目的：探讨不同手术年龄的间歇性外斜视患者术后双眼视功能的恢复情况。

方法：选取2016-01/2018-01在我科住院行斜视矫正术的间歇性外斜视患者172例，其中男95例，女77例，年龄3～32岁(平均11.4±1.5)岁。间歇性外斜视患者均为基本型。根据手术年龄分为两组：≤9岁组(90例)和>9岁组(82例)。术前和术后1、7d，1、3mo，采用同视机检查双眼视功能，Titmus检查近立体视。

结果：≤9岁组患者的同时视功能、融合功能、融合范围、远立体视、近立体视随术后时间的增长恢复效果优于>9岁组患者(P<0.05)。

结论：间歇性外斜视患者建议在9岁前手术治疗，尽早手术有利于术后双眼视功能更好地改善。

METHODS: Totally 172 patients with intermittent exotropia who underwent strabismus correction in our department from January 2016 to January 2018 were selected, including 95 males and 77 females, aged from 3 to 32 years, with an average age of 11.4±1.5 years. All patients with intermittent exotropia were basic type. According to the age of operation, the patients were divided into two groups: the group of less than 9 years old(90 cases)and the group of more than 9 years old(82 cases).The preoperative, 1d, 7d, 1mo and 3mo after operation were observed. The function of binocular vision was examined by synoptophore and myopia was examined by Titmus.

RESULTS: A comparison of simultaneous vision: at the same time, the visual function, fusion function, fusion range, far stereo, near stereo recovery effect of patients ≤9 years group was better than that of patients >9 years group. The difference was statistically significant(P<0.05).

CONCLUSION:Suggested surgical treatment of intermittent exotropia before 9 years old. Early operation is conducive to better improvement of binocular vision after surgery.
