Marcus Gunn Jaw-Winking synkinesis in a neonate

Abstract

This report describes a 9-day-old female infant admitted for hypocalcemic seizures. The hypocalcemia was treated, but the infant was noted to have vesico-ureteral reflux and a mild ptosis of her left eye with rhythmic blinking during bottle feeding. The eye findings were subsequently diagnosed as Marcus Gunn jaw-winking Synkinesis.
