RESUMEN
PURPOSE: Conversion to neovascular disease in patients with non-neovascular age-related macular degeneration (AMD) initiated on direct oral anticoagulants (DOAC) compared to matched patients treated with warfarin. DESIGN: Retrospective cohort study. SUBJECTS, PARTICIPANTS, AND/OR CONTROLS: The study included 20,300 patients and 13,387 patients with non-neovascular AMD initiated on DOACs or warfarin, respectively, before propensity score matching (PSM). METHODS, INTERVENTION, OR TESTING: TriNetX (Cambridge, MA, USA), was used to identify patients diagnosed with non-neovascular AMD stratified by treatment with DOACs or warfarin with at least six months of follow-up. Propensity score matching was performed to control for baseline demographics and medical comorbidities. MAIN OUTCOME MEASURES: Relative risk (RR) of developing neovascular AMD, macular hemorrhage (MH), vitreous hemorrhage (VH), and requiring an ocular intervention (intravitreal anti-vascular endothelial growth factor (VEGF) therapy or pars plana vitrectomy (PPV)) within six months and one year. Patients with chronic atrial fibrillation (AF) on anticoagulation were separately evaluated for the same measures within 5 years after initiating therapy. RESULTS: Treatment with warfarin was associated with higher risk of developing neovascular AMD at six months (RR,1.24, 95% CI, 1.12 - 1.39; P<.001) and one year (RR, 1.26, 95% CI, 1.14 - 1.40; P<.001) when compared to matched patients treated with DOACs. There was an increased risk of requiring intravitreal anti-VEGF therapy (6 months: RR, 1.30; 95% CI, 1.13-1.49; P<.001; 1 year: RR, 1.31, 95% CI, 0.72 - 2.05; P<.001) and PPV (6 months: RR, 1.16; 95% CI, 1.16-3.94; P = .01; 1 year: RR, 2.29, 95% CI, 1.30 - 4.05; P=.003). Among patients with AMD and AF treated with warfarin, there was an increased risk of ocular complications (neovascular AMD: RR, 1.25; 95% CI, 1.14-1.38; P<.001; MH: RR, 1.86; 95% CI, 1.47-2.35; P<.001; VH: RR, 2.22; 95% CI, 1.51-3.26; P<.001) and need for intravitreal anti-VEGF therapy (RR, 1.34; 95% CI, 1.18-1.52; P<.001) over an extended 5-year period. There was no significant difference in the development of major systemic hemorrhagic events between the two cohorts over five years. CONCLUSIONS: Patients with non-neovascular AMD treated with warfarin were more likely to develop neovascular disease and require ocular intervention for hemorrhagic complications when compared to matched patients initiated on DOACs.
RESUMEN
PURPOSE: Evaluate the risk of diabetic retinopathy progression and systemic vascular events, including death, in patients with non-proliferative diabetic retinopathy (NPDR) with obstructive sleep apnea (OSA). DESIGN: Retrospective cohort study. METHODS: Electronic chart query using TriNetX (Cambridge, MA, USA), an electronic health records network comprising data from over 124 million patients. Patients with NPDR with and without OSA were identified. Patients were excluded if they had history of proliferative disease (PDR), diabetic macular edema (DME), or prior ocular intervention (intravitreal injection, laser, or pars plana vitrectomy). Propensity score matching was performed to control for baseline demographics and comorbidities. Rate of progressing to vision threatening complications (VTCs), need for ocular intervention, and systemic events was measured at 1, 3, and 5 years. RESULTS: 11,931 patients in each group were analyzed after propensity score matching. There was elevated risk of PDR in the OSA cohort at 1 (RR: 1.34, P<0.001), 3 (RR: 1.31, P<0.001), and 5 years (RR: 1.28, P<0.001). There was elevated risk of DME in the OSA group at all time points: 1 (RR: 1.31, P<0.001), 3 (RR: 1.19, P<0.001), and 5 years (RR: 1.18, P<0.001). With respect to ocular interventions, there was an increased risk of intravitreal injection in OSA patients at 1 (RR: 1.59, P<0.001), 3 (RR: 1.58, P<0.001), and 5 years (RR: 1.54, P<0.001), and similar trends were noted with laser photocoagulation, but not vitrectomy. Regarding systemic events, NPDR patients with OSA had a greater risk of stroke (1 year RR: 1.80, P<0.001; 3 year RR: 1.56, P<0.001; 5 year RR: 1.49, P<0.001), myocardial infarction (1 year RR: 1.51, P<0.001; 3 year RR: 1.46, P<0.001; 5 year RR: 1.43, P<0.001), and death (1 year RR: 1.31, P<0.001; 3 year RR: 1.19, P<0.001; 5 year RR: 1.15, P<0.001). CONCLUSIONS: There is an increased rate of DR progression to VTCs, need for ocular intervention, and systemic complications, including death, for patients with OSA. We emphasize the need for improved screening measures of patients with NPDR and potential OSA.
RESUMEN
Mitochondria-related neurodegenerative diseases have been implicated in the disruption of primary cilia function. Mutation in an intrinsic mitochondrial complex I component NDUFAF2 has been identified in Leigh syndrome, a severe inherited mitochondriopathy. Mutations in ARMC9, which encodes a basal body protein, cause Joubert syndrome, a ciliopathy with defects in the brain, kidney, and eye. Here, we report a mechanistic link between mitochondria metabolism and primary cilia signaling. We discovered that loss of NDUFAF2 caused both mitochondrial and ciliary defects in vitro and in vivo and identified NDUFAF2 as a binding partner for ARMC9. We also found that NDUFAF2 was both necessary and sufficient for cilia formation and that exogenous expression of NDUFAF2 rescued the ciliary and mitochondrial defects observed in cells from patients with known ARMC9 deficiency. NAD+ supplementation restored mitochondrial and ciliary dysfunction in ARMC9-deficient cells and zebrafish and ameliorated the ocular motility and motor deficits of a patient with ARMC9 deficiency. The present results provide a compelling mechanistic link, supported by evidence from human studies, between primary cilia and mitochondrial signaling. Importantly, our findings have significant implications for the development of therapeutic approaches targeting ciliopathies.

