Article Abstract
Retinal ischemia-reperfusion (I/R) is involved in the pathogenesis of many vision-threatening diseases. circRNAs act as key players in gene regulation and human diseases. However, the global circRNA expression profile in retinal I/R injury has not been fully uncovered. Herein, we established a murine model of retinal I/R injury and performed circRNA microarrays to identify I/R-related circRNAs. 1265 differentially expressed circRNAs were identified between I/R retinas and normal retinas. Notably, the detection of cWDR37 level in aqueous humor could discriminate glaucoma patients from cataract patients (AUC = 0.9367). cWdr37 silencing protected against hypoxic stress- or oxidative stress-induced retinal ganglion cell (RGC) injury. cWdr37 silencing alleviated IR-induced retinal neurodegeneration as shown by increased NeuN staining, reduced retinal reactive gliosis, and decreased retinal apoptosis. Collectively, this study provides a novel insight into the pathogenesis of retinal I/R injury. cWdr37 is a promising target for the diagnosis or treatment of I/R-related ocular diseases.

Posterior segment diseases are a leading cause of irreversible blindness and remain challenging to treat with current therapies. Blood-derived products have emerged as promising regenerative tools due to their anti-inflammatory, neuroprotective, and regenerative properties. This review synthesizes evidence from 46 clinical studies published between 2019 and 2025, covering 1253 patients and 1570 eyes treated with platelet-rich derivatives for ocular fundus diseases.

Background: Glaucoma is a leading cause of blindness characterized by retinal ganglion cell (RGC) degeneration. SA-10, a dual-acting compound with ROS scavenging and NO-donating properties, was evaluated to enhance RGC survival and function in models of oxidative stress, ischemia/reperfusion (I/R) injury, and neurotrophic factor (NF) deprivation.
Methods: SA-10-loaded nanoparticles (SA-10-NP) with a size of 279.

Neuronal nuclei (NeuN), also known as Rbfox3, is a widely used neuronal marker for identifying postmitotic neurons in both basic neuroscience and diagnostic neuropathology. Since its discovery, NeuN immunoreactivity has enabled accurate neuron counting, injury assessment, and anatomical mapping. However, accumulating evidence demonstrates that NeuN is not universally expressed across all mature neurons.

The purpose of this study was to assess the retinal relative peripheral refraction (RPR) in children with low myopia and pre-myopia, and investigate the differences in RPR using multispectral refraction topography (MRT). Ninety-five children were enrolled in the Department of Ophthalmology, Jinshan Hospital affiliated to Fudan University. MRT could measure total RPR (TRPR) of the 53° range centered on macular fovea.

Background: Glaucoma is the leading cause of irreversible vision impairment worldwide. However, the mechanisms underlying primary open-angle glaucoma (POAG), the most common form of glaucoma, are not yet fully understood.
Methods: Single-cell RNA sequencing (scRNA-seq), bulk RNA sequencing, and ATAC-seq datasets (GSE203499, GSE212186, GSE241782, GSE212188) containing data from glaucoma and control samples were analyzed to identify differentially expressed genes (DEGs) and chromatin accessibility changes.
