In a series of 27 patients who were operated on for esotropia, we compared patient response to surgery and the distance the medial recti were recessed from the insertion and corneoscleral limbus. We found a much more significant correlation between the response and the amount the muscles were recessed from the insertion than from the corneoscleral limbus. Using partial correlation coefficients, we found that when we corrected for the amount of recession from the insertion, there was not a significant correlation between the response to surgery and the amount the muscles were recessed from the corneoscleral limbus. This suggests that the apparent correlation between the response to surgery and the amount of recession from the corneoscleral limbus simply reflects that the greater the recession from the corneoscleral limbus, the farther the muscle is likely to end up posterior to the insertion.
在一组接受内斜视手术的27例患者中，我们比较了患者对手术的反应以及内直肌从附着点和角巩膜缘后退的距离。我们发现，反应与肌肉从附着点后退的量之间的相关性比与从角巩膜缘后退的量之间的相关性更为显著。使用偏相关系数，我们发现，当校正从附着点后退的量时，手术反应与肌肉从角巩膜缘后退的量之间没有显著相关性。这表明，手术反应与从角巩膜缘后退的量之间的明显相关性仅仅反映了从角巩膜缘后退的距离越大，肌肉最终可能在附着点后方的位置就越远。
