The authors report an unusual case of Marcus Gunn syndrome in an adult patient, characterized by classical Marcus Gunn on one side and inverse Marcus Gunn on the other side. The patient exhibited a “see-saw” kind of eyelid movement on opening and closing the mouth and on moving the jaw from side to side. This clinical entity has been reported very rarely. A similar but etiologically different acquired condition seen commonly in adults, Marin Amat syndrome, is also discussed.
