Treatments for Wet AMD: Anti-VEGF
Vascular endothelial growth factor
Vascular endothelial growth factor, originally known as vascular permeability factor, is a signal protein produced by cells that stimulates the formation of blood vessels. To be specific, VEGF is a sub-family of growth factors, the platelet-derived growth factor family of cystine-knot growth factors. They are important signaling proteins involved in both vasculogenesis and angiogenesis.
