0.03 and 16% ± 1% vs. 19% ± 1%, respectively; P < 0.01). A RBCM ARA% ≥ 17 was associated with a 45% reduction in any ROP. As the estimated 4-week ARA% mean increased by 1%, the odds of ROP decreased by 70% (odds ratio = 0.30; 95% confidence interval, 0.1-0.7). Conclusions: Infants with severe ROP have lower ARA and DHA levels than infants without ROP. ARA and DHA may act synergistically to protect against ROP.

Epithelial membrane protein 2 (EMP2) regulates hypoxia-induced angiogenesis in the adult retinal pigment epithelial cell lines.

Pathologic retinal neovascularization is a potentially blinding consequence seen in many common diseases including diabetic retinopathy, retinopathy of prematurity, and retinal vaso-occlusive diseases. This study investigates epithelial membrane protein 2 (EMP2) and its role as a possible modulator of angiogenesis in human retinal pigment epithelium (RPE) under hypoxic conditions. To study its effects, the RPE cell line ARPE-19 was genetically modified to either overexpress EMP2 or knock down its levels, and RNA sequencing and western blot analysis was performed to confirm the changes in expression at the RNA and protein level, respectively. Protein expression was evaluated under both normoxic conditions or hypoxic stress. Capillary tube formation assays with human umbilical vein endothelial cells (HUVEC) were used to evaluate functional responses. EMP2 expression was found to positively correlate with expression of pro-angiogenic factors HIF1α and VEGF at both mRNA and protein levels under hypoxic conditions. Mechanistically, EMP2 stabilized HIF1α expression through downregulation of von Hippel Lindau protein (pVHL). EMP2 mediated changes in ARPE-19 cells were also found to alter the secretion of a paracrine factor(s) in conditioned media that can regulate HUVEC migration and capillary tube formation in in vitro functional angiogenesis assays. This study identifies EMP2 as a potential mediator of angiogenesis in a human RPE cell line. EMP2 levels positively correlate with pro-angiogenic mediators HIF1α and VEGF, and mechanistically, EMP2 regulates HIF1α through downregulation of pVHL. This study supports further investigation of EMP2 as a promising novel target for therapeutic treatment of pathologic neovascularization in the retina.

Effects of COVID-19 on Intravitreal Injection Clinic After Lockdown.

Purpose: To examine the return of patients to intravitreal injection clinic after the COVID-19 lockdown. Patients and Methods: The electronic medical records of all patients who received intravitreal injections at a tertiary care Veterans Health Administration (VHA) clinic 14 weeks post-lockdown (5/9/20-8/13/20) in Los Angeles County were reviewed. Reference groups included injection patients during the 7-week COVID-19 lockdown (3/19/20-5/8/20) and a 7-week pre-pandemic period in 2019 (3/19/19-5/8/19). Clinic volume was compared using a one-way ANOVA. Demographic data, medical and psychiatric co-morbidities, injection diagnoses, visual acuities, and clinic volumes were compared between the 3 periods using a generalized estimating equation multivariate analysis. Results: The post-lockdown period group averaged 25.1 visits per week, compared with 12.3/week during lockdown and 25.4/week pre-COVID in intravitreal injection clinic. In the post-lockdown period, the VHA injection clinic returned closer to the pre-lockdown volume compared to the VHA comprehensive clinic (98.9% vs 57.4%, p < 0.001). Post-lockdown, COPD patients and organ transplant patients were less likely to receive injections compared to 2019 (OR 0.76 p = 0.008, OR 1.37 p < 0.0001, respectively). Patients with a diagnosis of cancer increased in proportion between the pre-pandemic and the post-lockdown periods (OR 1.31, p = 0.007). No differences were found, according to psychiatric co-morbidities. After lockdown, the proportion of patients receiving injections for diabetic macular edema (DME) increased (OR 1.11, p = 0.01). Conclusion: Injection volume returned to pre-pandemic levels immediately after lockdown ended. However, patients with high-risk comorbidities did not return to intravitreal injection clinic post-lockdown. These results can inform medical organizations, which groups may need increased safety measures and targeted outreach to address their ophthalmic needs.

