Plain-English summary
A 19-year-old female Congo African grey parrot was brought in because she had a solid, pigmented mass in her left eye that was affecting her vision. After a biopsy confirmed it was a type of tumor called an iridociliary adenoma, the veterinarian decided to remove the eye to prevent further issues and to make the parrot more comfortable. The surgery was successful, and these types of tumors are usually benign, meaning they typically don't come back after being completely removed.

Abstract
A 19-year-old female Congo African grey parrot () presented for an oval, solid, pigmented, suspected intraocular mass with extrascleral extension through the inferior cornea of the left eye. The eye was nonvisual, and intraocular portions of the mass significantly altered the posterior chamber. Neoplasia was confirmed by biopsy, and enucleation was performed because of the severity of ocular disease, loss of vision, enhancement of patient comfort, and potential metastasis. Histopathologic examination of the entire globe revealed a pigmented iridociliary adenoma. Iridociliary adenomas have been rarely reported in birds, and this case report details diagnosis and treatment. Iridociliary adenomas in other species are often benign, indicating this neoplasia can be successfully treated with no reoccurrence by complete excision.
