方法：临床纳入我院2013-09/2015-04期间收治的146例间歇性外斜视患者作为研究对象，根据间歇性外斜视患者的不同分型分为三组。分开过强型患者54例作为分开过强组； 基本型患者48例作为基本组； 集合不足型患者44例为集合不足组。分析三组患者视功能情况以及术后眼位矫正情况。

结果：术前三组患者视功能无差异，术后三组患者视功能均有所好转并仍无统计学差异(P>0.05)。分开过强组、基本组以及集合不足组正位率分别为83.3%、81.2%以及54.6%。分开过强组与基本组之间无统计学差异(P>0.05)； 分开过强组、基本组与集合不足组均有显著统计学差异(P<0.05)。

结论：间歇性外斜视根据分型不同手术类型不同，其中以分开过强型和基本型预后较好，集合不足型预后较差。但由于三种类型的斜视对应手术方式不同，如何进一步排除手术因素的影响是今后研究的重点内容。

METHODS: Totally 146 patients with intermittent strabismus treated in our hospital from September 2013 to April 2015 were enrolled in the study. The patients were divided into three groups according to the different types of the patients with intermittent strabismus. Fifty-five patients who had been separated from the strong type were used as part of the strong group,the basic type of 48 cases as the basic group,44 cases of collection insufficiency patients were set up as collection insufficiency group. Visual function and postoperative eye correction of the three groups were analyzed.

RESULTS: There were no differences in visual function among the three groups before operation, and the visual function of the three groups were improved after operation, and there was no difference among the three groups(P>0.05).The positive rates were 83.3%,81.2% and 54.6% of the strong group, basic group and collection insufficiency group respectively. There was no difference between the strong group and basic group,(P>0.05).There were significant differences between the strong group, basic group with collection insufficiency group(P<0.05).

CONCLUSION: Operations for intermittent external strabismus is different according to different types. The prognosis of the strong group and basic group is good and the prognosis of collection insufficiency group is poor.
