Ptosis (TOE-sis) refers to drooping of an upper eyelid of one or both eyes. The droop may be barely noticeable, or the lid can descend over the entire pupil. Ptosis can affect both children and adults, but usually occurs because of aging.
Ptosis Symptoms and Signs
The most obvious sign of ptosis is the drooping eyelid. Depending on how severely the lid droops, people with ptosis may have difficulty seeing. Sometimes people tilt their heads back to try to see under the lid or raise their eyebrows repeatedly to try to lift the eyelids.
The degree of droopiness varies from one person to the next. If you think you may have ptosis, compare a recent photo of your face with one from 10 or 20 years ago, and you'll likely see a difference in the eyelid skin.
Ptosis can look similar to dermatochalasis, a group of connective tissue diseases that cause skin to hang in folds. These diseases are associated with less-than-normal elastic tissue formation. Your eye doctor should be able to tell whether or not this is the cause of your drooping eyelids
