Effect of preoperative stability of alignment on outcome of strabismus surgery for infantile esotropia.

Introduction: Some strabismus surgeons wait until the angle of deviation stabilizes prior to operating on patients with infantile esotropia. This study evaluated whether a preoperative increase in the angle of deviation affected surgical outcomes.

Methods: This was a retrospective comparative case series in which records of patients with infantile esotropia, who had surgery performed before age 2 years and who were followed for at least 2 years postoperatively, were reviewed to identify two groups for comparison: the first had /=10(Delta) increase in the angle of deviation prior to surgery.
