Plain-English summary
An African grey parrot was brought to the vet because it had a bulging left eye and a noticeable lump near the eye. After tests showed the lump was a cystic mass and not infected, the vet suspected it was caused by a lack of vitamin A and started vitamin supplements. However, since the lump didn't improve, the vet decided to surgically remove it. The surgery was successful, and the parrot healed well without any signs of the lump returning after 10 months.

Abstract
An African grey parrot (Psittacus erithacus) was presented with exophthalmos and a semisolid mass dorsomedial to the left eye that led to ventrotemporal deviation of the globe. Ultrasonography of the eye revealed a well-demarcated mass of cystic appearance, retrobulbar to the left eye. Cultures of samples of the mass acquired by fine needle aspiration were negative for bacteria and Mycoplasma species. Metaplasia of a periorbital gland caused by hypovitaminosis A was suspected, and vitamin A supplementation was initiated. Because of unresponsiveness to therapy, the cystic mass was surgically removed. The histologic diagnosis was adenoma. The surgical wound healed well, and no recurrence was observed 10 months later. To our knowledge, this is the first report of surgical removal of a retrobulbar adenoma in this species with the eye remaining intact and functional.
