Anti-VEGF Antibody Leads to Later Atypical Intravitreous Neovascularization and Activation of Angiogenic Pathways in a Rat Model of Retinopathy of Prematurity

Purpose. Inhibiting VEGF improves adult retino/choroido-vascular diseases, but can lead to recurrent intravitreous neovascularization (IVNV), avascular retina (AVA), and retinal detachment in preterm infants with retinopathy of prematurity (ROP). We sought to understand causes of late-onset IVNV and AVA following anti-VEGF using an ROP model.
