Surgical Results of Duanes Retraction Syndrome

The authors reviewed medical records of 25 patients undergoing treatment for Duanes retraction syndrome. The patients were treated with appropriate horizontal muscle recession with or without posterior fixation suture, transposition procedures, and lateral rectus Y split and recession in order to relieve face turn, significant tropia in primary position, and upshoot or downshoot. The deviation in primary position was reduced by an average or 20.5 prism diopters; 19.5 prism diopters in horizontal muscle recession with or without posterior fixation suture, and 17.4 prism diopters in lateral rectus Y split and recession. The face turn was eliminated in 84%, while 100% in horizontal muscle recession with posterior fixation suture. The upshoot or downshoot was essentially corrected by lateral rectus Y split and recession(100%). Motility of the eye was not increased following each surgical procedures. According to the results, we could obtain appropriate deviation in primary position with each surgery postoperatively. Horizontal muscle recession with posterior fixation suture was effective in eliminating the face turn. Lateral rectus muscle Y-split and recession effectively corrected upshoot and downshoots.

Analysis of Abnormal Heal Posture and Surgical Results in the Patients with Duanes Retraction Syndrome

We evaluated retrospectively the clinical records of 46 cases of Duanes retraction syndrome. The purpose of this study is to demonstrate a clinical characteristics of this syndrome and improvement of abnormal head posture and degree of deviation in 14 cases undergoing operation. Unilateral manifestation was in 42 cases and 4 cases were involved bilaterally. Left eye was involved predominantly in 29 cases (63.0%). The frequencies analyzed according to Hubers classification were that Type I was 64.3%, Type II 7.1%, and Type III 28.6% in unilateral cases. Of unilateral cases, compensatory face turn was exhibited in 65.2% of Type I, 100% of Type II, and 60.0% of Type III. In primary position, 44.4% of Type I had esodeviation, and 100% of Type II ad 83.3% of type III had exodeviation. The major concerns of most patients or their parents were the correction of strabismus and gaze limitation, but they hardly recognized abnormal head posture. The correction of abnormal head posture and strabismus was achieved in 78.6% postoperatively.
