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
In this case the eyelid position is lower than normal. Eyelids can droop for many reasons, all fundamentally caused by a weakness of the muscles of the eyelid that open your eyes (levator muscle or Muellerâs muscle). Eyelids can also feel heavy if there is excess upper eyelid skin or eyebrow droopiness. These conditions can occur as you age and can be corrected with surgery. Dry eyes or eye allergies can also cause the eyelids to feel heavy. This may be treated with eye drops. Finally there is a condition called blepharospasm, in which there are uncontrollable spasms of the eyelids forcing intermittent eyelid closure. This condition may be treated with Botulinum toxin injections.
