Others have suggested that developmentally delayed children, who are frequently esotropic, have a poor prognosis following esotropia surgery. To date, no comparison of success rates in normal and delayed children following similar surgery has been made. We compared our long-term results following graded bilateral medial rectus recessions in consecutive normal (n = 62) and delayed (n = 29) children. We defined success as alignment maintained within 10 delta of orthophoria. Survival curves were compared using the Mantel-Haenszel statistic. Delayed children had a significantly poorer outcome (p = .05) throughout follow up, which ranged from 12 to 120 months (mean = 24 months). Early in the period of study, we observed a large proportion of overcorrections among the delayed children. Subsequent modification in the amount of surgery performed appeared to improve the initial and long-term success in these children. We conclude that delayed children do have a poorer prognosis than normal children following medial rectus recession. This prognosis may be improved by more conservative amounts of surgery.
其他人指出，发育迟缓的儿童经常患有内斜视，他们在内斜视手术后预后较差。迄今为止，尚未对正常儿童和发育迟缓儿童在接受类似手术后的成功率进行比较。我们比较了连续的正常儿童（n = 62）和发育迟缓儿童（n = 29）在接受双侧内直肌分级后徙术后的长期结果。我们将成功定义为维持在正位视10棱镜度以内的眼位正位。使用Mantel-Haenszel统计量比较生存曲线。发育迟缓儿童在整个12至120个月（平均24个月）的随访期间预后明显较差（p = .05）。在研究初期，我们观察到发育迟缓儿童中有很大一部分出现过矫。随后对手术量的调整似乎改善了这些儿童的初期和长期手术成功率。我们得出结论，发育迟缓儿童在内直肌后徙术后的预后确实比正常儿童差。通过更保守的手术量，这种预后可能会得到改善。
