| Abstract |
|
Standard procedures for weakening the superior oblique muscle have been associated with significant complications in the treatment of superior oblique overaction and Brown's syndrome. Authors performed a technique for weakening the superior oblique muscle by lengthening the superior oblique tendon with silicone. Lengthening was accomplished by a nasal superior oblique tenotomy and inserting a segment of silicone 240 retinal band between the cut ends of the tendon. This technique was performed on 6 patients (8 eyes), 2 (4 eyes) with superior oblique overaction (SOOA), and 4 (4 eyes) with Brown's syndrome. Preoperatively patients with SOOA demonstrated A-patterns of 26 and 29 prism dioptersrespectively, and versions of +2 or +3 SOOA. Patients with Brown's syndrome demonstrated version of -3 or -4 elevation on adduction. Postoperatively, the A -patterns disappeared and SOOA was improved to 0 or +1, and underaction on adduction improved to 0 or -0.5 in Brown's syndrome. Based on these results, the superior oblique tenotomy with silicone expander is useful in patients with SOOA and Brown's syndrome. |