Importance: The Diabetic Retinopathy Clinical Research Network Protocol S suggested that vitrectomy for vitreous hemorrhage (VH) or tractional retinal detachment (TRD) was more common among eyes assigned initially to panretinal photocoagulation (PRP) vs anti-vascular endothelial growth factor (anti-VEGF) for proliferative diabetic retinopathy (PDR). These clinical implications warrant further evaluation in the clinical practice setting. Objective: To explore outcomes of PDR treated with PRP monotherapy compared with matched patients treated with anti-VEGF monotherapy. Design, Setting, and Participants: Retrospective cohort study using an aggregated electronic health records research network. Patients with PDR who received PRP or anti-VEGF monotherapy between January and September 2023 were included before propensity score matching. Patients were excluded with 6 or fewer months' follow-up after monotherapy or with a combination of PRP and anti-VEGF. Data were analyzed in September 2023. Exposures: Patients with new PDR diagnoses stratified by monotherapy with PRP or anti-VEGF agents using Current Procedural Terminology code. Main Outcome Measures: Incidence of pars plana vitrectomy (PPV), VH, or TRD. Results: Among 6020 patients (PRP cohort: mean [SD] age, 64.8 [13.4]; 6424 [50.88%] female; 3562 [28.21%] Black, 6180 [48.95%] White, and 2716 [21.51%] unknown race; anti-VEGF cohort: mean [SD] age, 66.1 [13.2]; 5399 [50.52%] male; 2859 [26.75%] Black, 5377 [50.31%] White, and 2382 [22.29%] unknown race) who received treatment, PRP monotherapy was associated with higher rates of PPV when compared with patients treated with anti-VEGF monotherapy at 5 years (RR, 1.18; 95% CI, 1.05-1.36; RD, 1.37%; 95% CI, 0.39%-2.37%; P < .001), with similar associations at 1 and 3 years. PRP monotherapy was associated with higher rates of VH at 5 years (relative risk [RR], 1.72; 95% CI, 1.52-1.95; risk difference [RD], 7.05; 95% CI, 5.41%-8.69%; P < .001) and higher rates of TRD at 5 years (RR, 2.76; 95% CI, 2.26-3.37; RD, 4.25%; 95% CI, 3.45%-5.05%; P < .001), with similar magnitudes of associations at 6 months, 1 year, and 3 years, when compared with patients treated with anti-VEGF monotherapy. Conclusions and Relevance: These findings support the hypothesis that patients with PDR treated with PRP monotherapy are more likely to develop VH, TRD, and undergo PPV when compared with matched patients treated with anti-VEGF monotherapy. However, given the wide range in relative risk, confounding factors may account for some of the association between PRP vs anti-VEGF monotherapy and outcomes evaluated.

