ABSTRACT

PURPOSE: To examine the effects of glucagon-like peptide-1 receptor (GLP-1) agonists compared to SGLT-2 inhibitors on diabetic retinopathy. DESIGN: Retrospective clinical cohort study using TriNetX, a federated electronic health records network comprising multiple healthcare organizations. METHODS: Patients with an International Classification of Diseases, Tenth Revision (ICD-10) code of nonproliferative diabetic retinopathy (PDR) and monotherapy treatment, excluding insulin, with GLP-1 agonists or SGLT-2 inhibitors. Patients with a history of PDR prior to initiation of treatment were excluded. The rate of progression to PDR and rate of development of diabetic macular edema (DME) were compared between patients on GLP-1 agonists compared to those on SGLT-2 inhibitors. The groups were propensity score matched for age, gender, ethnicity, race, type of diabetes, and severity of PDR. Main outcomes included rate and relative risk (RR) of progression to PDR and risk of DME in the GLP-1 agonist group versus the SGLT-2 inhibitor group. RESULTS: A total of 6481 patients were identified in the GLP-1 cohort and the SGLT-2 inhibitor cohort after propensity score matching. At 1 and 3 years after initiation of therapy, a higher rate of progression of PDR was noted (RR: 1.26, CI 1.04-1.51, P = .017 at 1 year, RR: 1.284, CI 1.1-1.499, P = .002 at 3 years) in the GLP-1 agonist cohort compared to the SGLT-2 inhibitor cohort. There was a higher rate of DME noted at 3 months (RR: 1.192, CI 1.059-1.276, P = .002), 6 months (RR: 1.22, CI 1.13-1.32, P < .001), 1 year (RR: 1.24, CI 1.15-1.33, P < .001), and at 3 years (RR: 1.29, CI 1.21-1.38, P < .001) in the GLP-1 agonist cohort compared to the SGLT-2 inhibitor cohort. CONCLUSIONS: A higher rate of progression of PDR and risk of new-onset DME was observed in patients on monotherapy with GLP-1 agonists compared to those on SGLT-2 inhibitors. It is important for clinicians to be aware of these potential effects and to consider the current retinopathy status when initiating treatment with newer hypoglycemic agents to ensure these patients are appropriately monitored for developing potential vision-threatening complications.

ABSTRACT

Objective: In a world where digital media is deeply engrained into our everyday lives, there lies an opportunity to leverage interactions with technology for health and wellness. The Vision Performance Index (VPI) leverages natural human-technology interaction to evaluate visual function using visual, cognitive, and motor psychometric data over 5 domains: field of view, accuracy, multitracking, endurance, and detection. The purpose of this study was to describe a novel method of evaluating holistic visual function through video game-derived VPI score data in patients with specific ocular pathology. Design: Prospective comparative analysis. Participants: Patients with dry eye, glaucoma, cataract, diabetic retinopathy (DR), age-related macular degeneration, and healthy individuals. Methods: The Vizzario Inc software development kit was integrated into 2 video game applications, Balloon Pop and Picture Perfect, which allowed for generation of VPI scores. Study participants were instructed to play rounds of each video game, from which a VPI score was compiled. Main Outcome Measures: The primary outcome was VPI overall score in each comparison group. Vision Performance Index component, subcomponent scores, and psychophysical inputs were also compared. Results: Vision Performance Index scores were generated from 93 patients with macular degeneration (n = 10), cataract (n = 10), DR (n = 15), dry eye (n = 15), glaucoma (n = 16), and no ocular disease (n = 27). The VPI overall score was not significantly different across comparison groups. The VPI subcomponent "reaction accuracy" score was significantly greater in DR patients (106 ± 13.2) versus controls (96.9 ± 11.5), P = 0.0220. The VPI subcomponent "color detection" score was significantly lower in patients with DR (96.8 ± 2.5; p=0.0217) and glaucoma (98.5 ± 6.3; P = 0.0093) compared with controls (101 ± 11). Psychophysical measures were statistically significantly different from controls: proportion correct (lower in DR, age-related macular degeneration), contrast errors (higher in cataract, DR), and saturation errors (higher in dry eye). Conclusions: Vision Performance Index scores can be generated from interactions of an ocular disease population with video games. The VPI may offer utility in monitoring select ocular diseases through evaluation of subcomponent and psychophysical input scores; however, future larger-scale studies must evaluate the validity of this tool.

