RESUMEN
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.