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.
RESUMEN
PURPOSE: To evaluate associations between ocular manifestations of Marfan syndrome and cardiovascular complications. DESIGN: Retrospective cohort study. METHODS: The TriNetX Analytics platform, a federated health research network of aggregated deidentified electronic health record data of more than 119 million patients, was used to identify patients diagnosed with Marfan syndrome. Univariate logistic regression models were used to evaluate the association of ocular manifestations of Marfan syndrome (such as retinal tears/detachment, lens dislocation, and myopia), with cardiovascular comorbidities. Additional sensitivity analyses were performed using propensity matching. Odds ratios and 95% CIs were calculated for incidence of cardiovascular comorbidities (including aortic dissection, valvular disease, and arrhythmias) following diagnosis of Marfan syndrome. RESULTS: A total of 19,105 patients were identified who were diagnosed with Marfan disease without ocular manifestations, and an additional 3887 Marfan patients with ocular comorbidities. Patients who were diagnosed with ocular disease included 883 with ectopic lens, 417 with retinal tear or detachment, 683 with aphakia, 534 with pseudophakia, and 2465 with myopia. Patients with any ocular manifestations of Marfan were significantly more likely to be diagnosed with all cardiovascular comorbidities modeled including aortic aneurysm and dissection (OR 2.035; P < .0001), mitral valve prolapse (OR 2.725; P < .0001), tricuspid valve disorders (OR 2.142; P < .0001), cardiac arrhythmias (OR 1.836; P < .0001), and all cardiovascular outcomes combined (OR 2.194; P < .0001). CONCLUSIONS: In a large and diverse cohort of patients with Marfan syndrome, ocular manifestations of the disorder appear strongly associated with cardiovascular comorbidities.

Antielevation syndrome is commonly described following anteriorization of the inferior oblique muscle. A similar phenomenon may occur following inferior oblique muscle recession, creating a distinct strabismus pattern in the setting of cranial trochlear nerve palsy. We report 3 adult patients, 69-72 years of age, who presented at the Stanford Byers Eye Institute with a similar strabismus pattern-limited elevation in abduction following previous inferior oblique muscle recession for congenital/long-standing trochlear nerve palsy. All 3 patients had a small hypertropia in primary gaze with ipsilateral inferior oblique overaction, limited elevation in abduction, and inferotemporal conjunctival scars. Two patients had a V-pattern strabismus. Following myectomy of the previously recessed inferior oblique muscle, elevation in abduction improved, and symptoms resolved in all 3 patients.

Vernal keratoconjunctivitis (VKC) is a chronic, progressive, and potentially sight-threatening form of ocular inflammatory disease that primarily affects children and young adults. Prevalence varies by region, ranging from <2 per 10,000 in the United States to as high as 1,100 per 10,000 in parts of Africa. The rarity of VKC in developed countries can make differential diagnosis challenging, and treatment is often delayed until the disease is advanced, and symptoms are significantly impacting patients' quality of life. Although once viewed primarily as an immunoglobulin E-mediated condition, approximately 50% of patients with VKC do not exhibit allergic sensitization. It is now recognized that the immunopathology of VKC involves multiple inflammatory pathways that lead to the signs, symptoms, and conjunctival eosinophilic and fibroproliferative lesions that are a hallmark of the disease. We examine the evolution of our understanding of the immunopathology of VKC, the expanding VKC treatment armamentarium, the clinical implications of emerging treatment approaches, and future directions for VKC research and practice.

