Abnormal cornea morphology Corneal neovascularization 2012-04-03T07:15:37Z Corneal vascularization Corneal neovascularisation SNOMEDCT_US:19161004 UMLS:C0085109 New blood vessels, which sprout from the capillaries and venules of the pericorneal plexus, may block light, compromise visual acuity, and lead to inflammation, corneal scarring, and edema. Corneal neovascularization may be a consequence of corneal hypoxia. Neovascular patterns can be separated into three clinical groups: deep neovascularization overlying Descemet's membrane (seen in herpetic and luetic interstitial keratitis), stromal neovascularization (as a result of stromal keratitis), and vascular pannus (from ocular surface disorders). Corneal pannus is subepithelial fibrovascular tissue ingrowth from the limbus onto the cornea that can be observed with corneal neovascularization.
