A distichia is an eyelash that arises from an abnormal spot on the eyelid. This abnormality, attributed to a genetic mutation, is known to affect dogs and humans. Distichiae (the abnormal eyelash) 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. Distichiae 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. ==Commonly affected breeds== In veterinary medicine, some canine breeds are affected by distichiasis more frequently than others: *Cocker Spaniel *Dachshund (especially the miniature longhaired Dachshund) *Bulldog *Pekingese *Yorkshire Terrier *Flat-Coated Retriever *Shetland Sheepdog *Poodle *Elo (dog) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Distichia」の詳細全文を読む スポンサード リンク