Findings on Optical Coherence Tomography in Malignant Infantile Osteopetrosis.

Malignant infantile osteopetrosis is a rare inherited disorder with neurological complications and a shortened life expectancy. Vision loss is typically attributed to osseous compression of the optic nerves at the level of the optic canal. Fundus imaging is reported, as well as the first optical coherence tomography and optical coherence tomography angiography in this rare condition. Imaging revealed optic nerve pallor, subfoveal ellipsoid zone disruption, and an enlarged foveal avascular zone. These results provide insight regarding other potential mechanisms of vision loss in these patients. [Ophthalmic Surg Lasers Imaging Retina 2022; 53:398-402.].

Characterization of Foveal Development in Treatment-Naïve Extremely Preterm Infants.

Objective: To characterize and quantify foveal development in treatment-naïve extremely preterm infants using optical coherence tomography. Methods: In this cross-sectional study, eyes treated for retinopathy of prematurity before imaging were excluded. Inner retinal thickness and outer retina thickness at foveal center and foveal rim were assessed. Extremely preterm (EPT, <28 weeks gestational age) eyes were compared with infants more than 28 weeks of gestation using a multivariable dimension reduction analysis (principal component analysis) and a bilinear factor mode analysis (partial least square discriminant analysis) to determine group intervariability. Further analyses were performed to investigate the effects of gestation on foveal development. Results: Twenty-six infants born at gestational ages ranging from 22 to 39 weeks were imaged between 32 and 80 weeks postmenstrual age. A principal component analysis and partial least squares discriminant analysis revealed that the foveal inner retina thickness was the main difference between EPT infants and non-EPT infants. This difference was reflected by comparing their inner retinal thickness over time (32-80 weeks postmenstrual age), which revealed a sustained thicker foveal inner retina for EPT infants when compared with non-EPT infants. The foveal pit seemed to be shallower in EPT infants when compared with non-EPT infants. Conclusions: Twenty-eight weeks of gestation seems to be a critical timepoint for foveal development; EPT infants had altered foveal inner retinal development throughout early postnatal development, which led to a thicker foveal inner retina and a shallower foveal pit soon after birth. Translational Relevance: Measuring untreated foveal parameters informs about the effects of prematurity on the fovea and provides a baseline when comparing with post-treatment foveal development.

Insights into the developing fovea revealed by imaging.

Early development of the fovea has been documented by histological studies over the past few decades. However, structural distortion due to sample processing and the paucity of high-quality post-mortem tissue has limited the effectiveness of this approach. With the continuous progress in high-resolution non-invasive imaging technology, most notably optical coherence tomography (OCT) and OCT angiography (OCT-A), in vivo visualization of the developing retina has become possible. Combining the information from histologic studies with this novel imaging information has provided a more complete and accurate picture of retinal development, and in particular the developing fovea. Advances in neonatal care have increased the survival rate of extremely premature infants. However, with enhanced survival there has been an attendant increase in retinal developmental complications. Several key abnormalities, including a thickening of the inner retina at the foveal center, a shallower foveal pit, a smaller foveal avascular zone, and delayed development of the photoreceptors have been described in preterm infants when compared to full-term infants. Notably these abnormalities, which are consistent with a partial arrest of foveal development, appear to persist into later childhood and adulthood in these eyes of individuals born prematurely. Understanding normal foveal development is vital to interpreting these pathologic findings associated with prematurity. In this review, we first discuss the various advanced imaging technologies that have been adapted for imaging the infant eye. We then review the key events and steps in the development of the normal structure of the fovea and contrast structural features in normal and preterm retina from infancy to childhood. Finally, we discuss the development of the perifoveal retinal microvasculature and highlight future opportunities to expand our understanding of the developing fovea.

Peripheral retinal neovascularization in a patient with obstructive sleep apnea.

