Purpose: To compare postoperative outcomes according to surgical method in partially accommodative esotropia in patients over 4 years of age. Methods: We compared motor and sensory outcomes between conventional and augmented surgery in 66 patients. The postoperative follow-up period was at least 24 months. The formula for the amount of the rectus muscle recession was based on the distant angle deviation after hyperopic correction in the conventional group and the average amounts of the distant angle deviation with and without full correction of hyperopia in the augmented group. In addition, the conventional group was divided into 2 sub-groups to compare surgical outcomes. The A group consisted of patients who underwent surgery with the amount of surgical correction based on distant angle deviation after full hyperopic correction. The B group consisted of patients under the same condition after reduced hyperopic correction to achieve best corrected visual acuity (BCVA). Results: Among the patients who had an ocular alignment less than 10 PD, orthophoria was significantly higher in the conventional group than in the augmented group on the last follow-up. When comparing the 2 conventional sub-groups, the postoperative stereoacuity was better in group B than in group A. Among patients with a postoperative overcorrected alignment of more than 10 PD who underwent augmented surgery, 75% showed decreased postoperative stereoacuity compared to preoperative stereoacuity. Conclusions: In partially accommodative esotropia in patients over 4 years of age, conventional surgery compared to augmented surgery after reduced hyperopic correction is better in order to achieve BCVA for postoperative stereoacuity as well as ocular alignment.
