Plain-English summary
A 12-year-old Standardbred gelding was diagnosed with a condition called lipogranulomatous conjunctivitis, which is a type of eye inflammation. The horse had been experiencing chronic eye irritation and had developed several yellow-to-white lumps on the inside of its eyelids. After a thorough eye exam and surgery to remove the lumps, the tissue was examined and showed signs of inflammation and fat deposits. Although the horse did not have any eye discomfort for several months after the first surgery, new lumps appeared three years later, leading to a second surgery on three eyelids. After the second surgery, there was a temporary issue with the eyelid turning inward, but no new lumps were found during the 18 months following that procedure. Overall, the treatment was effective, as there were no further issues with the conjunctival nodules after the second surgery.
Abstract
OBJECTIVE: To describe a case of lipogranulomatous conjunctivitis in a horse. ANIMAL STUDIED: 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. CONCLUSION: To our knowledge, this is the first report of lipogranulomatous conjunctivitis in horses.
