Photomicrographs of neovascularization in the cornea and iris. (A) The corneal epithelium shows epidermalization. Many small vascular lumina (arrows) are located in the corneal subepithelial region. (B) Small vascular lumina (arrows) are present superficially and in the surface of the iris. (C) The anterior cornea shows high expression of vascular endothelial growth factor (VEGF). (A and B, hematoxylin and eosin, original magnification, ×200; C, avidin-biotin complex immunohistochemistry, original magnification, ×200).
