Note
A rare condition of unknown etiology that is characterized by movement of the upper eyelid in a rapid rising motion (a "wink") each time the jaw moves. This phenomenon may be elicited by opening the mouth, thrusting the jaw to the side, jaw protrusion, chewing, smiling, or sucking. It is usually present at birth and may occur with other eye abnormalities (such as STRABISMUS) or vision problems. It is usually unilateral but can affect both eyes in rare cases. It is generally sporadic, but familial cases with autosomal dominant inheritance have been reported. OMIM: 154600
