Purpose To report the effect of asymmetrical bilateral lateral rectus recession combined with augmented partial vertical rectus transposition (VRT) in the management of exotropia, head turn, limited abduction, and anomalous vertical movements associated with unilateral exotropic Duane retraction syndrome (XT-DRS). Methods The medical records of all patients with unilateral XT-DRS associated with limitation of abduction who underwent surgery during a 5-year period from 2013 to 2018 with at least 6 months' follow-up were reviewed retrospectively. Outcome measures were changes in head turn, primary position distance and near exodeviation, degree of limited abduction, and anomalous vertical movements on adduction. Results A total of 11 patients (6 males) were included. Mean patient age was 16.3 years (range, 6-29). Exodeviation at distance and near fixation were corrected by means of 26.4Δ and 24.8Δ
