Entropion is the inward rolling of all or part of an eyelid. The cornea and conjunctiva are irritated by hairs on the eyelid causing problems from mild discomfort and tearing to chronic pain and eye injury. Entropion is more common in dogs than cats, but may be under-recognized in cats. In this study from the U.K., 50 cats with entropion were examined. About 1/3 of the cats had a mean age of 4 years, while the remainder of the cats were relatively older, with a mean age of 11 years. Among the younger cats, entropion was likely to be caused by a pre-existing irritative disorder, such as conjunctivitis or corneal ulceration. In the group of older cats, lid laxity or enophthalmos were more likely causes. Persian cats represented 10% and Maine Coons represented 6% of the study group. Among these cats, involutional entropion was likely caused by anatomic problems. All cats were treated surgically with a Hotz-Celsus procedure, and the results were evaluated from 4 to 22 weeks later. Surgical treatment was curative in the majority of cases. [SL]
