Strabismus Surgery: Surgical correction of ocular deviation.

Conservative Treatment or Observation: Non-surgical management, including clinical observation for natural history, prism therapy, or orthoptic treatment.

Study summary

This retrospective study constructs the largest multicenter registry of strabismus care in Japan. The registry evaluates real-world surgical and conservative treatment outcomes, safety, and natural history for various types of strabismus, including common, rare, and complex cases.

Inclusion Criteria: * Patients diagnosed with strabismus who underwent clinical evaluation or management (including observation for natural history, conservative treatment, or surgery) at participating institutions. * Observation period for common strabismus: A restricted recent timeframe (e.g., the most recent 3 years) to minimize selection bias. * Observation period for rare and complex strabismus: Up to 10 years (January 1, 2016, to the date of Institutional Review Board approval) to secure an adequate sample size. Exclusion Criteria: * Patients who formally opted out of data utilization for this study.

Primary outcome measure(s)

  • Success rate of ocular deviation correction and residual deviation angle — At standard observation intervals (2 to 4 weeks, 3 to 6 months, 1 year, and 2 years post-treatment or baseline) and through study completion, up to 10 years.
    Assess the angle of ocular deviation and determine the success rate of clinical management (including observation for natural history, surgical, or conservative treatments) based on established clinical criteria.
