Abstract
Marcus Gunn Jaw Winking Synkinedis (MGJWS) is caused by aberrant innervation of the levator palpebrae superioris muscle by a branch of the trigeminal nerve’s motor division that supplies mastication. This phenomenon is seen in 4 to 6% of congenital ptosis patients. MGJWS mostly occurs i an unilateral and isolated manner but it is less frequently bilateral and associated with ocular and systemic abnormalities. Here we describe two cases of children who presented with ptosis and were diagnosed with MGJWS
