目的:描述一例马的脂肪肉芽肿性结膜炎。
方法:一位客户拥有的12岁Standardbredgelds,表现为慢性结膜炎和眼睑肿块。
方法:完整的眼科检查,手术切除,组织病理学,并对活检标本进行细菌培养。
结果:双眼上下眼睑受累,眼睑结膜上有多个黄色至白色结节,邻近眼睑边缘。结节的去除是通过部分tar板切除实现的。组织病理学检查显示肉芽肿性炎症和结膜固有层中假定的游离脂质的大液滴。该动物被诊断为脂肉芽肿性结膜炎。术后数月未观察到眼部不适;然而,三年后,发现了新的结膜结节,需要对三个眼睑进行第二次手术。第二次手术后2个月观察到左下睑暂时性内翻,随访18个月后无结膜结节复发。
结论:据我们所知,这是马的脂肪肉芽肿性结膜炎的首次报道。
OBJECTIVE: To describe a
case of lipogranulomatous conjunctivitis in a horse.
METHODS: A client-owned 12-year-old Standardbred gelding presenting with chronic conjunctivitis and palpebral masses.
METHODS: Complete ophthalmic examination, surgical excision, histopathology, and bacterial culture of biopsy samples were performed.
RESULTS: Upper and lower eyelids of both eyes were affected, with multiple yellow-to-white nodules on the palpebral conjunctiva, adjacent to the eyelid margin. Nodule removal was achieved via partial tarsal plate excision. Histopathological examination revealed granulomatous inflammation and large droplets of presumed free lipid in the conjunctival lamina propria. The animal was diagnosed with lipogranulomatous conjunctivitis. No postoperative ocular discomfort was observed for months; however, 3 years later, new conjunctival nodules were noticed, requiring a second surgical procedure on three of the eyelids. Transient entropion in the left lower eyelid was observed 2 months after the second surgery, and no recurrence of conjunctival nodules was observed after 18 months of follow-up.
CONCLUSIONS: To our knowledge, this is the first report of lipogranulomatous conjunctivitis in horses.