ABSTRACT

PURPOSE: To examine rates of stroke, myocardial infarction (MI), deep vein thrombosis (DVT), pulmonary embolism (PE), and death in patients after retinal vein occlusion (RVO) compared to controls. DESIGN: Retrospective cohort study. METHODS: An aggregated electronic health records research network, TriNetX, was used to identify patients with diagnosis of RVO and a control group of patients with cataract. Patients were excluded if they had history of stroke, MI, DVT, or PE within 2 years of diagnosis of RVO or cataract. Propensity score matching was performed to control for baseline demographics and medical comorbidities. Main outcomes included relative risk (RR) of death, stroke, MI, DVT, and PE after RVO compared to those in matched controls. RESULTS: A total of 45,304 patients were included in each cohort. There was elevated risk of death in the RVO cohort compared to the control cohort at 1 year (RR = 1.30, P < .01), 5 years (RR = 1.22, P < .01), and 10 years (RR = 1.08, P < .01). There was elevated risk of stroke at 1 year (RR = 1.61, P < .01), 5 years (RR = 1.31, P < .01), and 10 years (RR = 1.18, P < .01). There was elevated risk of MI at 1 year (RR = 1.26, P < .01) and 5 years (RR = 1.13, P < .01), but not at 10 years (RR = 1.06, P = .12). There was mildly elevated risk of DVT at 1 year (RR = 1.65, P < .01) but not at 5 years (RR = 0.94, P = .94) or 10 years (RR = 1.05, P = .37). There was no elevated risk of PE at 1 year (RR = 0.98, P = 0.80), 5 years (RR = 0.95, P = .42), or 10 years (RR = 0.85, P =.40). CONCLUSIONS: There is an increased rate of death, stroke, and MI after RVO compared to those in matched controls. We emphasize the need for long-term systemic evaluation after RVO.

ABSTRACT

Purpose: Visual prognosis and treatment burden for macular neovascularization (MNV) can differ between myopic macular degeneration (MMD) and age-related macular degeneration (AMD). We describe and compare MNV associated with MMD and AMD using swept-source (SS)-OCTA. Patients and Methods: Adult patients with documented MNV associated with MMD or AMD were consecutively recruited. Qualitative and quantitative features were assessed from 6x6mm angiograms, including the MNV area and vessel density (VD). Descriptive statistics and linear regression analyses were carried out. Results: Out of 75 enrolled eyes with diagnosed MNV (30 MMD-MNV and 45 AMD-MNV; mean age 55±19 and 75±8 years, respectively), 44 eyes had discernible MNV (11 MMD-MNV and 33 AMD-MNV) on SS-OCTA at the time of the study and were included in the analysis. The MMD-MNV group exhibited a three-fold smaller sized MNV (p=0.001), lower greatest linear dimension (p=0.009) and greatest vascular caliber (p<0.001) compared to AMD-MNVs, and had a higher prevalence of tree-in-bud pattern. Eyes with AMD showed a higher prevalence of type 1 MNVs with medusa pattern. There was no difference in the location of the MNV, shape's regularity, margins, presence of core vessel, capillary fringe, peripheral loops, or perilesional dark halo (p>0.05) between both conditions. After adjustment, decreased MNV area and increased VD were associated with the tree-in-bud pattern, whereas the diagnosis did not significantly influence those parameters. Conclusion: While larger studies are warranted, this study is the first to describe and compare MMD-MNV and AMD-MNV using SS-OCTA, providing relevant clinical insight on MNV secondary to MMD and AMD. These findings also further validate OCTA as a powerful tool to detect and characterize MNV non-invasively.

