Drug effects on the neovascularization response to silver nitrate cauterization of the rat cornea

Abstract

Neovascular growth into the cornea induced by silver nitrate cauterization is the basis of this experimental model developed to test potential antiinflammatory drugs for ocular use. Cauterization of the rat cornea with a silver nitrate applicator stick provides the stimulus for neovascularization, which is scored by a blinded investigator. Burn stimulus intensity is also scored to substantiate a consistent stimulus among the groups. Compounds showing activity in this model include topical dexamethasone, prednisolone, ticabesone propionate, ketorolac, and phenidone. This model is presented as a practical method for testing antiinflammatory drugs in the eye.
