A Disorder of Feline Eyes Eosinophilic Keratitis By Dr. Ed Mapes Stonebridge Animal Hospital McKinney, TX

vet mckinneyEosinophilic keratitis is a disorder that affects cats. It manifests  as a pink proliferative lesion covering the cornea.  Tiny blood vessels can also be seen within the tissue on one or both eyes. The conjunctiva (pink membranes surrounding the eyes) may also appear swollen with this condition.  While this lesion is not actually painful, it progresses slowly across the eye to the point of affecting vision. Vet McKinney TX see many cases of this a year.

Note that the lesion has almost entirely covered this cornea, and conjunctiva below the lesion is quite A swollen.

Eosinophils are white blood cells that are involved in allergic reactions.  Other white cells such as lymphocytes, plasma cells, and histiocytes can also infiltrate the area and contribute to eosinophilic keratitis. Eosinophilic keratitis can be associated with a herpes virus infection, but it can also occur on its own.  Cats can also be afflicted with a skin condition called eosinophilic granuloma, which may actually be a related disorder.

When a cat has eosinophilic keratitis, vet McKinney professionals test them for the presence of several viruses before starting treatment, since corticosteroids are not usually used with herpes viral infection.  I have had success with a medication called megestrol acetate; we usually compound it into liquid form with tuna flavoring to entice felines to take their meds.

Vet McKinney professionals advise that a cat with eosinophilic keratitis be dosed daily for at least two weeks, at which time the lesion should be much improved if not entirely disappeared.  Lesions can recur, and the medication may have to be given on a maintenance basis long term to keep the corneas clear.