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.

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 34â¯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.

Well-known risk factors for anterior segment ischemia (ASI) following strabismus surgery include ipsilateral surgery on three or more rectus muscles, older age, and vasculopathy. ASI is rarely reported in young patients following uneventful strabismus surgery on two ipsilateral rectus muscles. We report a 30-year-old transgender female on long-term estrogen therapy who underwent strabismus surgery involving recessions of both lateral rectus muscles, the right inferior rectus muscle, and the left superior rectus muscle. The left eye developed severe ASI with hypotony maculopathy that was resistant to topical medications, oral steroids, anterior chamber reformation, and intravitreal steroid injection. Following phacoemulsification with intraocular lens and capsular tension ring insertion 1 year later, intraocular pressure and hypotony maculopathy improved.

PURPOSE: To characterize the demographics, eye-related comorbidities, clinical characteristics, clinical outcomes, type of amblyopia tests used, and treatment patterns of a large cohort of pediatric, teenage, and adult amblyopic patients from the IRIS (Intelligent Research in Sight) Registry. METHODS: In this retrospective electronic health record analysis, we analyzed 456,818 patients, of whom 197,583 (43.3%) were pediatric patients; 65,308 (14.3%), teenagers; and 193,927 (42.5%), adults. Baseline best-corrected visual acuity examination in both eyes was conducted within 90 days prior to index date. Three age cohorts were analyzed based on age at the index date: pediatric (3-12 years), teen (13-17 years), and adult (18-50 years). RESULTS: At index date, unilateral amblyopia was more common than bilateral amblyopia in all age cohorts (pediatric, 55% vs 45%; teen, 61% vs 39%; adult, 63% vs 37%). In unilateral amblyopic patients, severe amblyopia was more frequent in adults (21%) than in pediatric patients (12%) and teenagers (13%); in bilateral amblyopic patients, severity was comparable in pediatric patients and adults (4% severe in both). The greatest level of visual acuity improvement was demonstrated in pediatric patients with severe unilateral amblyopia at baseline. Pediatric patients showed significant improvement in stereopsis over time at years 1 (P = 0.000033) and 2 (P = 0.000039) at the population level (per χ2 test vs baseline). CONCLUSIONS: Our findings highlight the need for more efficacious amblyopia therapies in older, more severe patients with refractory disease.

BACKGROUND AND OBJECTIVE: To investigate popular eye health supplements available on Amazon Marketplace to increase awareness about their efficacy, safety, and the validity of their purported benefits. MATERIALS AND METHODS: An observational quantitative and qualitative analysis of the top 100 eye health products was performed in March 2019. To determine the popular online eye health products on Amazon Marketplace, eight keywords were used for the search: "Eye Health," "Eye Health Supplements," "Eye Health Vitamins," "Retina Vitamins," "Macular Degeneration," "Macular Degeneration Vitamins," "Macular Health," and "Vision Health." The active ingredients, cost, and customer rating were all recorded. RESULTS: No statistically significant association was found between product type and price of the product, number of supplements, average rating, number of customer reviews, or number of verified customer reviews. The average daily cost of the eye health supplements was $0.72 ± $0.55 (range, $0.05 to $2.67). CONCLUSION: This study evaluated popular eye health supplements publicly available on Amazon Marketplace. The findings of this study help both patients and physicians better understand the safety and efficacy of these products so they may make more informed choices when supporting their eye health with commercially available supplements.

