Tip 1 Duane Retraksiyon Sendromlu Hastalarda Cerrahi Sonuçlar

Purpose: To assess the results of surgery techniques used in Duane’s retraction syndrome (DRS) type 1.\udMaterial and Method: 194 DRS cases followed in the department of strabismus were retrospectively investigated. We\udassessed 58 cases operated for esotropic DRS type 1 in terms of pre- and post-operative deviations in primary position,\udabnormal head posture (AHP), abduction deficiency, globe retraction, and up-down shoot. The cases were divided into\ud3 groups according to the surgical technique applied. The mean follow-up period was 22.4±4.6 (1-13 years) months.\udResults: The cases in group 1 had undergone uni- or bilateral medial rectus (MR) recession, and the postoperative 1stmonth\udimprovement rates for distance deviation, near deviation and AHP were 68.6%, 73.9% and 50%, respectively.\udThese rates were 69.3%, 64.7% and 57.1%, respectively in group 2 which consisted of eyes that had undergone vertical\udrectus muscle transposition (VRT) surgery. In group 3, in which we had performed Y-split (with or without LR/MR\udrecession) surgery, the improvement rates for distance and near deviation were 63.6% and 63.9%, and 50% was determined\udfor AHP. The improvement in globe retraction was 60% in group 1 and 66.6% in group 3.\udDiscussion: Medial rectus muscle recession was more effective for correction of deviation and AHP in cases of DRS type 1. VRT\udwas found to be more effective surgical option in abduction deficiency. Y-split surgery has an important place in eliminating\udglobe retraction and up/down shoot.
