A dermoid (also sometimes referred to as a “choristoma”) represents an area of normal haired skin in an abnormal location on the eye or adnexal tissue. Lesions may affect the cornea &/or adjacent structures including the limbus, conjunctival surfaces, third eyelid and/or eyelid. Changes are congenital so are typically noted soon after the eyes open at 2 weeks of age. Secondary conjunctivitis and discomfort may manifest as blepharospasm &/or ocular discharge. Commonly affected breeds include the German Shepherd, the Dachshund & the St Bernard.
