A case with a rare type of trigemino-oculomotor synkinesis: clinical and blink reflex study.

Several abnormal synkinetic eye movements during jaw movements may often be seen after trauma or congenitally in the Marcus Gunn jaw winking phenomenon. The most frequent type consists of unilateral ptosis and retraction of the ptotic lid upon moving the jaw. The authors describe a case with isolated simultaneous adduction of the left eye upon jaw movement. This paper presents a rare case of Marcus Gunn jaw winking with trigemino-oculomotor synkinesis.