ABSTRACT

Importance: Regular screening for diabetic retinopathy often is crucial for the health of patients with diabetes. However, many factors may be barriers to regular screening and associated with disparities in screening rates. Objective: To evaluate the associations between visiting an eye care practitioner for diabetic retinopathy screening and factors related to overall health and social determinants of health, including socioeconomic status and health care access and utilization. Design, Setting, and Participants: This retrospective cross-sectional study included adults aged 18 years or older with type 2 diabetes who answered survey questions in the All of Us Research Program, a national multicenter cohort of patients contributing electronic health records and survey data, who were enrolled from May 1, 2018, to July 1, 2022. Exposures: The associations between visiting an eye care practitioner and (1) demographic and socioeconomic factors and (2) responses to the Health Care Access and Utilization, Social Determinants of Health, and Overall Health surveys were investigated using univariable and multivariable logistic regressions. Main Outcome and Measures: The primary outcome was whether patients self-reported visiting an eye care practitioner in the past 12 months. The associations between visiting an eye care practitioner and demographic and socioeconomic factors and responses to the Health Care Access and Utilization, Social Determinants of Health, and Overall Health surveys in All of Us were investigated using univariable and multivariable logistic regression. Results: Of the 11 551 included participants (54.55% cisgender women; mean [SD] age, 64.71 [11.82] years), 7983 (69.11%) self-reported visiting an eye care practitioner in the past year. Individuals who thought practitioner concordance was somewhat or very important were less likely to have seen an eye care practitioner (somewhat important: adjusted odds ratio [AOR], 0.83 [95% CI, 0.74-0.93]; very important: AOR, 0.85 [95% CI, 0.76-0.95]). Compared with financially stable participants, individuals with food or housing insecurity were less likely to visit an eye care practitioner (food insecurity: AOR, 0.75 [95% CI, 0.61-0.91]; housing insecurity: AOR, 0.86 [95% CI, 0.75-0.98]). Individuals who reported fair mental health were less likely to visit an eye care practitioner than were those who reported good mental health (AOR, 0.84; 95% CI, 0.74-0.96). Conclusions and Relevance: This study found that food insecurity, housing insecurity, mental health concerns, and the perceived importance of practitioner concordance were associated with a lower likelihood of receiving eye care. Such findings highlight the self-reported barriers to seeking care and the importance of taking steps to promote health equity.

ABSTRACT

Importance: Patients with retinal artery occlusions (RAOs) are recommended to have emergent stroke workup, although the true risk of death and subsequent vascular events post-RAO is not clear. Objective: To determine short-term and long-term rates of stroke, myocardial infarction (MI), and death in patients after RAO compared with a control cohort. Design, Setting, and Participants: This retrospective cohort study used aggregated electronic health records from January 1, 2003, through April 14, 2023, from TriNetX, a network with data from more than 111 million patients. Patients with RAO and a cataract control group were identified and matched for age, sex, race, and comorbidities, including hypertension, diabetes, hyperlipidemia, and smoking status. Patients were excluded if they had a stroke or MI within 2 years before the diagnosis of RAO or cataract. Exposure: International Statistical Classification of Diseases and Related Health Problems, Tenth Revision, diagnosis code for RAO or age-related cataract. Main Outcomes and Measures: Rate of death, stroke, and MI at 2 weeks, 30 days, 1 year, 5 years, and 10 years after RAO compared with matched controls. Results: There were a total of 34 874 patients with at least 1 year of follow-up in the RAO cohort. The mean (SD) age at the RAO event was 66 (15.2) years. The rate of death after RAO diagnosis was higher than after cataract diagnosis at 2 weeks (0.14% vs 0.06%; relative risk [RR], 2.45; 95% CI, 1.46-4.12; risk difference [RD], 0.08%; 95% CI, 0.04%-0.13%; P < .001), 30 days (0.29% vs 0.14%; RR, 2.10; 95% CI, 1.49-2.97; RD, 0.15%; 95% CI, 0.08%-0.22%; P < .001), 1 year (3.51% vs 1.99%; RR, 1.78; 95% CI, 1.61-1.94; RD, 1.41%; 95% CI, 1.17%-1.66%; P < .001), 5 years (22.74% vs 17.82%; RR, 1.28; 95% CI, 1.23-1.33; RD, 4.93%; 95% CI, 4.17%-5.68%; P < .001), and 10 years (57.86% vs 55.38%; RR, 1.05; 95% CI, 1.02-1.07; RD, 2.47%; 95% CI, 1.25%-3.69%; P < .001). Risk of stroke after RAO was higher at 2 weeks (1.72% vs 0.08%; RR, 21.43; 95% CI, 14.67-31.29; RD, 1.64%; 95% CI, 1.50%-1.78%; P < .001), 30 days (2.48% vs 0.18%; RR, 14.18; 95% CI, 10.94-18.48; RD, 2.31%; 95% CI, 2.14%-2.47%; P < .001), 1 year (5.89% vs 1.13%; RR, 5.20; 95% CI, 4.67-5.79; RD, 4.64%; 95% CI, 4.37%-4.91%; P < .001), 5 years (10.85% vs 4.86%; RR, 2.24; 95% CI, 2.09-2.40; RD, 6.00%; 95% CI, 5.50%-6.50%; P < .001), and 10 years (14.59% vs 9.18%; RR, 1.59; 95% CI, 1.48-1.70; RD, 5.41%; 95% CI, 4.62%-6.21%; P < .001). Risk of MI after RAO was higher at 2 weeks (0.16% vs 0.06%; RR, 3.00; 95% CI, 1.79-5.04; RD, 0.11%; 95% CI, 0.06%-0.16%; P < .001), 30 days (0.27% vs 0.10%; RR, 2.61; 95% CI, 1.78-3.83; RD, 0.17%; 95% CI, 0.10%-0.23%; P < .001), 1 year (1.66% vs 0.97%; RR, 1.72; 95% CI, 1.51-1.97; RD, 0.59%; 95% CI, 0.42%-0.76%; P < .001), 5 years (6.06% vs 5.00%; RR, 1.21; 95% CI, 1.12-1.31; RD, 1.07%; 95% CI, 0.64%-1.50%; P < .001), and 10 years (10.55% vs 9.43%; RR, 1.12; 95% CI, 1.04-1.21; RD, 1.13%; 95% CI, 0.39%-1.87%; P = .003). Conclusions and Relevance: This study showed an increased risk of death, stroke, and MI in patients with RAO at both short-term and long-term intervals after RAO compared with a matched control population diagnosed with cataract. These findings suggest a potential need for multidisciplinary evaluation and long-term systemic follow-up of patients post-RAO.

