Medical Definition of Corneal neovascularization
1. New blood vessels originating from the corneal veins and extending from the limbus into the adjacent corneal stroma. These vessels may lie in the superficial and/or deep corneal stroma. Neovascularization is a sequel to numerous inflammatory diseases of the ocular anterior segment, including trachoma, viral interstitial keratitis, microbial keratoconjunctivitis, and the immune response elicited by corneal transplantation.
