Extraocular muscle aplasia in Moebius syndrome.
A case of Moebius syndrome with bilateral aplasia of the medial and lateral recti is reported. The fibrous bands that replaced the medial recti were inserted posteriorly on the globe resulting in a restrictive large angle esotropia. Surgical intervention resulted in alignment in the primary position. The present case favors a primary mesodermal dysplasia of the extraocular musculature in Moebius syndrome.
