Background: Ulcerative keratitis is a common condition in horses, and may leading to vision loss. The high incidence of corneal ulceration in horses is a consequence of several factors, including the large, prominent, laterally positioned eyes, naturally aggressive physical activity, and ubiquitous exposure to bacterial and fungal pathogens. Many surgical techniques have been proposed for the repair of corneal perforation, including conjunctival fl aps, keratoplastic procedures, xenografts and biological grafts. In addition, cyanoacrylate adhesives may be used for the treatment of corneal ulcers up to 3 mm in diameter. Cyanoacrylate adhesives have been used to treat small partial corneal lacerations, descemetoceles, deep stromal corneal ulcers, and recurrent corneal erosions, in both human and veterinary ophthalmology. These adhesives allow not only corneal re-epithelialization, with complete sloughing of the glue, but also negative fluorescein retention. In this report, we describe a case of a deep corneal ulcer in a horse that was treated successfully with cyanoacrylate tissue adhesive.Case: A two-month-old female Quarter Horse was referred to the Ophthalmology Section of the Veterinary Clinics Hospital of the Federal University of Rio Grande do Sul (UFRGS), Porto Alegre, RS, Brazil, presenting a deep corneal ulcer. The ophthalmic examination revealed ocular discomfort, epiph
