Corneal neovascularization is the excessive ingrowth of blood vessels from the limbal vascular plexus into the cornea, caused by deprivation of oxygen from the air. ==Pathogenesis== Chemical theory: There may be presence of vasostimulatory factor (VSF) or the breakdown (destruction) of previously existing vasoinhibitory factor (VIF). Mechanical theory: Blood vessels cannot invade normal cornea because of its compactness and loosening of the compactness of corneal tissue due to oedema was mandatory for neovascularization. Combined chemical and mechanical theory: Both release of some vasostimulatory factor (VSF) and structural loosening of compact corneal stroma by oedema are necessary for the neovascularization to occur. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Corneal neovascularization」の詳細全文を読む スポンサード リンク
