Ptosis ( Drooping eyelid)
This refers to a droopy eyelid which may be one sided or both. The eye looks smaller and sometimes the person has a perpetually sleepy look. This patient is often born with ptosis, though the difference in the two eyelids becomes more apparent  when the child is 2-3 years old. Congenital Ptosis is correctable by surgery which is usually performed when the child is 4-5 years old.
