Common indications for intraocular anti-VEGF injections
The most common indications for intraocular anti-vascular endothelial growth factor (VEGF) injections include exudative age-related macular degeneration, background and proliferative diabetic retinopathy, branch and central retinal vein occlusions, and retinopathy of prematurity. Intraocular anti-VEGF drugs generally work through two mechanisms: 1. Decreasing vascular permeability allows absorption of edema. 2. Decreasing neovascularization prevents hemorrhages and tissue distortion caused by fibrous proliferation. RPE indicates retinal pigment epithelium.
