Abstract

Objectives: The goal of this study was to evaluate surgical techniques and outcomes in patients with Brown's syndrome.

Methods: A retrospective review was conducted of patients who underwent surgery of the superior oblique (SO) muscle between 2003 and 2011 at a referral center.

Results: In all, 190 patients (111 female and 79 male) with an age range of 4-50 years were included in the study. The right eye was affected in 98 patients, and the left eye in 92 patients. Abnormal head posture (AHP), ocular movement (OM), and hypotropia were assessed. The greatest improvement of AHP was seen following an SO temporal tenotomy (91%). Patients with a -4 limitation achieved full OM after a SO temporal tenotomy.

Conclusion: Temporal tenotomy provided the best improvement in limitation of elevation in adduction.