ABSTRACT

Importance: Large language models (LLMs) like ChatGPT appear capable of performing a variety of tasks, including answering patient eye care questions, but have not yet been evaluated in direct comparison with ophthalmologists. It remains unclear whether LLM-generated advice is accurate, appropriate, and safe for eye patients. Objective: To evaluate the quality of ophthalmology advice generated by an LLM chatbot in comparison with ophthalmologist-written advice. Design, Setting, and Participants: This cross-sectional study used deidentified data from an online medical forum, in which patient questions received responses written by American Academy of Ophthalmology (AAO)-affiliated ophthalmologists. A masked panel of 8 board-certified ophthalmologists were asked to distinguish between answers generated by the ChatGPT chatbot and human answers. Posts were dated between 2007 and 2016; data were accessed January 2023 and analysis was performed between March and May 2023. Main Outcomes and Measures: Identification of chatbot and human answers on a 4-point scale (likely or definitely artificial intelligence [AI] vs likely or definitely human) and evaluation of responses for presence of incorrect information, alignment with perceived consensus in the medical community, likelihood to cause harm, and extent of harm. Results: A total of 200 pairs of user questions and answers by AAO-affiliated ophthalmologists were evaluated. The mean (SD) accuracy for distinguishing between AI and human responses was 61.3% (9.7%). Of 800 evaluations of chatbot-written answers, 168 answers (21.0%) were marked as human-written, while 517 of 800 human-written answers (64.6%) were marked as AI-written. Compared with human answers, chatbot answers were more frequently rated as probably or definitely written by AI (prevalence ratio [PR], 1.72; 95% CI, 1.52-1.93). The likelihood of chatbot answers containing incorrect or inappropriate material was comparable with human answers (PR, 0.92; 95% CI, 0.77-1.10), and did not differ from human answers in terms of likelihood of harm (PR, 0.84; 95% CI, 0.67-1.07) nor extent of harm (PR, 0.99; 95% CI, 0.80-1.22). Conclusions and Relevance: In this cross-sectional study of human-written and AI-generated responses to 200 eye care questions from an online advice forum, a chatbot appeared capable of responding to long user-written eye health posts and largely generated appropriate responses that did not differ significantly from ophthalmologist-written responses in terms of incorrect information, likelihood of harm, extent of harm, or deviation from ophthalmologist community standards. Additional research is needed to assess patient attitudes toward LLM-augmented ophthalmologists vs fully autonomous AI content generation, to evaluate clarity and acceptability of LLM-generated answers from the patient perspective, to test the performance of LLMs in a greater variety of clinical contexts, and to determine an optimal manner of utilizing LLMs that is ethical and minimizes harm.

