Ptosis is a condition which may be congenital, i.e: by birth or it may develop in a later stage of life, even in our old age. The eyelids are elevated by the contraction of the levator palpebrae superioris muscle. Congenital ptosis is because of localized myogenic dysgenesis. Instead of normal muscle fibres, fibrous and adipose tissues are present in the muscle belly, diminishing the ability of the levator to contract and relax normally. The ptosis can also occur when the innervation to the levator is interrupted through neurologic or neuromuscular junction dysfunctions.
