Background: As myopia reaches epidemic levels worldwide, its role in driving vision-threatening retinal complications is increasingly urgent. This study quantifies the burden of myopia by examining its association with key retinal diseases and how risk escalates with increasing severity.
Methods: We conducted a retrospective cohort study using the STARR clinical data warehouse, including all patients with ≥1 documented eye visit. Myopia severity was defined by spherical equivalent and axial length, classifying patients as non-myopic, myopic, highly myopic, or severely myopic. Primary outcomes included six retinal diseases associated with myopia: choroidal neovascularization (CNV), myopic macular degeneration (MMD), foveoschisis, macular hole (MH), rhegmatogenous retinal detachment (RRD), and foveal retinal detachment (FRD). Adjusted logistic regression estimated odds by myopia severity and spherical equivalent. Mean age at diagnosis was compared across groups.
Results: Retinal complications occurred at younger ages with increasing myopia severity. Compared to non-myopes, myopic, highly myopic, and severely myopic patients had 2.45 (95% CI: 2.36-2.55), 2.46 (95% CI: 2.31-2.62), and 8.15 (95% CI: 7.17-9.27) times higher odds, respectively, of developing any retinal complication. Per diopter increase in myopia, the odds of each complication increased: CNV (OR 1.11; 95% CI: 1.09-1.12), MMD (OR 1.22; 95% CI: 1.18-1.25), foveoschisis (OR 1.22; 95% CI: 1.16-1.28), MH (OR 1.06; 95% CI: 1.05-1.08), FRD (OR 1.23; 95% CI: 1.16-1.32), and RRD (OR 1.10; 95% CI: 1.10-1.11). In severe myopes, odds were markedly elevated: CNV (OR 22.90), MMD (OR 60.19), foveoschisis (OR 102.98), MH (OR 6.69), FRD (OR 22.72), and RRD (OR 6.84).
Conclusions: Myopia is independently associated with higher odds of retinal diseases, and this risk increases incrementally with severity. These findings support a dose-response relationship and highlight the importance of early risk stratification, tailored monitoring, and timely referral in patients with high and severe myopia.

In the visual cortices, receptive fields (RFs) are arranged in a gradient from small sizes in the center of the visual field to the largest sizes at the periphery. Using functional magnetic resonance imaging (fMRI) mapping of population RFs, we investigated RF adaptation in V1, V2, and V3 in patients after long-term photoreceptor degeneration affecting the central (Stargardt disease [STGD]) and peripheral (Retinitis Pigmentosa [RP]) regions of the retina. In controls, we temporarily limited the visual field to the central 10° to model peripheral loss.

Proliferative retinopathy is a leading cause of irreversible blindness in humans; however, the molecular mechanisms behind the immune cell-mediated retinal angiogenesis remain poorly elucidated. Here, using single-cell RNA sequencing in an oxygen-induced retinopathy (OIR) model, we identified an enrichment of sorting nexin (SNX)-related pathways, with SNX3, a member of the SNX family that is involved in endosomal sorting and trafficking, being significantly upregulated in the myeloid cell subpopulations of OIR retinas. Immunostaining showed that SNX3 expression is markedly increased in the retinal microglia/macrophages of mice with OIR, which is mainly located within and around the neovascular tufts.

Introduction: The definition of Leber's hereditary optic neuropathy (LHON) does not take into account a preclinical phase during which the thickness of retinal nerve fiber layer (RNFL) is increased, prior to optic nerve atrophy, reducing the chances of visual recovery.
Objectives: Search for a metabolomic signature characterizing this preclinical phase and identify biomarkers predicting the risk of LHON onset.
Methods And Results: The blood and tear metabolomic profiles of 90 asymptomatic LHON mutation carriers followed for one year will be explored as a function of RNFL thickness and compared to those of a healthy control.

Lutein is a plant pigment beneficial for eye health and for preventing retinal-related diseases. However, lutein is unstable, with low oral bioavailability. In this study, lutein fromwas loaded into cubosome lipid nanocarriers, both neutral (lutein-MO) and cationic (lutein-MO-DOTAP); the release, stability, and retinal penetration of the drug were improved.

Objectives: To provide insights into the financial burden and opportunity cost of vision loss from retinitis pigmentosa (RP) in the US by using net present value (NPV) of direct medical and nonmedical costs.
Methods: Assumptions, including economic (discount rate, median income, cost-of-living, Social Security and Medicare taxes, public insurance/supplemental benefits, nutrition assistance, and prescription drug assistance), medical (federal National Health Expenditure tables, a recent retrospective claims analysis, and Optum Health claims database) and demographic (mortality rate, increase in mortality due to visual impairment, progression of blindness, probability of survival, retirement rate, rate of disability, and RP diagnosis probability) were made to develop a NPV model. Scenario analyses were performed on benefits and costs arising from patients with RP, if vision could be preserved via novel gene therapies.
