Brown syndrome associated with Marcus-Gunn jaw winking ptosis

Abstract

Brown syndrome is a rare mechanical disorder characterized by restriction of the superior oblique trochlea-tendon complex.  Marcus-Gunn jaw winking ptosis is a more common congenital oculofacial synkinesis in which blepharoptosis is associated with upper eyelid contraction that accompanies jaw movement.  In this report, we present the case of a 50-year-old woman with unilateral Brown syndrome and Marcus-Gunn jaw winking ptosis in the fellow eye.
