单眼外退-内截手术矫正间歇性外斜视效果分析

A Clinical Analysis of Unilateral Recession-resection Surgery in Intermittent Exotropia

目的对比分析间歇性外斜视单眼外退-内截手术效果、外退-内截各1mm平均矫正量、视远视近矫正效果的差异。方法对96例间歇性外斜视患者行单眼外退-内截手术,对术后远期眼位、平均矫正量和视近视远手术效果差异进行统计学分析。结果功能治愈58例(60.42%),临床治愈89例(92.71%);基本型、集合不足型及外展过强型外斜视患者手术后视远视近斜视角差异较手术前视远视近斜视角差异明显减小,差异有统计学意义(P<0.05)。平均矫正效果与术前斜视度呈负相关(P<0.05);平均矫正效果与手术量呈正相关(P<0.05);与手术年龄、发病年龄无相关性。结论间歇性外斜视单眼外退-内截手术设计应考虑术前斜视度对平均矫正量的影响,外退-内截手术可以较好的矫正远近斜视度的差异。

Objective To Study the unilateral recession-resection surgery（R-R）outcome,surgical dose of（R-R）1 mm,the different surgery effect between fixation far and near.Methods A retrospective study in 96 intermittent exotropia patients underwent R-R surgery,analysis the outcome;the influence factors of the dose of（R-R）1 mm;the different effect between fixation at 5 m and 33 cm.Results The functional cure ratio：58/96（60.42%）;the clinical cure ratio：89/96（92.71%）;The LR-MR can decrease the deviation angle difference between fixation at 5 m and 33 cm（P0.05）.Surgical dose（R-R）1 mm is liner correlated with preoperative deviation and surgical amounts（P0.05）.It is not correlated with age of surgery and age of onset.Conclusion If use unilateral recession-resection surgery procedure for intermittent exotropia should consider the deviation angle affect the surgical dose of（R-R）1 mm;This procedure successfully reduce both distance and near deviation and to collapse near-distance differences.