ABSTRACT

Myopia is a known risk factor for rhegmatogenous retinal detachment (RRD). Given global trends of increasing myopia, we aimed to determine the absolute risk (incidence rate) of RRD in non-myopes, myopes and high myopes in the United States over ten years. We performed a retrospective cohort study of 85,476,781 commercially insured patients enrolled in the Merative™ Marketscan® Research Database. The incidence rate of RRD in phakic patients in the United States was 39-fold higher in high myopes than non-myopes (868.83 per 100,000 person-years versus 22.44 per 100,000 person-years) and three-fold higher in myopes than non-myopes (67.51 per 100,000 person-years versus 22.44 per 100,000 person-years). The incidence rate was significantly higher in males in each category (P < 0.01). Combined, the incidence rate of RRD in phakic patients in the United States from 2007 to 2016 was 25.27 RRDs per 100,000 person-years, a rate higher than those in prior published studies in North America, South America, Europe, Asia, and Australia. The absolute risk of myopia and high myopia increased from 2007 to 2016. The risk of RRD in phakic high myopes rose with increasing age. Notably, the magnitude of increased risk of RRD in myopes varied substantially according to the minimum follow-up period in our models and should be accounted for when interpreting data analyses.

ABSTRACT

BACKGROUND/AIMS: Pathological myopia (PM) is a leading cause of blindness worldwide. We aimed to evaluate microvascular and chorioretinal changes in different stages of myopia with wide-field (WF) swept-source (SS) optical coherence tomography angiography (OCTA). METHODS: This prospective cross-sectional observational study included 186 eyes of 122 patients who had undergone imaging between November 2018 and October 2020. Vessel density (VD) and vessel skeletonised density (VSD) of superficial capillary plexus, deep capillary plexus and whole retina, as well as foveal avascular zone parameters, retinal thickness (RT) and choroidal thickness (CT), were calculated. RESULTS: This study evaluated 75 eyes of 48 patients with high myopia (HM), 43 eyes of 31 patients with mild to moderate myopia and 68 eyes of 53 age-matched controls. Controlling for age and the presence of systemic hypertension, we found that HM was associated with decrease in VD and VSD in all layers on 12×12 mm² scans. Furthermore, HM was associated with a VD and VSD decrease in every Early Treatment Diabetic Retinopathy Study grid, with a larger decrease temporally (ßVD=-0.39, ßVSD=-10.25, p<0.01). HM was associated with decreased RT and CT. Reduction in RT was outside the macular region, while reduction in CT was in the macular region. CONCLUSION: Using WF SS-OCTA, we identified reduction in microvasculature and structural changes associated with myopia. Decrease in VD and VSD was greater in the temporal quadrant, and reductions in RT and CT were uneven across the retina. Further work may help identify risk factors for the progression of PM and associated vision-threatening complications.

ABSTRACT

OBJECTIVE: Vision changes can precipitate falls in the elderly resulting in significant morbidity and mortality. We hypothesized that pseudophakic monovision and ensuing anisometropia and aniseikonia impact elderly fall risk. This study assessed fall risk in patients with pseudophakic monovision, pseudophakic single vision distance (classic cataract surgery), and cataracts with no surgery. DESIGN: Retrospective single-institution cohort study PARTICIPANTS: Patients with bilateral cataracts diagnosed at 60 years of age or older who underwent bilateral cataract surgery (monovision or single vision distance) or did not undergo any cataract surgery (n = 13 385). Patients with unilateral surgery or a fall prior to cataract diagnosis were excluded. METHODS: Data were obtained from the Stanford Research Repository. Time-to-fall analysis was performed across all 3 groups. Primary outcome was hazard ratio (HR) for fall after second eye cataract surgery or after bilateral cataract diagnosis. RESULTS: Of 13 385 patients (241 pseudophakic monovision, 2809 pseudophakic single vision, 10 335 no surgery), 850 fell after cataract diagnosis. Pseudophakic monovision was not associated with fall risk after controlling for age, sex, and myopia. Pseudophakic single-vision patients had a decreased time to fall compared with no-surgery patients (log rank, p < 0.001). Older age at cataract diagnosis (HR =1.05, 95% confidence interval [CI] 1.04-1.06, p < 0.001) or at time of surgery (HR = 1.05, 95% CI 1.03-1.07, p < 0.001) increased fall risk, as did female sex (HR = 1.29, 95% CI 1.10-1.51, p = 0.002) and preexisting myopia (HR = 1.31, 95% CI 1.01-1.71, p = 0.046) among nonsurgical patients. CONCLUSIONS: Pseudophakic monovision did not impact fall risk, but pseudophakic single vision may increase falls compared with patients without cataract surgery.

