Abstract

Purpose: To determine success rates over time for strabismus surgery for sensory exotropia and to determine factors associated with successful outcomes. Methods: We retrospectively reviewed medical records of patients with sensory exotropia (best-corrected visual acuity ≤20/200 in the affected eye) who underwent strabismus surgery between May 2009 and December 2019. Patients with paralytic/restrictive exotropia and patients who did not follow up postoperatively were excluded. Surgical success was defined as exotropia of ≤10Δ or esotropia of ≤6Δ. Cox-proportional hazard models were used to evaluate covariate relationships with surgical outcome (α = 0.05). Results: A total of 94 patients (64% female) were included. Mean patient age was 27.2 years (range, 3-69). Mean follow-up was 2.35 ± 2.77 years. The mean preoperative near deviation was 39Δ ± 14.8Δ of manifest or intermittent exotropia. Successful alignment was achieved in 51 of 83 patients (61%) at 1 month, 19 of 32 (59%) at 1 year, and 8 of 16 (50%) at 5 years. We found a significant correlation (P value = 0.0476) between success and smaller surgical doses in patients that underwent one- and two-muscle surgeries. Conclusions: In our study cohort of 94 patients, 50% of patients still had satisfactory ocular alignment at 5 years.
