The glaucomas are a group of conditions leading to irreversible sight loss and characterised by progressive loss of retinal ganglion cells. Although not always elevated, intraocular pressure is the only modifiable risk factor demonstrated by large clinical trials. It remains the leading cause of irreversible blindness, but timely treatment to lower intraocular pressure is effective at slowing the rate of vision loss from glaucoma. Methods for lowering intraocular pressure include laser treatments, topical medications, and surgery. Although modern surgical innovations aim to be less invasive, many have been introduced with little supporting evidence from randomised controlled trials. Many cases remain undiagnosed until the advanced stages of disease due to the limitations of screening and poor access to opportunistic case finding. Future research aims to generate evidence for intraocular pressure-independent neuroprotective treatments, personalised treatment through genetic risk profiling, and exploration of potential advanced cellular and gene therapies.
Dissing-Olesen L, Walker AJ, Feng Q, Barr HJ, Walker AC, Xie L, Wilton DK, Das I, Benowitz LI, Stevens B. FEAST: A flow cytometry-based toolkit for interrogating microglial engulfment of synaptic and myelin proteins. Nat Commun 2023;14(1):6015.Abstract
Although engulfment is a hallmark of microglia function, fully validated platforms that facilitate high-throughput quantification of this process are lacking. Here, we present FEAST (Flow cytometric Engulfment Assay for Specific Target proteins), which enables interrogation of in vivo engulfment of synaptic material by brain resident macrophages at single-cell resolution. We optimize FEAST for two different analyses: quantification of fluorescent material inside live cells and of engulfed endogenous proteins within fixed cells. To overcome false-positive engulfment signals, we introduce an approach suitable for interrogating engulfment in microglia from perfusion-fixed tissue. As a proof-of-concept for the specificity and versatility of FEAST, we examine the engulfment of synaptic proteins after optic nerve crush and of myelin in two mouse models of demyelination (treatment with cuprizone and injections of lysolecithin). We find that microglia, but not brain-border associated macrophages, engulf in these contexts. Our work underscores how FEAST can be utilized to gain critical insight into functional neuro-immune interactions that shape development, homeostasis, and disease.
Azad AD, Yuan M, Weinert M, Rosenblatt TR, Miller JW, Lorch A. The Transition to Ophthalmology Residency: A National Survey of the Combined Ophthalmology PGY-1 Program. J Acad Ophthalmol (2017) 2023;15(2):e188-e196.Abstract
Background  In 2017, the Accreditation Council for Graduate Medical Education announced all ophthalmology residency programs would provide a combined transitional or joint preliminary program for first postgraduate year (PGY-1) residents, with mandatory implementation by 2023. Purpose  This study aimed to survey ophthalmology residency program directors, postgraduate year 2 (PGY-2) ophthalmology residents who were a part of the first, official combined ophthalmology PGY-1 year, and postgraduate year 3 (PGY-3) residents who were a PGY-1 resident the year prior to integration to evaluate characteristics and perspectives on the combined ophthalmology PGY-1 year. Methods  A national, internet survey-based study approved by the Association of University Professors of Ophthalmology (AUPO) was disseminated to the AUPO listserv of program directors (PDs) and PGY-2 and PGY-3 ophthalmology residents from July to August 2022 and then again April to June 2023. Results  Twenty-six PDs completed the survey (response rate 20.3% out of 128 PDs). Forty-one PGY-2 ophthalmology residents who underwent the combined ophthalmology PGY-1 year and 33 PGY-3 ophthalmology residents also completed the survey. Most PGY-1 curricula focused on exposure to comprehensive ophthalmology and provided indirect ophthalmoscope, slit lamp, and refraction skills training to residents. Early exposure to fundamentals and clinical workflows were commonly cited benefits to the integration. When PDs were surveyed about how well-prepared PGY-1 residents who went through the combined year are for the PGY-2 relative to the prior year's class, 16 (61.5%) responded "better prepared." PGY-2 residents also reported a relatively higher level of clinical preparedness and familiarity with ophthalmology co-residents than PGY-3 residents. Several areas of improvement cited by both PDs and residents were identified including a dedicated didactic curriculum and more time in ophthalmology during the PGY-1 year. Conclusions  We found an overall net benefit from the integration of the combined ophthalmology PGY-1 year. Benefits include early exposure to clinical skills and knowledge specific to ophthalmology, leading to increased confidence and preparedness for the rigorous transition to ophthalmology residency. We also identified many areas for improvement to optimize the PGY-1 year including a formal curriculum and additional time in ophthalmology. Programs should work closely with their residents, faculty, and non-ophthalmology PDs to refine the PGY-1 for the benefit of future ophthalmologists.