PURPOSE: To describe the characteristics and prevalence of strabismus and nystagmus in children diagnosed with cataracts using a national insurance claims database. DESIGN: Population-based retrospective cohort study. METHODS: Patients aged <13 years diagnosed with cataracts (traumatic cataracts excluded) and enrolled continuously in their health care program for ≥5 years after their first cataract diagnosis were identified in a retrospective review of 66 million charts in Optum's de-identified Clinformatics Data Mart Database between 2003 and 2015. Patients were categorized based on age of their first diagnosed cataract, and if cataract surgery was performed. Clinical and demographic factors associated with the occurrence of strabismus and nystagmus were evaluated. RESULTS: Of 1636 children diagnosed with cataract, 434 (26.5%) and 109 (6.7%) were diagnosed with strabismus and nystagmus, respectively. Both strabismus and nystagmus were more common in those who underwent cataract surgery (P < .001) and in patients diagnosed with cataract at ≤12 months of age (P < .001). Survival analysis demonstrated that strabismus and nystagmus may be diagnosed 8 years after the initial cataract diagnosis. Cox proportional hazard regression analyses revealed strabismus was associated with cataract surgery, nystagmus, and the diagnosis with cataract at ≤12 months and cataract surgery at >12 months. CONCLUSIONS: As strabismus and nystagmus occur more frequently in children diagnosed with cataracts necessitating cataract surgery, regular long-term follow-up is crucial for these children to monitor for the development of strabismus and nystagmus.

PURPOSE: To characterize delays in diagnosis and treatment of retinal detachments (RDs) in a pediatric population. DESIGN: Retrospective cohort study using insurance claims data. SUBJECTS: Pediatric patients with RD who underwent repair in the outpatient setting. METHODS: A retrospective analysis of commercially insured patients from a national cohort (IBM MarketScan Research Databases) aged ≤ 18 years with an incident diagnosis of RD between 2007 and 2016. Patients with preceding eye-related visits, time to diagnosis, and time to repair were calculated and compared between patients with pre-existing ocular diagnosis and those without. MAIN OUTCOME MEASURES: The time from diagnosis to specialist consultation, time from diagnosis to repair, time from specialist consultation to repair, number of preceding visits, and presence of previous eye-related diagnosis. RESULTS: Our sample consisted of 826 patients, the majority (77%) of whom were diagnosed with rhegmatogenous RD. Only 40% of patients had at least 1 preceding eye-related visit, and 33% had at least 2 visits before RD diagnosis, with a median time from the last eye-related visit of 32 days (4-197 days) and median time from the second to last visit of 118 days (24-437 days). The median time from RD diagnosis to repair was 2 days (0-9 days). The 323 (37.9%) patients with pre-existing ocular diagnoses more frequently had at least 1 (44% vs. 37%; P = 0.079) or 2 preceding eye-related visits (40% vs. 29%; P = 0.002) compared with those without and also had a shorter time to RD diagnosis (median, 14.5 days vs. 44.5 days; P = 0.011) and repair (1 day vs. 3 days; P = 0.003). CONCLUSIONS: Retinal detachment is an important cause of morbidity in children. This work highlighted how pediatric patients without previous ocular diagnoses and visits with eye care professional may have a delayed diagnosis and repair of their RD.

Purpose: The objective of this study was to identify the prevalence of CMV ocular disease in children and to identify associated risk factors for ocular involvement. Design: Retrospective multicenter, cross-sectional study. Methods: Setting: Hospitalized patients screened for CMV viremia by PCR between 2005 and 2018 at four pediatric referral centers. Participants: Seven-hundred and ninety-three children showed CMV viremia (>135 copies/mL by polymerase chain reaction; PCR). Main Outcomes and Measures: (1) Occurrence of ophthalmologic examination. (2) Presence of CMV ocular disease, defined as retinitis, vasculitis, hemorrhage, optic nerve atrophy, or anterior uveitis in the setting of CMV viremia without other identifiable causes. Results: A total of 296/793 (37%) underwent ophthalmologic examination following CMV viremia. A total of23/296 patients (8%) had ocular symptoms prompting evaluation while the rest had eye exams for baseline screening unrelated to CMV viremia. Of these, 13 cases (4% of those with an eye exam) with ocular disease were identified (three congenital CMV, five severe combined immunodeficiency disorder (SCID) status post-stem cell transplantation, three hematologic malignancy status post-stem cell transplantation for two of them, one Evans syndrome status post-stem cell transplantation, and one medulloblastoma status post-bone marrow transplantation). No patients with solid organ transplantation developed CMV ocular disease in our cohort. Conclusion: CMV ocular disease was a rare occurrence in this cohort without an identifiable pattern across sub-groups. Excluding the three congenital CMV cases, nine out of ten patients with CMV ocular disease were status post-stem cell transplantation. We provide integrated screening guidelines based on the best available evidence for this rare condition.
RESUMEN
BACKGROUND: Delayed treatment of congenital or infantile cataracts can cause deprivation amblyopia. Prompt diagnosis and surgical intervention is critical for optimal outcomes. This study assessed referral patterns for congenital or infantile cataracts in two regions of the United States. METHODS: The medical records of children 0-1 years of age with congenital or infantile cataracts at Stanford University (2008-2018) and Emory University (2010-2015) were reviewed retrospectively. RESULTS: A total of 111 children were included. Of these, 82 (74%) were initially evaluated by a primary care doctor, of whom 40 (49%) were referred directly to a pediatric cataract surgeon. Of 61 newborns 0-2 months of age, 9 (15%) were initially referred to an eye care provider before 6 weeks of age, but the initial evaluation by a pediatric cataract surgeon was delayed until after 6 weeks of age. Referral patterns were similar between the two institutions (P = 0.06). CONCLUSIONS: Many children with congenital of infantile cataracts are initially referred by a primary care doctor to an eye care provider who does not perform pediatric cataract surgery. Nevertheless, the majority of newborn infants with cataracts were evaluated by a pediatric cataract surgeon before 6 weeks of age.

