Unilateral Retraction the Umlateral Eyelid on Vomiting

I examined a patient who showed retraction of the right eyelid on vomiting. The right eyelid of the patient elevated concomitantly with the induction of gag reflex. She did not have ptosis. The levator function of the both eyes was normal. This case would be the first case report of glossopharyngeal-vagal-oculomoter synkinesis in the literature.
