Plain-English summary
An 8-year-old male Gypsy Vanner horse was taken to the University of Florida for problems with his right eye, specifically recurring corneal ulcers, which are sores on the eye's surface. During the examination, the vets found a group of unusual hairs growing along the edge of the horse's third eyelid, which is a protective fold of tissue. They surgically removed this part of the eyelid, and tests showed that the hair growth was a dermoid, a type of abnormal tissue. After the surgery, the horse's eye condition improved significantly, and he was doing well at a follow-up check six months later.
Abstract
An 8-year-old Gypsy Vanner gelding presented to the University of Florida Ophthalmology service for the evaluation of chronic, recurrent corneal ulcers behind the third eyelid of the right eye. On ophthalmic examination, a cluster of aberrant hairs was identified growing along the margin of the third eyelid. This portion of third eyelid was surgically excised, and histopathology identified the haired tissue as a dermoid. Chronic keratitis secondary to a third eyelid dermoid was diagnosed, and excision appeared curative at 6 months post-operative follow-up.
