Distichiasis in Dogs
Distichiasis is when an eyelash arises from an abnormal spot on the eyelid. The mutation affects both dogs and humans. Distichiae usually exit from the duct of the meibomian gland at the eyelid margin.
They are usually multiple and sometimes more than one arises from a duct. They can affect either the upper or lower eyelid and are usually bilateral. The lower eyelids of dogs usually have no eyelashes. Distichia usually cause no symptoms because the lashes are soft, but they can irritate the eye and cause tearing, squinting, inflammation, and corneal ulcers and scarring.
Treatment options include manual removal, electrolysis, electrocautery, cryotherapy and surgery to remove the growth.
