Müller Glia–Vasculature Interactions in the Developing Retina

Glia, Volume 74, Issue 10, October 2026.
Retinal vascular layers form normally despite loss of cholinergic retinal waves. Müller glial processes contact endothelial tip cells early and form Aquaporin‐4‐enriched endfeet. Glial endfoot calcium signals are compartmentalized and occur largely independently of neural activity. ABSTRACT Coordinated signaling among neurons, glia, and the vasculature

DNA Origami Uptake in Y‐79 Retinoblastoma Cells Driven by Oligolysine Coating

Small Structures, Volume 7, Issue 10, October 2026.
We show that polymeric coating can enable DNA origami nanoparticle internalization into ocular retinoblastoma cells. Not only are the coated nanoparticles well‐tolerable to the cells, but they also remain mobile in the vitreous of a porcine ex vivo model.

Insights into the modulation of age‐related macular degeneration: Molecular and systems‐level perspectives

Acta Ophthalmologica, Volume 104, Issue S293, Page S4-S35, October 2026.
ENGLISH SUMMARY In developed countries, age‐related macular degeneration (AMD) is the leading cause of visual impairment in the aging population. Understanding of its pathogenesis is limited and the number of patients is predicted to continue rising. AMD is classified into two main forms: dry and neovascular AMD (dAMD and nAMD, respectively).

Effect of chronic high‐altitude hypoxia on retinal vascular phenotype, choroidal and retinal vasoreactivity in Peruvian highlanders

Experimental Physiology, Volume 111, Issue 10, Page 4814-4826, 1 October 2026.
Abstract High‐altitude chronic hypoxia can induce excessive erythrocytosis (EE, defined as a haemoglobin concentration of ≥21 g/dL in men), leading to hyperviscosity and promoting endothelial dysfunction. We aimed to assess whether EE affects the retinal vascular phenotype and the ophthalmological vascular response to CO2.

Grid-based analysis of three-dimensional choroidal Sattler’s and Haller’s layer vascularity volume index and its relation to age and axial length in adults by ultra-widefield swept-source optical coherence tomography angiography

BMC Ophthalmology
Background This study was to evaluate the features of choroidal Sattler’s and Haller’s layer (CSHL) vessels in adults and explore its relationship with factors such as age, axial length (AL) and body mass index (BMI) by using ultra-widefield swept-source
