Marcus Gunn jaw winking and Duane's retraction syndrome

Abstract

A three-month-old female presented with the unusual findings of Marcus Gunn Jaw Winking Phenomenon and Duane's Retraction Syndrome in the same eye. In considering suggested etiologies for these two disorders, a misdirection of peripheral innervation would account for both these entities co-existing. In reviewing the ophthalmic literature, the association of these disorders was first described around the turn of the century but much less in recent years.
