What Causes Ptosis?
Eyelid ptosis occurs when the muscle that usually raises the eyelid is not strong enough to do so. It can affect one eye or both eyes and is more common in the aging or elderly, as muscles in the eyelids may begin to deteriorate. One can, however, be born with ptosis, as it is hereditary. Ptosis may be caused by damage/trauma to the muscle which raises the eyelid, or damage to the nerve which controls this muscle. Such damage could be a sign or symptom of an underlying disease such as diabetes mellitus, a brain tumor, and diseases which may cause weakness in muscles or nerve damage, such as myasthenia gravis.