Chinn RN, Wilkinson CL, Staffa SJ, Michalak SM, Shoshany TN, Bishop K, Hunter DG, Gaier ED. Amblyopia treatment outcomes in patients with neurodevelopmental disorders. J AAPOS 2023;27(5):276.e1-276.e8.Abstract
PURPOSE: To compare amblyopia treatment outcomes between patients with neurodevelopmental disorders and their typically developing peers. METHODS: Of 2,311 patients diagnosed with amblyopia between 2010 and 2014 at Boston Children's Hospital, 460 met inclusion criteria (age 2-12 with anisometropic, strabismic, or mixed amblyopia [interocular difference (IOD) ≥2 lines]). Treatment and visual outcomes were analyzed according to neurodevelopmental status: neurodevelopmental delay (DD) versus typical development (TD). RESULTS: The DD group (n = 54) and TD group (n = 406) were similar in demographics, amblyogenic risk factors, baseline visual measures, prescribed therapy, and adherence (P ≥ 0.10). Between-visit follow-up time was longer for the DD group (0.65 [0.42- 0.97] years) than for the TD group (0.5 [0.36-0.82] years; P = 0.023). IOD improved similarly in each group by the last visit (DD, -0.15 logMAR [-0.31 to -0.02]; TD, -0.2 logMAR [-0.38 to -0.1]; P = 0.09). Each group reached amblyopia resolution by the last visit at similar frequencies (DD, 23/54 [43%]; TD, 211/406 [52%]; P > 0.2). DD diagnosis did not independently influence amblyopia resolution (HR, 0.77; 95% CI, 0.53-1.12; P = 0.17), but each additional month of interval time between follow-up visits reduced the likelihood of resolution by 2.7% (HR, 0.67; 95% CI, 0.51-0.87; P = 0.003). CONCLUSIONS: Patients with DD and those with TD responded similarly to amblyopia therapy; however, follow-up intervals were longer in patients with DD and correlated with the likelihood of persistent amblyopia, suggesting that greater efforts at assuring follow-up may benefit patients with DD.

APOE4 impairs the microglial response in Alzheimer's disease by inducing TGFβ-mediated checkpoints. Nat Immunol 2023;24(11):1839-1853.Abstract
The APOE4 allele is the strongest genetic risk factor for late-onset Alzheimer's disease (AD). The contribution of microglial APOE4 to AD pathogenesis is unknown, although APOE has the most enriched gene expression in neurodegenerative microglia (MGnD). Here, we show in mice and humans a negative role of microglial APOE4 in the induction of the MGnD response to neurodegeneration. Deletion of microglial APOE4 restores the MGnD phenotype associated with neuroprotection in P301S tau transgenic mice and decreases pathology in APP/PS1 mice. MGnD-astrocyte cross-talk associated with β-amyloid (Aβ) plaque encapsulation and clearance are mediated via LGALS3 signaling following microglial APOE4 deletion. In the brains of AD donors carrying the APOE4 allele, we found a sex-dependent reciprocal induction of AD risk factors associated with suppression of MGnD genes in females, including LGALS3, compared to individuals homozygous for the APOE3 allele. Mechanistically, APOE4-mediated induction of ITGB8-transforming growth factor-β (TGFβ) signaling impairs the MGnD response via upregulation of microglial homeostatic checkpoints, including Inpp5d, in mice. Deletion of Inpp5d in microglia restores MGnD-astrocyte cross-talk and facilitates plaque clearance in APP/PS1 mice. We identify the microglial APOE4-ITGB8-TGFβ pathway as a negative regulator of microglial response to AD pathology, and restoring the MGnD phenotype via blocking ITGB8-TGFβ signaling provides a promising therapeutic intervention for AD.
