Distichiasis
As distichiasis (v. Greek .: δι- = two, στίχος = row, line) is called a disease of the eye in humans or animals, in which fine, lash-like hairs from the sebaceous glands (more precisely the Meibomian glands ) of the lid margin out towards of the eyeball grow, causing trichiasis (also as a result of eyelid inflammation ) , i.e. H. irritation and damage to the cornea can occur. The hairs are called distichia and usually grow out of the gland openings. So they form a kind of second row of eyelashes.
The disease can affect both the upper and lower eyelids and can affect one or both eyes. If the symptoms are more severe, the hairs causing them can be surgically removed.
