Congenital ptosis, unilateral – http://id.who.int/icd/entity/1136579166

This is a congenital drooping or falling of the upper or lower eyelid. The drooping may be worse after being awake longer, when the individual's muscles are tired. This condition is sometimes called "lazy eye", but that term normally refers to amblyopia. If severe enough and left untreated, the drooping eyelid can cause other conditions, such as amblyopia or astigmatism. This diagnosis is occurring in one eye (unilateral).