Lains I, Ung C, Gong D, Parikh D, Eliott D. Polychromatic Aqueous and Vitreous Crystals Due to Phacolytic Glaucoma in a Patient With Marfan Syndrome and Lens Dislocation. J Vitreoretin Dis 2023;7(5):435-439.Abstract
Purpose: To describe a patient with Marfan syndrome and crystalline lens luxation who developed phacolytic glaucoma with polychromatic crystals in the anterior chamber and vitreous. Methods: We present a retrospective case report. Results: A 58-year-old man with Marfan syndrome and crystalline lens luxation since childhood presented with 2 days of pain in the left eye. The visual acuity was 20/30 OS with an aphakic contact lens, and the intraocular pressure (IOP) was 31 mm Hg. Polychromatic crystals were evident in the anterior chamber and vitreous. The retina was attached. Despite medical treatment, the IOP remained elevated; therefore, a pars plana vitrectomy and lensectomy were performed. At the last follow-up, the IOP was normal and the retina remained attached. Conclusions: Phacolytic glaucoma can be seen in eyes with a subluxated or luxated mature or hypermature lens. In these rare cases, iridescent crystals can be observed in the aqueous and vitreous. Vitrectomy with lensectomy is the definitive treatment.
Cullen PF, Mazumder AG, Sun D, Flanagan JG. Rapid isolation of intact retinal astrocytes: a novel approach. Acta Neuropathol Commun 2023;11(1):154.Abstract
Astrocytes are a major category of glial support cell in the central nervous system and play a variety of essential roles in both health and disease. As our understanding of the diverse functions of these cells improves, the extent of heterogeneity between astrocyte populations has emerged as a key area of research. Retinal astrocytes, which form the direct cellular environment of retinal ganglion cells somas and axons, undergo a reactive response in both human glaucoma and animal models of the disease, yet their contributions to its pathology and progression remain relatively unknown. This gap in knowledge is largely a function of inadequate isolation techniques, driven in part by the sparseness of these cells and their similarities with the more abundant retinal Müller cells. Here, we present a novel method of isolating retinal astrocytes and enriching their RNA, tested in both normal and ocular hypertensive mice, a common model of experimental glaucoma. Our approach combines a novel enzyme assisted microdissection of retinal astrocytes with selective ribosome immunoprecipitation using the Ribotag method. Our microdissection method is rapid and preserves astrocyte morphology, resulting in a brief post-mortem interval and minimizing loss of RNA from distal regions of these cells. Both microdissection and Ribotag immunoprecipitation require a minimum of specialized equipment or reagents, and by using them in conjunction we are able to achieve > 100-fold enrichment of astrocyte RNA.
Alemi H, Dehghani S, Forouzanfar K, Surico PL, Narimatsu A, Musayeva A, Sharifi S, Wang S, Dohlman TH, Yin J, Chen Y, Dana R. Insights into mustard gas keratopathy- characterizing corneal layer-specific changes in mice exposed to nitrogen mustard. Exp Eye Res 2023;236:109657.Abstract
Exposure to mustard agents, such as sulfur mustard (SM) and nitrogen mustard (NM), often results in ocular surface damage. This can lead to the emergence of various corneal disorders that are collectively referred to as mustard gas keratopathy (MGK). In this study, we aimed to develop a mouse model of MGK by using ocular NM exposure, and describe the subsequent structural changes analyzed across the different layers of the cornea. A 3 μL solution of 0.25 mg/mL or 5 mg/mL NM was applied to the center of the cornea via a 2-mm filter paper for 5 min. Mice were evaluated prior to and after exposure on days 1, 3, 7, 14, and 28 for 4 weeks using slit lamp examination with fluorescein staining. Anterior segment optical coherence tomography (AS-OCT) and in vivo confocal microscopy (IVCM) tracked changes in the epithelium, stroma, and endothelium of the cornea. Histologic evaluation was used to examine corneal cross-sections collected at the completion of follow-up. Following exposure, mice experienced central corneal epithelial erosion and thinning, accompanied by a decreased number of nerve branches in the subbasal plexus and increased activated keratocytes in the stroma in both dosages. The epithelium was recovered by day 3 in the low dose group, followed by exacerbated punctuate erosions alongside persistent corneal edema that arose and continued onward to four weeks post-exposure. The high dose group showed persistent epitheliopathy throughout the study. The endothelial cell density was reduced, more prominent in the high dose group, early after NM exposure, which persisted until the end of follow-up, along with increased polymegethism and pleomorphism. Microstructural changes in the central cornea at 4 weeks post-exposure included dysmorphic basal epithelial cells and reduced epithelial thickness, and in the limbal cornea included decreased cellular layers. We present a mouse model of MGK using NM that successfully replicates ocular injury caused by SM in humans who have been exposed to mustard gas.

