Congenital Ptosis/Ptosis Repair
Ptosis is when the lid margin itself is low which leads to an obstruction in field of vision. If you have ptosis, it is common to have compensatory use of the forehead and brow muscles in an attempt to elevate the eyelid to see better. Symptoms are often worse at the end of the day and when tired. There are two muscles in the eyelid that control lid height – the levator muscle and Mueller’s muscle. Surgery involving the levator muscle is performed by making a lid crease incision on the outside of the eyelid whereas ptosis correction by repair of Muellers muscle is performed internally thereby avoiding a skin incision. Correction of ptosis can be a dramatic improvement in vision and appearance in allowing the person to appear more alert and awake.
Children may be born with droopy eyelids and this is called congenital ptosis. The cause of this is different than in an adult (which is usually due to wear and tear with age). In patients with congenital ptosis, there is an abnormality of the muscle itself and it does not function normally. Repair is dictated by the degree of function of the muscle. This can be challenging to correct and is a surgery that is usually performed only by oculoplastic and pediatric ophthalmologists.
