ABSTRACT

Aim:To evaluate the surgical outcomes of augmented medial rectus recession with non-absorbable 5.0 white braided polyester suture (Alcon Laboratories, Forth Worth, Texas, USA) loops in patients diagnosed with convergence excess esotropia. Methods: Clinical records of 21 patients with convergence excess esotropia who have been operated with symmetric medial rectus recessions augmented with non-absorbable suture loops were reviewed. Initial scleral bite was planned according to the distance deviation. Non-absorbable sutures tied leaving a loose loop which was 1 mm for a near–distance disparity of 10 PD, 1.5 mm for 15PD, and 2 mm for 20 PD. Postoperative changes in near-distance disparity were evaluated. Results: The mean preoperative near-distance disparity of 17,21 ± 1,68 standard mean of error (SE) prism diopters (PD) decreased to 3,15 ± 0,88 PD SE at 12 month postoperatively. Near-distance disparity of 10 PD or less was achieved in all patients after surgery at the sixth month, 1 patient showed 12 PD of disparity at the first-year control. No overcorrection has been noted. Conclusion: Bilateral medial rectus muscle recession procedure augmented with polyester suture loops effectively decreases the disparity between near and distance deviations in patients with convergence excess esotropia. Because of our good results and an easy, noninvasive approach without any additional complications, we recommend this technique to treat convergence excess esotropia

摘要

目的：评估用不可吸收的 5.0 白色编织聚酯缝合线（Alcon Laboratories，Forth Worth，Texas，USA）环增强内直肌后缩对被诊断为会聚过度内斜视的患者的手术效果。方法：回顾了 21 例接受过对称内直肌退缩手术并采用不可吸收缝线环增强的会聚性过度内斜视患者的临床记录。根据距离偏差计划最初的巩膜咬合。不可吸收缝线系好后留下一个松散的环，10 PD 的近距差异为 1 毫米，15 PD 为 1.5 毫米，20 PD 为 2 毫米。评估了近距离视差的术后变化。结果：平均术前近距离视差为 17,21 ± 1,68 标准平均误差 (SE) 棱镜屈光度 (PD) 降至 3,15 ± 0，术后 12 个月时 88 PD SE。所有患者在术后第 6 个月均达到 10 PD 或更少的近距差异，1 名患者在第一年对照时显示 12 PD 差异。没有注意到过度校正。结论：双侧内直肌回缩术联合聚酯缝线环可有效降低收敛性过度内斜视患者近距和远距偏差的差异。由于我们的良好结果和简单、无创的方法，没有任何额外的并发症，我们推荐这种技术来治疗会聚过度内斜视 结论：双侧内直肌回缩术联合聚酯缝线环可有效降低收敛性过度内斜视患者近距和远距偏差的差异。由于我们的良好结果和简单、无创的方法，没有任何额外的并发症，我们推荐这种技术来治疗会聚过度内斜视 结论：双侧内直肌回缩术联合聚酯缝线环可有效降低收敛性过度内斜视患者近距和远距偏差的差异。由于我们的良好结果和简单、无创的方法，没有任何额外的并发症，我们推荐这种技术来治疗会聚过度内斜视