Retinal ganglion cell repopulation for vision restoration in optic neuropathy: a roadmap from the RReSTORe Consortium. Mol Neurodegener 2023;18(1):64.Abstract
Retinal ganglion cell (RGC) death in glaucoma and other optic neuropathies results in irreversible vision loss due to the mammalian central nervous system's limited regenerative capacity. RGC repopulation is a promising therapeutic approach to reverse vision loss from optic neuropathies if the newly introduced neurons can reestablish functional retinal and thalamic circuits. In theory, RGCs might be repopulated through the transplantation of stem cell-derived neurons or via the induction of endogenous transdifferentiation. The RGC Repopulation, Stem Cell Transplantation, and Optic Nerve Regeneration (RReSTORe) Consortium was established to address the challenges associated with the therapeutic repair of the visual pathway in optic neuropathy. In 2022, the RReSTORe Consortium initiated ongoing international collaborative discussions to advance the RGC repopulation field and has identified five critical areas of focus: (1) RGC development and differentiation, (2) Transplantation methods and models, (3) RGC survival, maturation, and host interactions, (4) Inner retinal wiring, and (5) Eye-to-brain connectivity. Here, we discuss the most pertinent questions and challenges that exist on the path to clinical translation and suggest experimental directions to propel this work going forward. Using these five subtopic discussion groups (SDGs) as a framework, we suggest multidisciplinary approaches to restore the diseased visual pathway by leveraging groundbreaking insights from developmental neuroscience, stem cell biology, molecular biology, optical imaging, animal models of optic neuropathy, immunology & immunotolerance, neuropathology & neuroprotection, materials science & biomedical engineering, and regenerative neuroscience. While significant hurdles remain, the RReSTORe Consortium's efforts provide a comprehensive roadmap for advancing the RGC repopulation field and hold potential for transformative progress in restoring vision in patients suffering from optic neuropathies.
Oke I, Lutz SM, Hunter DG, Galbraith AA. Vision Screening Among Children With Private Insurance: 2010-2019. Pediatrics 2023;152(3)Abstract
OBJECTIVES: To describe trends in vision screening based on insurance claims for young children in the United States. METHODS: This cross-sectional study used administrative claims data from the 2010-2019 IBM MarketScan Commercial Claims and Encounters Database. We included children aged 1 to <5 years at the beginning of each calendar year. The primary outcome was a vision screening claim within 12 months for chart-based or instrument-based screening. Linear regression was used to evaluate trends over time in vision screening claims and practitioner payment. RESULTS: This study included a median of 810 048 (interquartile range, 631 523 - 1 029 481) children between 2010 and 2019 (mean [standard deviation] age, 2.5 [1.1] years; 48.7% female). The percentage of children with vision screening claims increased from 16.7% in 2010 to 44.3% in 2019 (difference, 27.5%; 95% confidence interval, 27.4% to 27.7%). Instrument-based screening claims, which were identified in <0.2% of children in 2010, increased to 23.4% of children 1 to <3 years old and 14.4% of children 3 to <5 years old by 2019. From 2013 to 2018, the average of the median practitioner payment for instrument-based screening was $23.70, decreasing $2.10 per year during this time (95% confidence interval, $0.85 to $3.34; P = .009). CONCLUSIONS: Vision screening claims among young children nearly tripled over the last decade, and this change was driven by increased instrument-based screening for children aged <3 years. Further investigation is needed to determine whether the decreasing trends in practitioner payment for screening devices will reduce the adoption of vision screening technology in clinical practice.

