What is ptosis?

“Ptosis” means drooping. When the upper eyelid droops, it is called blepharoptosis, or upper eyelid ptosis.

Why do people get ptosis?

There are several reasons an eyelid might droop. Some babies are born with ptosis in one or both eyelids. These children must have a thorough eyelid examination.

Ptosis can occur later in life if the muscles or ligaments that normally raise the eyelid are weakened by injury or disease. Sometimes the drooping is a result of damage to the nerves that control the eyelid muscles.

Most ptosis just happens with aging. As a person ages, the skin and muscles of the eyelids stretch and weaken. Sometimes, previous eye surgery speeds up this change because the instruments used to keep the eye open during surgery can stretch the eyelid.
