Marcus Gunn phenomenon associated with synkinetic oculopalpebral movements.

THE Marcus Gunn phenomenon is a well-known clinical entity wherein abnormal palpebral movements are associated with movements of the jaw. No record has been found in the literature of a case in which an associated concomitant convergent strabismus corrected itself automatically with the elevation of the ipsilateral ptotic lid when the jaw was opened or when ptosis was passively or surgically corrected. A case showing this congenital anomaly is described below.
