A 15-year-old female spayed domestic short-hair cat was referred for a nonpigmented mass within the pupil of the left eye. In the ophthalmic examination, the non-pigmented mass appeared behind the iris. Visual function was normal, and there were no significant clinical findings except the ciliary body mass. Seven days after presentation, the mass was removed with sclerotomy and iridocyclectomy. The mass was determined to be an iridociliary epithelial tumor upon histopathological and immunohistochemical analyses. Thirty-eight days after tumor removal, visual function was maintained, and the papillary light reflex remained normal.
