Lost muscle surgery

The authors present the results of transposition surgery without concomitant lateral rectus weakening in a retrospective review of five cases. Surgery was for large exotropia and marked limitation of adduction after surgical loss of the medial rectus muscle. Mean age...

Extraocular muscle OCT

The goal was to evaluate the use of the Heidelberg anterior segment optical coherence tomography (AS-OCT) to image extraocular rectus muscle insertions and to expand the use of the AS-OCT to also image vertical rectus muscles. The authors evaluated inter...

TED vertical strabismus surgery
