title: Bilateral Marcus Gunn jaw winking synkinesis with monocular elevation deficiency: a case report and literature review.
abstract: Marcus Gunn jaw winking synkinesis (MGJWS) occurs due to an aberrant innervation of the levator palpebrae superioris muscle by a branch of the motor division of the trigeminal nerve that supplies the muscles of mastication. MGJWS is mostly unilateral occurring in isolation and is less frequently associated with ocular or systemic abnormalities. Although MGJWS is mostly unilateral, few bilateral cases have been reported. Here we describe a rare case of bilateral MGJWS in an 18 year-old male patient with asymmetric bilateral ptosis and monocular elevation deficiency in the right eye.
