Surgical outcome of patients with unilateral exotropic Duane retraction syndrome

Abstract Purpose To describe the clinical features and surgical outcomes of patients with unilateral exotropic Duane retraction syndrome (DRS). Methods The medical records of patients with unilateral exotropic DRS who underwent surgery between March 2015 and February 2018 were reviewed retrospectively. Results A total of 40 patients (mean age, 18.75 ± 12.54 years; 21 males [53%]) were included. In 28 patients (70%) the left eye was involved. All patients had globe retraction and head turn toward the opposite side of the affected eye. Remarkable upshoot/downshoot movement was detectable in 11 patients (28%). The mean deviation for near and distance improved from 24.37Δ ± 12.34Δ (range, 6Δ-77Δ) and 19.67 ± 10.76Δ (range, 4Δ-60Δ) to 4.25Δ ± 8.61Δ (range, 0Δ-50Δ) and 2.62Δ ± 6.15Δ (range, 0Δ-35Δ) after the first surgery (P Conclusions Simple lateral rectus recession (with or without Y-splitting), even in the presence of significant deviation (through 35Δ), seems to be a successful procedure for management of patients with unilateral exotropic DRS.
