I'm Nikki 35yrs old. I was diagnosed with Marcus Gunn when I was a few months old. There were no surgeries in for it but in 1979 when i was 3 I was lucky enough to find an amazing surgeon at Johns Hopkins(Dr.Nicholas Iliff,check him out) who created a surgery called a Bi-lateral Sling to help correct(not cure) my condition . The sling helps with the drooping of the eye.
Its synkinesis of the III and V3 (third and fifth), not V3 and VII or III and VII.
III = levator palpebrae superioris
V3 = Pterygoid mm
Its other name is "Trigemino-oculomotor synkinesis"
Recall that the LPS elevates the eyelid. So when the mouth is opened, the LPS also contracts, raising the eyelid. The patient has ptosis at rest because there is no tonic innervation to the ipsilateral LPS to keep it open.
It is supposedly idiopathic, but it seems to me that it is likely due to mechanical compression of the facial nerve by the ramus of the mandible as the nerve is exiting through the stylomastoid foramen. This anatomical basis gives a plausible mechanism and would also explain why the majority of cases are sporadic. Anyone have thoughts on this??? Thanks for the vid... (I know by "third nerve" you meant V3 ;) ). Cheers!
Pretty striking example. For clarity, MGJW is a synkinesia of the pterygoid muscles and the ipsilateral orbicularis oculi muscle innervated by cranial nerves V3 (mandibular division of trigeminal nerve) and VII (Facial nerve). Activation of the medial pterygoid pulls the jaw to the contralateral side, stimulating (or disinhibiting) the ocular branch of CN VII. Lateral pterygoid pulls the jaw back and removes stimulation (or reinhibits).
Did you die???

Great comments! Yes third division of fifth cranial nerve and 7th nerve.
