OBJECTIVE: The aim of this study was to describe the clinical features and surgical outcomes of teenage and adult patients with esotropia undergoing strabismus surgery with adjustable sutures.
METHODS: Seventy-three patients were included in this retrospective, cohort study. Patients were stratified into group 1 (35 with childhood-onset esotropia [CET]) and group 2 (38 with adult-onset esophoria-tropia [EPT]). Preoperative immediate, 2-week, and 4-6-month postoperative measurements of ocular alignment, as well as fusional testing, were performed. Postoperative success was defined as distant (6 m) and near (33 cm) alignment within 12 prism diopters (PDs) of orthotropia in the primary position at 2 weeks and at 4-6 months with a single surgery.
RESULTS: Patients with CET more frequently had hyperopia and amblyopia and were more likely to present for surgery because of psychosocial strabismus-related problems. Patients with EPT predominantly had myopia and were more likely to experience diplopia and asthenopia. In group 1, the mean preoperative distance deviation improved from 30 PDs to 4 PDs at 2 weeks and to 4 PDs at 4-6 months (p < 0.001). In group 2, mean preoperative distance alignment improved from 22 to 3 PDs at 2 weeks and to 3 PDs at 4-6 months (p < 0.001). The mean objective, single-surgery success rate at 2 weeks was 88% and 97% in groups 1 and 2, respectively. At 4-6 months, postoperative success was 71% in group 1 and 80% in group 2. The majority of patients reported subjective improvement.
CONCLUSIONS: There are distinct preoperative differences between CET and EPT patients. Adjustable, strabismus surgery in this cohort is safe and effective in achieving subjective and objective success.
