In general, if the ptosis is caused by a systemic muscle weakness, other muscles in the face, head, or body may be affected. A drooping eyelid can also be a symptom of a brain tumor or stroke, especially if it comes on within a few days or a few hours or if just one eye is involved.
Ptosis can be present at birth (congenital ptosis) or develop due to aging, injury or an aftereffect of cataract surgery or other corrective eye surgery. This condition also can be caused by a problem with the muscles lifting the eyelid, called levators. Sometimes a person's facial anatomy causes difficulties with the levator muscles. An eye tumor, neurological disorder or systemic disease like diabetes are other causes of drooping eyelids.
