Findings

No curated finding names inverse Marcus-Gunn phenomenon yet. Everything below is reference data from Mondo, HPO and GenCC, not evidence about what affects it.

Definition

Inverse Marcus-Gunn phenomenon is a rare congenital synkinesis where jaw opening by the pterygoid muscle (during eating or yawning) causes eyelid drooping from inhibition of the oculomotor nerve to the levator palpebrae superioris. Familial occurrence has been reported.