Evaluating the Diagnostic Accuracy and Management Recommendations of ChatGPT in Uveitis. Ocul Immunol Inflamm 2023;:1-6.Abstract
INTRODUCTION: Accurate diagnosis and timely management are vital for favorable uveitis outcomes. Artificial Intelligence (AI) holds promise in medical decision-making, particularly in ophthalmology. Yet, the diagnostic precision and management advice from AI-based uveitis chatbots lack assessment. METHODS: We appraised diagnostic accuracy and management suggestions of an AI-based chatbot, ChatGPT, versus five uveitis-trained ophthalmologists, using 25 standard cases aligned with new Uveitis Nomenclature guidelines. Participants predicted likely diagnoses, two differentials, and next management steps. Comparative success rates were computed. RESULTS: Ophthalmologists excelled (60-92%) in likely diagnosis, exceeding AI (60%). Considering fully and partially accurate diagnoses, ophthalmologists achieved 76-100% success; AI attained 72%. Despite an 8% AI improvement, its overall performance lagged. Ophthalmologists and AI agreed on diagnosis in 48% cases, with 91.6% exhibiting concurrence in management plans. CONCLUSIONS: The study underscores AI chatbots' potential in uveitis diagnosis and management, indicating their value in reducing diagnostic errors. Further research is essential to enhance AI chatbot precision in diagnosis and recommendations.
Liu WW, Kinzy TG, Cooke Bailey JN, Xu Z, Hysi P, Wiggs JL, Wiggs JL. Mechanosensitive ion channel gene survey suggests potential roles in primary open angle glaucoma. Sci Rep 2023;13(1):15871.Abstract
Although glaucoma is a disease modulated by eye pressure, the mechanisms of pressure sensing in the eye are not well understood. Here, we investigated associations between mechanosensitive ion channel gene variants and primary open-angle glaucoma (POAG). Common (minor allele frequency > 5%) single nucleotide polymorphisms located within the genomic regions of 20 mechanosensitive ion channel genes in the K2P, TMEM63, PIEZO and TRP channel families were assessed using genotype data from the NEIGHBORHOOD consortium of 3853 cases and 33,480 controls. Rare (minor allele frequency < 1%) coding variants were assessed using exome array genotyping data for 2606 cases and 2606 controls. Association with POAG was analyzed using logistic regression adjusting for age and sex. Two rare PIEZO1 coding variants with protective effects were identified in the NEIGHBOR dataset: R1527H, (OR 0.17, P = 0.0018) and a variant that alters a canonical splice donor site, g.16-88737727-C-G Hg38 (OR 0.38, P = 0.02). Both variants showed similar effects in the UK Biobank and the R1527H also in the FinnGen database. Several common variants also reached study-specific thresholds for association in the NEIGHBORHOOD dataset. These results identify novel variants in several mechanosensitive channel genes that show associations with POAG, suggesting that these channels may be potential therapeutic targets.
Cavuoto KM, Binenbaum G, Chang MY, Heidary G, Morrison DG, Trivedi RH, Kim SJ, Pineles SL. Genetic testing for infantile nystagmus syndrome with or without associated findings. J AAPOS 2023;27(5):259-264.Abstract
PURPOSE: To review the published literature assessing the clinical utility of genetic testing in individuals with infantile nystagmus syndrome (INS), defined as binocular conjugate nystagmus and onset prior to 6 months of age, with or without associated findings. METHODS: A literature search was last conducted in October 2022. The results were limited to articles published in English. The search yielded 517 abstracts, of which 72 papers were reviewed in full text. Of these papers, 4 met the criteria for inclusion and were graded by a study methodologist. RESULTS: The 4 studies that met inclusion criteria used next-generation sequencing with gene panels ranging from 31 to 336 genes. The overall molecular diagnostic rate ranged from 35% to 60% in the included studies, although the yield was higher when genetic testing was guided by clinical phenotyping (approximately 80%) and in the subsets of patients with a family history (up to 88%). As many as 30% of patients tested had a reclassification of the diagnosis based on the genetic testing results. CONCLUSIONS: Genetic testing has the potential to provide a definitive diagnosis and identify treatable conditions in patients presenting with INS, especially when considered in conjunction with clinical phenotyping and family history.
