Purpose
The purpose of this study was to determine the effect of unilateral large lateral
rectus (LR) recession on head turn and horizontal ocular deviation in patients with
unilateral exotropic Duane retraction syndrome.
Patients and methods
This was a prospective, interventional study of 10 consecutive patients with
unilateral exotropic Duane retraction syndrome associated with contralateral
head turn. All patients underwent large (8.5–10 mm) unilateral LR recession on
the affected eye. All patients were followed up for at least 6 months. Preoperative
and postoperative ocular deviation, angle of head turn, stereoacuity, and severity of
limitation in abduction and adduction were recorded and analyzed.
Results
Mean head turn decreased from 30.5±9.56° (range, 15°–40°) to 6.5±4.74° (range,
0°–15°) (P |
