Abstract

  JWS is a syndrome which is characterized by synkinesis: that is when two or more than two muscles which have independent nerve supply, having simultaneous or coordinated movements. In 1883, Marcus Gunn had described a 15-year-old girl with a rare condition of a type of congenital ptosis that showed an associated motion of winking of the affected eyelid on the movement of the jaw. Hence this syndrome also termed as Marcus Gunn phenomenon or Marcus Gunn jaw winking syndrome. JWS is usually seen unilaterally, but can present bilaterally in rare cases [1-3]. The winking of eyelid may be elicited by opening the mouth, thrusting the jaw to the contralateral side, jaw protrusion, chewing, smiling, or sucking. This wink phenomenon is often discovered early, as the infant is bottle-feeding or breastfeeding.4,5Both the sexes are equally affected with no racial predilection. Incidence of this syndrome is approximately 5% amongst the population [1].
