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
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. Recommended For You.
