Marcus Gunn Jaw-Winking Syndrome

Vijayalakshmi A. Senthilkumar et al.

Excerpt

Marcus Gunn jaw-winking syndrome (MGJWS) is noted in congenital blepharoptosis. MGJWS was first described by a Scottish ophthalmologist Dr.Robert Marcus Gunn in the year 1883. This syndrome was initially reported in a 15-year-old girl as unilateral ptosis associated with the upper eyelid contraction on the same side. Other names of MGJWS include Marcus-Gunn jaw winking phenomenon (MGP), Marcus Gunn ptosis, Marcus Gunn jaw winking trigemino-oculomotor synkinesis, Maxillopalpebral synkinesis, and Pterygoid-levator synkinesis. It is one of the congenital cranial dysinnervation disorders (CCDD), and these individuals have variable degrees of blepharoptosis in the resting, primary position. It is associated with synkinetic movements of the upper eyelid during masticating movements of the jaw. It is usually unilateral but may present bilaterally also.
