Modified Nishida's procedure combined with medial rectus recession in a case of Moebius syndrome

Moebius syndrome is a rare congenital disorder in which bilateral abduction is impaired, resulting in moderate- to large-angle esotropia. Various surgical procedures have been developed to correct esotropia in Moebius syndrome, including bilateral medial rectus (bimedial) recessions for moderate angles and bimedial recessions combined with vertical rectus transpositions or superior rectus transpositions for larger deviations. We describe a case of Moebius syndrome treated with modified Nishida's procedure and bimedial recession to correct large-angle esotropia.
