causes droopy eyelids
Droopy eyelids can also be caused by trauma, surgery, or by damage to the muscles that raise the eyelids or to the nerves that control these muscles. Tumors, neurological disorders, systemic diseases, and certain drugs have also been known to cause ptosis. Depending on the cause, ptosis may be classified as: Neurogenic ptosis: Refers to the condition in which the nerves attached to the muscle are affected; Myogenic ptosis: Refers to sagging of the lid due to a problem with the muscle that raises the eyelid; Aponeurotic ptosis: Refers to the stretching and weakening of the tendon responsible for raising the eyelid
