Congenital Eyelid Disorders
In distichiasis, an extra (partial or complete) row of eyelashes arises from or slightly posterior to the meibomian gland orifices (Fig 17-7). The abnormal eyelashes tend to be thinner, shorter, softer, and less pigmented than normal cilia and are therefore often well tolerated. Removal of the abnormal eyelashes with electrolysis or cryotherapy, or eyelid surgery, may be indicated if chronic corneal irritation is present.
