Entropion is a common congenital disorder in lambs and is usually characterised by '''the turning in of one or both lower eyelids'''. In-turned hairs rub on the cornea and cause severe irritation. The condition is seen in most breeds of British sheep and is probably '''inherited''', although the nature of the inheritance is unknown. | Entropion is a common congenital disorder in lambs and is usually characterised by '''the turning in of one or both lower eyelids'''.
