Eosinophilic keratitis and keratoconjunctivitis in a 7-year-old domestic shorthaired cat.

A 7-year-old, spayed female, domestic shorthair was presented with a several-month history of an ulcerated right cornea with marked stromal edema and inflammation that was nonresponsive to therapy. A diagnosis of eosinophilic keratitis was made, based on cytologic examination of corneal scrapings. The lesion resolved after treatment with topical corticosteroids.
