Among 78 children who had undergone surgery for intermittent exotropia, undercorrection was found in 39, an acceptable result in 33 and overcorrection in 6. A review conducted to determine what factors might explain the high frequency of undercorrection showed that the average age of the patients was higher than usual, and this was a significant prognostic factor. The presence or absence of associated hypertropias, lateral incomitance and A or V patterns was not of prognostic importance. Purposeful overcorrection of the exodeviation by 10 to 15 prism diopters tended to ensure a more satisfactory result.
在78例接受间歇性外斜视手术的儿童中，发现39例矫正不足，33例结果可接受，6例矫正过度。一项旨在确定哪些因素可能解释矫正不足高发生率的回顾显示，患者的平均年龄高于通常情况，这是一个重要的预后因素。是否存在相关的上斜视、外展功能不全以及A或V征并不具有预后意义。有意识地将外斜视过度矫正10至15棱镜度往往能确保获得更满意的结果。
