Intraepithelial squamous cell carcinoma of the eye was encountered in two horses. It appeared on the conjunctiva of the left eye as a tumor of red-bean size and progressed to cover the lateral half of the cornea in about 3 months in a Thoroughbred stallion 16 years old produced in Ireland. It developed on the nictitating membrane of the right eye as a tumor of red-bean size in a Clydesdale stallion 10 years old produced in New Zealand. It was removed surgically in both horses under general anesthesia. Neither recurrenc e nor dysfunction was observed in these horses more than 6 months after operation.<BR>Biopsy on both cases revealed abnormal cornification of the middle layer of the epithelium, abnormality in cell division, and the appearance of clumping cells.
