Conjunctival foreign body (burdock pappus) induced keratitis in horses: 10 Cases

Abstract

Summary Ten cases of ulcerative or non-ulcerative keratitis due to frictional irritation from an eyelid or third eyelid foreign body were documented during a 2-year-period at the Veterinary Teaching Hospital. Cases were referred for corneal ulceration or ocular irritation of four days to three months duration. Following identification of the foreign body, treatment included removal with forceps or scarifying the conjunctival surfaces and supportive care. This report reviews epidemiologic, diagnostic, and therapeutic techniques that will benefit practitioners in the treatment of these cases.
