How might Marcus Gunn phenomenon be treated?

Treatment of Marcus Gunn phenomenon is not always needed because the condition tends to grow less noticeable with age.[1] Associated eye problems, such as horizontal strabismus, amblyopia, vertical strabismus, and double elevator palsy typically need to be addressed in affected individuals before considering how to manage the condition itself.[2] These related eye problems may be corrected with eyeglasses, surgery, and/or medications.[1]

Surgery for Marcus Gunn phenomenon may be considered for ptosis and jaw winking that are considered cosmetically significant, or causing amblyopia. Depending on the degree of ptosis and severity of jaw winking, several surgical techniques have been proposed.[2] For mild Marcus Gunn phenomenon, management has included observation, levator muscle resection, and the Fasanella-Servat procedure.[2]
