title: Keratinization of the conjunctiva.
abstract: Keratinization of the tarsal conjunctiva in an eye with adequate tears occurs following a number of conditions, including irritation and sensitivity to topical medications, Stevens-Johnson syndrome, radiation to the lid, and occasionally from unknown causes. The keratinized cells produce an epithelial keratitis with subsequent vascularization of the cornea. The morphogenesis of this condition is discussed, along with therapy including mucous membrane grafts and freezing of the tissue.