ABSTRACT

Purpose: To report different biometric measurements in high myopia associated with different underlying ocular and genetic conditions. Design: Retrospective study. Subjects: Patients with high myopia. Methods: We searched the Stanford Research Repository tool to identify patients with the diagnosis of high myopia who were seen by a single provider at Byers Eye Institute at Stanford from January 2019 to March 2022. We performed a chart review and included eyes that had high myopia and ocular biometric measurements at any time point after January 2019. We divided our cohort into 5 different groups: (1) isolated high myopia (IHM) (control group); (2) retinopathy of prematurity (ROP); (3) familial exudative vitreoretinopathy; (4) Marfan syndrome; and (5) Stickler syndrome. Main Outcome Measures: Biometric measurements. Results: A total of 246 patients (432 eyes) were included as follows: 202 patients (359 eyes) in the IHM group, 17 patients (27 eyes) in the ROP group, 7 patients (12 eyes) in the familial exudative vitreoretinopathy group, 8 patients (14 eyes) in the Marfan group, and 12 patients (20 eyes) in the Stickler group. The ROP group showed significantly shorter axial lengths, shallower anterior chambers, and thicker lenses compared with the IHM group. The Marfan group showed significantly flatter corneas and thicker lenses compared with the IHM group. The Stickler group showed significantly longer axial lengths compared with the IHM group. Conclusions: High myopia is associated with variable biometric measurements according to underlying ocular or genetic conditions. Retinopathy of prematurity-associated high myopia is primarily lenticular, while Stickler syndrome-associated high myopia is axial. Marfan syndrome-associated high myopia is derived from both axial and lenticular mechanisms.

ABSTRACT

Purpose: The guarded light pipe is a recently described alternative endoillumination technique to chandelier illumination. We sought to compare the outcomes of scleral buckling (SB) under indirect ophthalmoscopy (ID) to heads-up three-dimensional visualization with a guarded light pipe (3DGLP). Methods: A retrospective comparative study was performed, including 47 eyes that underwent SB for rhegmatogenous retinal detachment (RRD) repair with either traditional ID (n = 31) or 3DGLP (n = 16). Results: The single surgery anatomic success rate was 87.0% in the ID group and 87.5% in the 3DGLP group. The final anatomic success rate was 100% in both groups. The median (interquartile range) post-operative logMAR was 0.10 (0.0-0.20) in the ID group and 0.08 (0.02-0.69) in the 3DGLP group (p = 0.51). The median operative time was 107 (94-123) minutes in the ID group and 100 (90-111) minutes in the 3DGLP group (p = 0.25). Among eyes that underwent subretinal fluid drainage, the operative time was significantly longer in the ID group compared to the 3DGLP group, 113 (100-135) minutes vs 93 (85-111) minutes (p = 0.035). There were no post-operative complications in the ID group and one complication of self-resolving vitreous hemorrhage associated with a malfunctioning cryoprobe in the 3DGLP group (p = 0.34). There were no cases of post-operative cataract progression in either group. Conclusion: Compared to traditional SB, 3DGLP improves ergonomics and educational value with similar anatomical, visual, intra and post-operative outcomes and may result in shorter operative time in cases requiring subretinal fluid drainage.

ABSTRACT

Purpose: This work evaluates trends in achievement of women in the retina field, through an analysis of gender representation in the American Society of Retina Specialists (ASRS). Methods: This retrospective, longitudinal study spans 1983 to 2020. Historical data classified by male or female gender were collected from ASRS's overall membership, board of directors and officers, and recipients of the 4 society awards. The proportion of each benchmark held by women was compared with prior decades since the founding of ASRS using the Fisher's exact test. Results: Women's representation increased from 11% of ASRS members in 2007 to 19.7% in 2020. From 2010 to 2019, women received a higher proportion of society awards (21.1%) compared with membership prior to the start of that decade. In 2020, women were proportionally well represented in board of director positions (21.9%) and held a significantly higher proportion of board positions than in the period 1983 to 1989 (P = .02). From 1983 to 2020, women held 4.3% (1 of 23) of presidencies. Conclusions: Although the number of women in retina is increasing, women remain underrepresented in the leadership of ASRS. Interventions to increase exposure to female mentorship and improve childcare benefits are warranted to engage female ophthalmology trainees in retina and ultimately society leadership.

