What are the Symptoms of Marcus Gunn Jaw Winking Syndrome?
Parents typically notice the characteristic jaw-winking movements within the first few months of their childâs life. The most common symptoms include:
Involuntary upward movement of the upper eyelid when the child moves their jaw (e.g., during sucking, chewing, or talking). Ptosis (drooping of the upper eyelid) on the affected side, which can be constant or intermittent. Possible strabismus (misalignment of the eyes).
