Ptosis is the medical term for droopy eyelids. The edge of the eyelid falls and covers the pupil causing a falsely tired appearance. The vision may be blocked. Ptosis occurs in adults as the tendon that lifts the eyelid stretches or separates from its normal attachment. Children can be born with ptosis due to poor development of the eyelid’s elevating muscle. It can also occur after cataract or retinal surgery. Adult ptosis can sometimes be improved with topical medication.Ptosis is corrected with surgery.