Gomes PJ, Ciolino JB, Arranz P, Gonzalo A, Fernández N, Hernández G. Bilastine 0.6% preservative-free eye drops, an effective once-daily treatment to reduce signs and symptoms of allergic conjunctivitis: A pooled analysis of two randomized clinical trials. J Investig Allergol Clin Immunol 2023;Abstract
BACKGROUND AND OBJECTIVE: Allergic conjunctivitis is the most common type of ocular allergy. The objective of this study was to evaluate the efficacy of a new once-daily, preservative-free, bilastine 0.6% eye drop formulation for the treatment of allergic conjunctivitis. METHODS: Two double-masked, vehicle controlled, clinical studies (a Phase 2 Dose Ranging Study and a Phase 3 Efficacy Study) were conducted to assess the efficacy of bilastine ophthalmic solution for the treatment of signs and symptoms of allergic conjunctivitis. Both studies used the Ora-CAC® Conjunctival Allergen Challenge (CAC) Model to allow observations of allergic responses under controlled conditions. Each study was analyzed separately and then combined to create an integrated dataset. RESULTS: Efficacy was achieved for the primary efficacy endpoint of ocular itching for three bilastine concentrations (0.2%, 0.4%, and 0.6%) at 15 minutes and 8 hours post-instillation and bilastine 0.6% ophthalmic solution was also efficacious at 16 hours post-instillation. Bilastine 0.6% ophthalmic solution demonstrated non-inferiority to ketotifen 0.025% at the onset of action. From the integrated data set, differences between vehicle and bilastine 0.6% were significant at all time points both at onset (15 minutes) and at a prolonged duration (16 hours) after instillation. CONCLUSION: This multi-trial assessment suggests that bilastine 0.6% ophthalmic solution is efficacious for the treatment of the signs and symptoms of allergic conjunctivitis, with a rapid and prolonged duration of action, and has a favorable safety profile. The added convenience of a once-a-day dosing regimen may contribute to patient adherence and improve their quality of life.
Vakharia JD, Muhammed M, Remba-Shapiro I, Marsiglia M, Hadaway N, Chwalisz BK, Nachtigall LB. A novel approach to hypophysitis: outcomes using non-glucocorticoid immunosuppressive therapy. Eur J Endocrinol 2023;189(3):309-317.Abstract
OBJECTIVE: To determine pituitary function before and after nonglucocorticoid immunosuppressive therapy (NGIT) in subjects with hypophysitis and evaluate their clinical and radiologic outcomes. DESIGN: Retrospective, longitudinal study. METHODS: We reviewed a large database, selected subjects with hypophysitis treated with NGIT, and collected information on the duration of therapy, and clinical, hormonal, and radiologic outcomes. RESULTS: Twelve subjects met the inclusion criteria. Five subjects had primary hypophysitis (PH), while seven had secondary hypophysitis (SH) due to an underlying systemic inflammatory disease. Mean age ± SD was 48.0 ± 15.7 years and 40.9 ± 13.0 years, for PH and SH, respectively. The majority were female (PH 60% and SH 86%). BMI ± SD at presentation was 25.2 ± 2.5 kg/m2 and 26.8 ± 6.7 kg/m2 for PH and SH, respectively. The most common symptom at presentation was fatigue (75%). All PH subjects (100%) and 2 (28.6%) SH subjects had polyuria/polydipsia. There was a significant decrease in mean pituitary stalk thickness after NGIT (P = .0051) (mean duration 16.5 ± 4.8 months). New hormone loss or recovery occurred rarely. Mycophenolate mofetil was the most used NGIT: adverse effects prompted discontinuation in 2 out of 7 subjects. CONCLUSIONS: Subjects with hypophysitis receiving NGIT had stable or improved brain/pituitary magnetic resonance imaging findings with a significant decrease in pituitary stalk thickness. NGITs did not improve anterior pituitary function. Our findings suggest that NGIT may be considered as an alternative therapy for patients with hypophysitis who require immunosuppression.
