A 1-year-old Dutch Warmblood gelding was presented to the University of Florida’s Large Animal Hospital (UF-LAH) for correction of ectropion of the right lower eyelid. The ectropion was the result of a lower eyelid laceration. A primary repair was performed by the referring veterinarian; however, the horse prematurely removed the sutures and the wound healed with inversion of the eyelid margin. Surgical correction of the entropion, with removal of tissue from the lower eyelid, resulted in cicatricial ectropion. During the initial evaluation at UF-LAH, a corneal ulcer was noted in the right eye because of exposure from the anatomically nonfunctional lower eyelid. A modified Kuhnt–Szymanowski procedure was performed to correct the ectropion and repair the eyelid margin. The surgical site healed appropriately with an acceptable cosmetic and functional result. No recurrences of corneal ulcers in the right eye were reported in the 18 months following surgical correction of the ectropion.
