Augmented Surgery for Partially Accommodative Esotropia

ABSTRACT

The conventional surgery, based on the nonaccommodative angle after full correction of a hypermetropic refractive error, has resulted in a high incidence of undercorrection in the partially accommodative esotropia. In this study, we compared the conventional surgery group (82 patients)to the augmented surgery group (102 patients)in a total of 184 patients.The follow-up period in each group was at least 6 months. Of the 82 patients in conventional surgery group, 55 (67%)showed postoperative deviations of 10 delta or less, 25 (30%)undercorrection, and 2 (3%)overcorrection.Of the 102 patients in augmented surgery group, 81 (79%)revealed postoperative deviations of 10 delta or less, 9 (9%)undercorrection, and 12 (12%) overcorrection.The deviation was improved toward orthotropia by spectacle reduction of less than +2.0 D in overcorrected patients (2 of 2 in conventional surgery group, and 9 of 12 in augmented group).But 3 patients in augmented surgery group remained overcorrected. Our conclusion is that augmented surgery, even if it increase overcorrection, provides better postoperative alignment than conventional surgery in partially accommodative esotropia.
