It is not only possible but safe to exceed the traditional 5 mm maximum recession of each medial rectus muscle to correct large angle esotropia. It is possible to grade the amount of recession to the preoperative deviation, similar to that which is done for esotropia less than 35 prism diopters. The results of this series indicate that alignment to within 10 prism diopters with one procedure is more likely by large recessions of the medial rectus than by other approaches. If a reoperation is necessary, there still remain two other untouched horizontal muscles on which to operate.
超过传统的每条内直肌最大后退5毫米以矫正大角度内斜视不仅是可行的，而且是安全的。可以根据术前斜视度数来分级确定后退量，类似于对小于35棱镜度的内斜视所做的那样。本系列结果表明，与其他方法相比，通过大幅度内直肌后退更有可能一次手术就将斜视矫正至10棱镜度以内。如果需要再次手术，仍有另外两条未动过的水平肌可供操作。
