title: [Morphological study of experimental corneal neovascularization after anterior uveal ischemia].
abstract: We morphologically investigated what kinds of inflammatory cells infiltrate the corneoscleral limbus by light and electron microscopy and what manner of keratocytes and vascular endothelial cells appear at the corneal limbus, when the corneal edema was aggravated severely and clinical corneal new vessels were found initially, i.e. until three days after anterior segmental ischemia in rabbit eyes. The majority of infiltrating inflammatory cells were polymorphonuclear leukocytes and the others were lymphocytes and histiocytes etc. Peripheral keratocytes around limbal vessels were stimulated and transformed to fibroblastic cells as a result of anterior segment ischemia. Proliferating endothelial cells of comparatively minor limbal vessels invaded between corneal lamellar layers toward the corneal center. Polymorphonuclear leukocytes were often found near activated keratocytes proliferating vascular endothelial cells, hear and there. Consequently, it is considered that the stimulated polymorphonuclear leukocytes play an important role when corneal neovascularization occurs after anterior segmental ischemia.
