Background: Intrastromal corneal cysts are uncommon lesions caused by the implantation of corneal epithelial cells in the stroma, and their subsequent intrastromal proliferation, which has often been secondary to trauma. Lamellar keratectomy has been the chosen treatment and diagnosis has been confi rmed by histopathology. In this report, we describe a case of corneal epithelial inclusion cyst in a dog that was successfully treated with lamellar keratectomy.Case A 10 year old Yorkshire Terrier dog was referred to the Ophthalmology Section of the Veterinary Clinics Hospital of the Federal University of Rio Grande do Sul (UFRGS), presenting an abnormal appearance in the left cornea. The ophthalmic examination revealed a white and elevated mass, measuring approximately 3 mm in the left cornea. Thus, a superficial keratectomy was performed by utilizing an angled ophthalmic disc knife, under general anesthesia, and an operating microscope. In addition, a third eyelid fl ap was performed to protect the cornea. The postoperative treatment involved broad-spectrum antibiotic containing tobramycin 0.3%, and a non-steroidal anti-inflammatory solution of sodium diclofenac 0.1%, administered six times a day for two weeks.
