Augmenting surgery for sensory esotropia with near/distance disparity with a medial rectus posterior fixation suture

Ten esotropic patients with near/distance disparity and diminished vision in one eye had monocular horizontal strabismus surgery combined with a posterior fixation suture placed on the medial rectus. Before surgery, all patients were at least 20 prism diopters (delta) more esotropic at near than at distance fixation. The disparity in the near/distance deviation was reduced by 18 delta.
