In a clinical study the authors evaluate efficiency of the operation on oculomotoric muscles by the hang-back retroposition method. A total of 70 children have been operated on, 52 of the patients suffering from esotropia and 18 from exotropia. The mean preoperation deviation in esotropia was 30 +/- 12 pdpt, the postoperation deviation was in the range of 6 +/- 7 pdpt. In the exotropia cases the preoperation deviation improved from original 76.9%, in the exotropia group being 77.8%. The overall success rate of the hang-back retroposition in all these patients was 77.1%. Ina group of children operated on by a traditional retroposition there was an overall success rate 78.7% (77.6% in esotropia and 82.4% in exotropia cases). Hang-back retroposition has been equally effective as the traditional retroposition of oculomotoric muscles. Its main advantages include visibility of the operation field, minimum risk of perforation of sclera and a fair time factor of the intervention. The authors discuss the development, indications, further advantages but also possible disadvantages or limitations of this acknowledged surgical procedure in strabology.
在一项临床研究中，作者评估了通过后徙复位法对眼外肌进行手术的效果。总共对70名儿童进行了手术，其中52例患有内斜视，18例患有外斜视。内斜视患者术前平均斜视度为30±12三棱镜度，术后斜视度在6±7三棱镜度范围内。在外斜视病例中，术前斜视度改善率为76.9%，在外斜视组中为77.8%。所有这些患者采用后徙复位法的总体成功率为77.1%。在一组采用传统复位法进行手术的儿童中，总体成功率为78.7%（内斜视病例中为77.6%，外斜视病例中为82.4%）。后徙复位法与传统的眼外肌复位法效果相当。其主要优点包括手术视野清晰、巩膜穿孔风险最小以及手术干预时间合理。作者讨论了这种公认的斜视手术方法的发展、适应证、进一步的优点以及可能存在的缺点或局限性。
