Abstract：
OBJECTIVE: To report the corneal clarity outcome following lamellar keratectomy of arcus lipoides corneae secondary to canine hypothyroidism and report a unique retinal manifestation of systemic disease.
METHODS: Four-year-old spayed female Sheepdog-Poodle canine.
METHODS: Lamellar keratectomy OD.
RESULTS: Bilateral severe arcus lipoides corneae was noted in the initial presentation. Bilateral, symmetric, and multifocal bullous retinal detachments were observed at subsequent visits. Biochemical testing revealed hyperlipidemia presumed to be associated with primary acquired thyroiditis. Corneal clarity and visual behaviors were significantly improved following unilateral lamellar keratectomy with no evidence of recurrence within the year following surgery. Bilateral retinal detachments and hyperlipidemia resolved months after initiation of thyroxine supplementation. Corneal lipidosis in the untreated eye remained static.
CONCLUSIONS: Lamellar keratectomy is a viable surgical option for the treatment of arcus lipoides corneae. Hypothyroidism should be considered a differential diagnosis for spontaneous, bilateral, multifocal, and serous retinal detachments.

摘要：
目的：报告犬甲状腺功能减退症继发角膜角膜脂类的板层角膜切除术后的角膜透明度结果，并报告一种独特的系统性疾病的视网膜表现。
方法：4岁的雌性牧羊犬-贵宾犬。
方法：板层角膜切除术OD。
结果：在最初的表现中注意到双侧严重的角膜骨脂。双边,对称，在随后的访问中观察到多灶性大疱性视网膜脱离。生化检测显示高血脂症推测与原发性获得性甲状腺炎有关。单侧板层角膜切除术后，角膜清晰度和视觉行为显着改善，手术后一年内无复发迹象。开始补充甲状腺素后数月，双侧视网膜脱离和高脂血症消退。未经治疗的眼睛中的角膜脂肪沉积保持静态。
结论：板层角膜切开术是治疗角膜角质骨的可行手术选择。甲状腺功能减退症应被视为自发性的鉴别诊断，双边,多焦点,和浆液性视网膜脱离.
