Corneal neovascularization results from disorders of the cornea or insults to the cornea, including degeneration, ischemia, inflammation, infection, or trauma, that promote an imbalance of angiogenic factors such as vascular endothelial growth factor (VEGF), platelet-derived growth factor (PDGF), pigment epithelium derived factor, angiostatin, and endostatin [4–6]. This evidence concerns the gene VEGFA and ischemia.
