Abstract
A system and method of treating hyperactivity of an eyelid closing muscle in a subject includes providing a stimulation system in the subject with the hyperactivity of the eyelid closing muscle, sensing an activity of the eyelid closing muscle, and selectively stimulating eyelid opening muscle(s) or innervating nerves, eyelid opening reflexes, or eyelid opening reflexes in non-muscular tissue, using the stimulation system, without substantially activating the eyelid closing muscle. The system and method evokes eyelid movement in the subject.
