To evaluate the outcomes of one muscle recession for horizontal comitant strabismus at a major referral hospital in the Middle East.
Retrospective charts review of postoperative outcomes of 90 patients who had undergone one muscle recession for small to moderate angle esotropia or exotropia. Data were collected for age, vision, amblyopia, previous surgery or botulinum toxin injection, preoperative deviation, amount and type of one muscle surgery, and postoperative deviation at the initial and last (six months or more) postoperative visit. Successful alignment was defined as ±10 prism diopters (PD) of orthophoria.
Sixty patients underwent medial rectus recession and 30 patients underwent lateral rectus recession. The average preoperative and last follow up deviation -respectively- was 24 ± 6.1 PD (15-35) PD and 14.62 ± 8.91 PD in the medial rectus recession group and 21.3 ± 5.1 PD (12-30) and 12.60 ± 8.74 in the lateral rectus recession group. The final success rates were 63.3% in both groups.
Single muscle strabismus surgery to correct horizontal strabismus had a variable outcome. Larger recession may help in achieving better outcomes. Properly designed prospective studies may help in identifying the factors affecting the outcomes of single muscle strabismus surgeries.
评估中东地区一家主要转诊医院针对水平共同性斜视进行单条肌肉后徙术的效果。
回顾性分析90例因小至中度内斜视或外斜视接受单条肌肉后徙术患者的术后结果。收集患者的年龄、视力、弱视情况、既往手术或肉毒杆菌毒素注射史、术前斜视度、单条肌肉手术的量和类型，以及术后首次和末次（术后6个月或更长时间）随访时的斜视度。成功矫正定义为正位视在±10棱镜度（PD）范围内。
60例患者接受了内直肌后徙术，30例患者接受了外直肌后徙术。内直肌后徙术组术前平均斜视度和末次随访时斜视度分别为24±6.1 PD（15 - 35）PD和14.62±8.91 PD，外直肌后徙术组分别为21.3±5.1 PD（12 - 30）和12.60±8.74 PD。两组最终成功率均为63.3%。
单条肌肉斜视手术矫正水平斜视的效果不一。更大程度的后徙可能有助于取得更好的效果。设计合理的前瞻性研究可能有助于确定影响单条肌肉斜视手术效果的因素。
