Quantitative analysis of retinal and choroidal microvascular changes in patients with diabetes

Scientific Reports, 2018
The relationship between choroidal and retinal microvascular changes has not yet been well described, and there were limited data on diagnostic ability of optical coherence tomography (OCT)-derived vascular parameters for determining diabetic retinopathy

Choroidal vascularity index changes with phacovitrectomy for vitreoretinal interface disorders

Indian Journal of Ophthalmology, 2022
Purpose: Vitreomacular interface disorders have long been argued to change choroidal structure. The aim of this study was to determine the choroidal vascularity index (CVI) changes following internal limiting membrane peeling for epiretinal membrane (ERM)

Microglial TSPAN4‐Dependent Migrasomes Promote Pathological Retinal Neovascularization via Immune‐Vascular Crosstalk

Advanced Science, EarlyView.
Combined high‐glucose and hypoxic stress switches microglia into a TSPAN4‐dependent migrasome‐producing state. These migrasomes deliver pro‐angiogenic signals to endothelial cells, activating HIF‐1α/VEGF signaling, disrupting vascular junctions, and fueling pathological neovascularization. This work uncovers migrasome‐mediated immune‐vascular crosstalk