ABSTRACT

BACKGROUND/AIMS: To determine whether timing of ophthalmic screening influences prevalence of neonatal fundus haemorrhages. We compared the prevalence of fundus haemorrhages in two populations: term newborns screened early (less than 72 hours) and preterm newborns screened late (4-11 weeks). Additionally, we reviewed the literature on timing and prevalence of newborn haemorrhages. METHODS: Retrospective observational cohort study. Infants who underwent wide-angle ophthalmic digital imaging over one overlapping year in the Newborn Eye Screen Testing (NEST) or Stanford University Network for Diagnosis of Retinopathy of Prematurity (SUNDROP) programme were included. The PubMed database was filtered to include English-language articles dating back to 1950. Nine articles were selected for review based on inclusion of the prevalence of newborn fundus haemorrhages at multiple time points. RESULTS: A total of 202 patients received early imaging in the NEST cohort and 73 patients received late imaging in the SUNDROP cohort. In the NEST cohort, 20.2% of newborns had haemorrhages. In contrast, we found haemorrhages in only one case or 1.4% of the SUNDROP cohort. Using prevalence data from nine additional studies, we developed a predicted probabilities model of newborn haemorrhages. Per this model, the probability of seeing a haemorrhage if you screen an infant at 1 hour is 18.8%, at 2 weeks is 2.9% and at 1 month is 0.28%. CONCLUSION: We found a significant difference in the prevalence of fundus haemorrhages between the early-screened NEST cohort and the late-screened, preterm SUNDROP cohort. Likely, this difference is due to the transient nature of most newborn haemorrhages.

ABSTRACT

PURPOSE: Whether intravitreal anti-vascular endothelial growth factors (VEGFs) cause retinal atrophy is still a subject of debate. We reported 13 eyes that received several injections of anti-VEGF for wet age-related macular degeneration (AMD) with good visual acuity despite geographic atrophy on imaging. METHODS: This is a case series study conducted at Byers Eye Institute at Stanford University. Patients of three retina specialists with wet AMD who received six or more intravitreal injection of anti-VEGFs with visual acuity of 20/60 or better and incomplete RPE and outer retina atrophy (iRORA) or complete RPE and outer retinal atrophy (cRORA) were enrolled in this case series. Different imaging modalities were reviewed by three retina specialists comparing the baseline with the most recent exam. RESULTS: About 13 eyes of 10 patients met the selection criteria. Eleven eyes were classified as iRORA and 2 as cRORA. Despite the development of macular atrophy on imaging after an average of 38.1 injections, eyes maintained stable visual acuity. CONCLUSION: The discrepancy between structural and functional findings in this cohort suggests that patients treated by anti-VEGF drugs exhibit divergent clinical outcomes for currently unknown reasons. The authors propose anti-VEGF may affect melanosomes within RPE without disrupting RPE and photoreceptors function completely. This requires further investigation.

ABSTRACT

PURPOSE: We report an unusual case of likely combined retinal artery occlusion and retinal vein occlusion following a sneeze. Widefield swept source optical coherence tomography-angiography (WF-SS-OCTA) was used to analyze retinal changes at one-month follow-up. METHODS: The patient reported visual symptoms in his left eye immediately after sneezing five times in a row. Fundus examination showed an embolus along the superior arcade. Stroke workup revealed moderate carotid artery stenosis and a subtherapeutic INR. At one-month follow-up, fundus photography and SS-OCTA were obtained. RESULTS: Fundus photography showed superior retinal whitening and arteriole attenuation, an inferior perifoveal cotton wool spot, and inferotemporal intraretinal hemorrhages. SS-OCTA showed loss of the deep capillary plexus superiorly and inferotemporally, most consistent with combined retinal artery and retinal vein occlusion. CONCLUSION: We report the first case of sneeze-induced combined retinal artery and retinal vein occlusion. The retina is a uniquely accessible window that provides insight into human physiology, and SS-OCTA is a powerful tool that can give further insight into the pathophysiology of an occlusion.

ABSTRACT

Universal newborn eye screening can identify ocular abnormalities early and help mitigate long-term visual impairment. Traditional neonatal and infant eye screening is administered by neonatologists and pediatricians using the red reflex test. If this test identifies an ocular abnormality, then the patient is examined by an ophthalmologist. Notably, the red reflex test may be unable to detect amblyogenic posterior segment pathology. Recent studies using fundus imaging and telemedicine show reduced cost of human resources and increased sensitivity compared with traditional approaches. In this review, the authors discuss universal newborn eye screening pilot programs with regard to disease prevalence, referral-warranted disease, and cost-effectiveness.
