Selective Surgery for Intermittent Exotropia Based on Distance/Near Differences

Selective surgery for intermittent exotropia based on distance/near differences.

BACKGROUND Classic teaching suggests that surgery for intermittent exotropia should be based on distance/near differences. Divergence excess, according to tradition, should be treated with symmetric lateral rectus recessions; simulated divergence excess and basic deviations should be treated with a recess/resect procedure. This teaching, to our knowledge, has not been systematically tested. O...

Consecutive esotropia following surgery for intermittent exotropia.

Improvement in distance stereoacuity following surgery for intermittent exotropia.

PURPOSE To evaluate whether distance stereoacuity improves following surgery for intermittent exotropia using the Frisby Davis Distance (FD2) and Distance Randot stereotests. METHODS Eighteen patients (median age, 24 years; range, 5 to 68 years) with intermittent exotropia were prospectively enrolled. Stereoacuity was measured pre- and 6 weeks postoperatively using the FD2 and Frisby near tes...

The distance angle to target in surgery for intermittent exotropia.

BACKGROUND Patients with intermittent exotropia may have an increase in their angle of strabismus in the distance when the angle is measured either after 1 hour of monocular occlusion or while the patients fixate on a distant target outdoors. The hypothesis that surgery should be performed for this larger deviation has been suggested but not tested. OBJECTIVES To test the hypothesis that surg...

Astigmatic Changes after Horizontal Rectus Muscle Surgery in Intermittent Exotropia

PURPOSE To evaluate the changes of refractive astigmatism after horizontal rectus muscle surgery in intermittent exotropic children. METHODS Sixty-nine exotropic patients were retrospectively reviewed. Of those, 35 patients received unilateral lateral rectus recession (BLR group, 35 eyes) and 34 patients received unilateral lateral rectus recession and medial rectus resection (R&R group, 34 e...
