Distichiasis

Distichia are hairs arising from a normally hairless eyelid margin. They may cause irritation resulting in ocular discharge or corneal ulcers. The factsheet describes the signs and treatment for this condition.

Ectopic cilia

Ectopic cilia are hairs which grow inappropriately on the inner surface of the eyelids. They may rub against the eye, causing a watery discharge and / or corneal ulcers. The signs and treatment are outlined in the factsheet.