PURPOSE: The aim of this study was to assess the effect of corneal crosslinking on vision and keratometry in children and young adults with progressive keratoconus. METHODS: A retrospective medical records review of patients aged 22 years or younger with keratoconus who underwent corneal crosslinking between January 2013 and November 2019 at Byers Eye Institute at Stanford University was conducted. Outcome measures included logarithm of the Minimum Angle of Resolution corrected distance visual acuity (CDVA); keratometry, including maximum keratometry (Kmax); pachymetry; and total wavefront aberration. Measurements were taken at baseline and at 12 and 24 months postoperatively. RESULTS: Fifty-seven eyes of 49 patients aged 12 to 22 years were assessed. The mean preoperative CDVA was logarithm of the Minimum Angle of Resolution 0.38 ± 0.32 (20/48), with a mean postoperative CDVA of 0.29 ± 0.31 (20/39) and 0.31 ± 0.31 (20/41) at 12 and 24 months postoperatively, respectively. Compared with preoperative mean Kmax, there was an improvement of -0.8 diopters (D) to a mean postoperative Kmax of 59.1 ± 9.1 D at 12 months and -1.3 D to 59.7 ± 8.8 D at 24 months. Subanalysis excluding the second eye of patients who underwent bilateral crosslinking showed similar results. Linear mixed modeling showed significant improvement in Kmax at both 12 and 24 months postoperatively. Minimum central corneal thickness initially decreased but stabilized at 24 months after crosslinking. Total wavefront aberration remained stable. CONCLUSIONS: Corneal crosslinking stabilizes, and in some cases improves, visual and corneal parameters in pediatric and young adult patients with keratoconus. The procedure is safe and well-tolerated and may prevent keratoconus progression in young patients.

BACKGROUND AND OBJECTIVE: To evaluate the social media interactions of patients who experience retinal detachment and/or repair and how ophthalmic medical providers utilize social media. PATIENTS AND METHODS: A cross-sectional study of public posts on Instagram was performed from September 2019 to January 2020, with filtering based on the following hashtags: #retinaldetachment, #detachedretina, #retinaldetachmentsurgery, and #scleralbuckle. A categorical classification system was used for each Instagram post to review descriptive variables. RESULTS: Of the 1,797 Instagram posts analyzed, 697 (39%) were made by patients, of which 395 (57%) were positive in tone and 599 (86%) were in the postoperative period. Posts by ophthalmologists were most commonly centered on colleague education (446, 81%). CONCLUSIONS: The majority of Instagram posts by patients were of a positive tone reflecting primarily on activities of daily living and rehabilitations. Retina specialists should consider providing more social media content directed toward patients, particularly regarding their rehabilitation course following retinal detachment repair.
