Clinical analysis of surgical treatment for 21 cases with Duane's retraction syndrome

Abstract

Objective To investigate the characters of Duane's retraction syndrome (DRS) and the individualized surgical plan.Methods According to the character of DRS,we treated it with four methods:the medial rectus recession combined with ventrofixation,external rectus recession combined with ventrofixation,medial rectus and external rectus muscle simultaneously combined ventrofixation or external rectus muscle Y-shaped division.Results Upshoot and/or downshoot phenomenon and the head compensation position improved or cured postoperatively.Deviation angle of 12 patients was≤ 10△ in 14 patients with esotropia.Two cases appeared exotropia after medical rectus recession.Deviation angle of 6 cases of 7 patients with exotropia was ≤ 10△.In which five cases were performed external rectus muscle recession combined with ventrofixation; 2 cases were performed external rectus muscle Y shaped division.Conclusion Excluding the limiting factor,adequate recession of horizontal rectus could improve or remove the compensation head position.To help the patient with the head compensation position and strabismus ≤20△,we could give prismatic glasses.The curative effect is notable when the rectus Y shaped division with recession or both horizontal rectus recession simultaneously was done for upshoot or downshoot phenomenon.
