Summary:ABSTRACT Objective To identify and examine factors that affect postoperative binocularity in children diagnosed with acquired nonaccommodative esotropia (ANAET). Design Retrospective chart review. Participants Thirty-four pediatric patients who received surgery for ANAET by 1 surgeon (I.M.) at the Ivey Eye Institute, University of Western Ontario (London, Ont.). Methods A multivariate logistic regression analysis was performed to evaluate the effect of the following factors on achieving stereopsis postoperatively: age at onset of esotropia (AO), duration of misalignment (DOM), presence of A/V pattern, recent intermittency of esotropia, and presence of dense amblyopia. Results Forty-one percent of all patients achieved stereoacuity of 100 seconds of arc or better. AO was found to be the only factor significantly associated with postoperative stereopsis (adjusted odds ratio = 1.063, P
