01 disorders of lashes
This document summarizes various disorders of the eyelashes including: 1. Trichiasis, where eyelashes grow backwards and rub against the eye, potentially causing corneal damage. 2. Metaplastic lashes which arise abnormally from meibomian gland openings due to conditions like cicatrizing conjunctivitis. 3. Distichiasis which is a second row of eyelashes growing from meibomian gland openings and can be treated with cryotherapy or surgery.