Purpose: To describe a case of peripheral retinal neovascularization and its possible etiological connection to comorbid obstructive sleep apnea. Observations: In this case report we describe a diabetic patient with obstructive sleep apnea who presented with bilateral peripheral retinal neovascularization but in the absence of any other evidence of diabetic retinopathy. Aside from confirmed nocturnal hypoxia and reasonably controlled diabetes mellitus, etiological investigation was otherwise unrevealing. Conclusions and Importance: In the absence of typical findings for diabetic retinopathy, nocturnal hypoxia due to obstructive sleep apnea may be a contributing factor in the development of peripheral retinal neovascularization. There may be a role for more vigilant OSA screening in patients with peripheral retinal neovascularization as treatment with positive airway pressure devices may reduce the retinal hypoxic burden.

Association Between Social Determinants of Health and Retinopathy of Prematurity Outcomes.

Importance: Previous studies suggest that race or ethnicity may be associated with risk for developing retinopathy of prematurity (ROP). Little is known about how socioeconomic factors mediate the relationship between race or ethnicity and ROP outcomes. Objective: To evaluate how socioeconomic factors, in the context of race and ethnicity, are associated with ROP outcomes. Design, Setting, and Participants: This retrospective cohort study used US Census Bureau income data and electronic medical records from neonatal intensive care units at 4 hospitals, UCLA Mattel Children's Hospital, UCLA Santa Monica Hospital, Cedars-Sinai Medical Center, and Harbor-UCLA Medical Center. Eligible participants included neonates born at a gestational age (GA) of 30 weeks or less, birth weight less than 1500 g, or a GA at birth greater than 30 weeks but with an unstable clinical course. Participants were screened for ROP between January 1, 2010, and December 31, 2020. Exposures: Race and ethnicity data, GA, demographic and clinical information, proxy household income, and health insurance status were collected as risk factors. Main Outcomes and Measures: Diagnosis and severity of ROP were the main study outcomes. Severity was determined according to a classification system developed by the Early Treatment for Retinopathy of Prematurity Cooperative Group. Results: In a crude model, Hispanic neonates were more likely to be diagnosed with ROP (OR, 1.70; 95% CI, 1.20-2.42) and had more severe ROP (OR, 2.24; 95% CI, 1.21-4.15) compared with non-Hispanic White neonates; these associations were no longer found when adjusting for GA and socioeconomic factors (OR, 1.12; 95% CI, 0.68-1.82, and OR, 1.67; 95% CI, 0.80-3.52, for ROP diagnosis and severity, respectively). In a fully adjusted model, lower GA was the primary predictor of ROP incidence (OR, 0.52; 95% CI, 0.48-0.57; P < .001), and higher median household income was associated with higher GA (OR, 0.26; 95% CI, 0.09-0.43; P = .002). Conclusions and Relevance: In this cohort study, GA was the primary driver of disparities in ROP outcomes in a heterogeneous population of neonates in Los Angeles, California. When examined in the context of socioeconomic factors, GA did not differ between racial and ethnic groups. Studies of disparities associated with race and ethnicity should consider these constructs in conjunction with other sociodemographic factors and social determinants of health.

Ocular findings associated with FADD deficiency resemble familial exudative vitreoretinopathy.

PURPOSE: We report the first known case of eye findings associated with a Fas-associated protein with death domain (FADD) gene mutation, an exceedingly rare entity. OBSERVATIONS: A 7-year-old boy was referred for decreased vision and eye examination revealed cystoid macular edema and peripheral retinal ischemia in both eyes and progression to tractional retinal detachment in the right eye. CONCLUSIONS AND IMPORTANCE: This case suggests that baseline and annual ophthalmic screening may be beneficial in individuals with FADD mutations. However, greater documentation of cases may be necessary before deriving a clear interval screening recommendation.

An unusual presentation of peripapillary pachychoroid syndrome.

PURPOSE: Peripapillary pachychoroid syndrome (PPS) is a recently described entity of the pachychoroid disease spectrum and is characterized by thickening of the nasal choroid and peripapillary fluid pockets. This case illustrates the remarkable natural history of this recently described disorder. OBSERVATION: This case report describes a patient with PPS who presented with severe cystoid macular edema (CME) that spontaneously resolved without treatment. CONCLUSIONS AND IMPORTANCE: This report indicates that PPS can exhibit significant fluctuation of CME and a favorable natural history in some cases. It also suggests that observation may be a viable option in the initial management of this finding if vision is not significantly unaffected.
