Study group discussion: Marcus gunn jaw winking syndrome and Ptosis

Interesting one - congenital ptosis associated with winking motion of the affected eyelid on the movement of the jaw. Known as Marcus gunn jaw winking syndrome.

On opening, side ward movements of jaw, increase of palpebral aperture!

Usually jaw movement to opposite side! Jaw winking.

What are the causes of Ptosis?

Neurologic causes of Ptosis include Horner's syndrome, in which the pupil is constricted, and third nerve palsy, in which there are abnormalities of eye movements and the pupil may be dilated. Local causes include congenital and acquired disorders of the levator muscle complex and tumors and infections of the eyelid. Myasthenia should always be considered.
