Ptosis repair surgery corrects the drooping of the upper eyelid known as ptosis (pronounced “toe-sis,” short for blepharoptosis) by repositioning the underlying muscles to lift the upper eyelid.The droop may be barely noticeable or the eyelid can sag to such an extent that it covers your pupil, the black dot in your eye. Ptosis surgery is most often performed by oculoplastic surgeons and ophthalmologists who specialize in eyelid surgery.
Ptosis repair may be done on its own, or at the same time as an upper eyelid blepharoplasty, which involves removing excess skin and fat, according to Dr. Katherine Zamecki, a board-certified oculoplastic surgeon in Danbury, Connecticut. “Ptosis repair surgery can involve an incision in the skin in the crease of the upper eyelid, or it can sometimes be done from the underside of the eyelid,” Dr. Zamecki explains. “Your surgeon will discuss with you which is the preferred technique in your particular case.” Â
Upper eyelid ptosis is most common in older adults, who may notice over time that they’re losing peripheral vision or looking through their eyelashes. “Looking down, as is done during reading, can cause the eyelid to droop even more, causing further difficulty with the vision,” explains Dr. Zamecki.Â
Ptosis can have a range of causes:Â
- The tendon (aponeurosis) belonging to the main muscle responsible for lifting the upper lid—the levator muscle—stretches and weakens with age. This causes the tissues within the eyelid to stretch, leading to a drooping eyelid. “This is the most common type of ptosis, commonly referred to as aponeurotic or acquired ptosis,” says Dr. Zamecki.
- Some people are born with congenital ptosis, which can lead to amblyopia (the medical term for the permanent reduction in vision some people refer to as a “lazy eye”). The levator muscle typically does not work well in these cases, notes Dr. Zamecki.
- Trauma can stretch the eyelid muscle and cause acquired ptosis. In fact, even devices used to hold the eye open during LASIK or cataract surgery can lead to this problem.Â
- The condition can also result from underlying medical conditions that affect muscle functioning, such as myasthenia gravis or a tumor. Your doctor should investigate this possibility before surgery.
