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.
Claims8
A stimulation system for treating hyperactivity of an eyelid closing muscle in a subject, the system comprising:
- an activating switch configured to generate a first signal;
- a processor, in communication with the activating switch, configured to generate at least one stimulation parameter, based on the first signal, in order to stimulate one or more eyelid opening muscles or innervating nerves of the subject;
- and
- a stimulator configured to receive the at least one stimulation parameter and to selectively activate the one or more eyelid opening muscles or innervating nerves of the subject based on the at least one stimulation parameter, without activating the eyelid closing muscle in the subject.
