Treatment of Duane's retraction syndrome by recession of medial and lateral rectus muscles combined with Y-splitting procedure

Abstract

To investigate the new surgical method and effect of treatment of Duane's retraction syndrome by recession of medial and lateral rectus muscles combined with Y-splitting procedure. Eight patients with Duane retraction syndrome underwent surgery. Among seven cases of normal direction Duane's retraction syndrome, Six patients were performed recession of medial and lateral rectus muscles with Y-splitting of lateral rectus muscle, one patient was performed recession and Y-splitting of lateral rectus muscle. One patient with inverse Duane's retraction syndrome was performed bilateral recession of medial and lateral rectus muscles combined with Y-splitting of both medial rectus muscles. All patients were followed up 1 to 12 months. Ocular alignment, ocular motility and change of compensatory head posture were evaluated. The compensatory head posture, upshoot or downshoot were eliminated. Globe retraction and narrowing of palpebral fissure got improved. Postoperative ocular alignment of 6 cases achieved orthophoria, with 2 cases of residual strabismus. Recession of medial and lateral rectus muscles combined with Y-splitting procedure is an effective method for treatment of Duane's retraction syndrome, aiming at correction of ocular deviation and head posture and elimination of globe retraction.
