Recurrent corneal ulceration in a young dog due to an ectopic cilium in an unusual location

This is a report of an 11-month-old dog with recurrent corneal ulceration over the preceding three months. The cause was confirmed to be a single ectopic cilium in a rare location—the lower eyelid palpebral conjunctiva. Surgical excision of the aberrant hair was required for resolution of the disease process. This report demonstrates the importance of a systematic clinical approach to corneal ulceration in dogs, highlighting the importance of a complete history and ophthalmic examination. In non-healing or recurrent corneal ulceration in young dogs, exploration for ectopic cilia is important. Magnification and a good light source are essential in such cases. Surgical excision is curative and the prognosis is good.
