Retinal microglia protect against vascular damage in a mouse model of retinopathy of prematurity

Frontiers in Pharmacology, 2022
Retinopathy of prematurity (ROP) is a common cause of blindness in preterm babies. As a hypoxia-induced eye disease characterized by neovascularization, its association with retinal microglia has been noted but not well documented.
