There are several reasons an eyelid might droop. Some babies are born with drooping eyelids - also known as ptosis - in one or both eyelids. Pediatric ptosis requires a detailed eyelid examination and treatment generally depends on the function of the eyelid muscles. 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 hastens this change because the instruments used to keep the eye open during surgery can stretch the eyelid a bit.
How is ptosis treated?
If the ptosis does not reduce vision and the patient does not mind the appearance, the doctor might recommend no treatment at all.
If the ptosis causes a problem with vision, appearance, or both, treatment may be indicated. The treatment used depends on whether the ptosis is caused by a disease process or by aging changes. Treating ptosis caused by aging changes typically involves surgery.
