Abstract

PURPOSE: To investigate the types of strabismus surgeries performed and the reoperation rate in patients with Duane retraction syndrome (DRS).

DESIGN: Retrospective cohort analysis.

PARTICIPANTS: An insurance claims data set was used to identify patients diagnosed with DRS between 2007 and 2021.

METHODS: We recorded the type of strabismus surgery performed and the timing and frequency of reoperations. The hazard ratios (HRs) for reoperation were estimated according to the surgical methods using Cox regression analysis.

RESULTS: Of the 9435 patients diagnosed with DRS, 1023 (10.8%) underwent ≥ 1 strabismus operation. The median age at surgery was 5.0 years, and patients were followed for an average of 3.8 ± 3.0 years after their initial strabismus surgery. Most of the surgeries only involved horizontal muscle(s) (n = 734 [71.7%]). However, some patients underwent surgeries on vertical muscle(s) (n = 132 [12.9%]), vertical muscle(s) with transposition (n = 102 [10.0%]), and horizontal muscle with transposition (n = 51 [5.0%]). The estimated 5-year rate of reoperation was 18.2% (95% confidence interval [CI], 15.0%–22.2%). Compared with surgery on horizontal muscle(s) only, vertical muscle surgery (HR, 2.01; 95% CI, 1.30–3.11; P = 0.002) and vertical muscle surgery coupled with transposition (HR, 1.79; 95% CI, 1.06–3.02; P = 0.03) had an increased risk of reoperation.

CONCLUSIONS: Strabismus surgery on ≥ 1 horizontal muscles is the most common type of strabismus surgery performed on patients with DRS. Approximately 1 in 7 patients with DRS who had strabismus surgery underwent a reoperation. Patients who underwent vertical muscle surgery had a higher risk of undergoing a reoperation.
