Abstract：
A 21-year-old, suspected female captive ferruginous hawk (Buteo regalis) was followed for 3 years due to an iridial mass of the left eye (OS) that progressively increased in size. Enucleation of OS was eventually recommended due to the iridial mass taking up approximately 75% of the anterior chamber, and the bird seemed less active. A complete physical examination, complete blood cell count, biochemistry, and survey radiographs were performed pre-surgery with no findings indicating metastasis. A subconjunctival enucleation was performed and the globe was submitted for histopathology through the Comparative Ocular Pathology Lab of Wisconsin. The histopathologic evaluation determined the mass to be consistent with an iris melanocytoma, which has not been previously reported in this species. The patient recovered well from surgery and has remained comfortable and active for 117 days post-surgery. This case report aimed to review the current available information on avian ocular neoplasms as well as describe the clinical presentation, medical management and surgical procedure, and long-term follow-up for this patient to enhance clinical understanding of the behavior of iris melanocytic tumors in avian species.
摘要：
一个21岁的年轻人,由于左眼的虹膜质量（OS）逐渐增加，可疑的雌性圈养铁质鹰（Buteoregalis）被随访了3年。由于虹膜质量占前房的大约75％，因此最终建议摘除OS。这只鸟似乎不太活跃。一个完整的体检,全血细胞计数,生物化学,术前进行了X线检查，没有发现表明转移。进行结膜下摘除术，并通过威斯康星州比较眼病理学实验室对眼球进行组织病理学检查。组织病理学评估确定肿块与虹膜黑色素细胞瘤一致，以前从未在该物种中报道过。患者从手术中恢复良好，并在手术后117天保持舒适和活跃。本病例报告旨在回顾鸟类眼部肿瘤的现有信息，并描述其临床表现。医疗管理和外科手术，并对该患者进行长期随访，以增强对禽类虹膜黑色素细胞肿瘤行为的临床认识。
