目的：探讨单眼一退一截术(unilateral recess-resection，R&R)和双眼外直肌后徙术(bilateral lateral rectus recession，BLR-rec)治疗基本型间歇性外斜视的疗效差异。
方法：回顾性分析2013-01/2015-01在我院治疗的基本型间歇性外斜视患者89例，其中49例行单眼退截手术，40例行双眼外直肌后徙术。观察两组患者术后1d，1、6mo，1、2a时立体视功能及斜视度。
结果：两组患者术后1d，1、6mo，1、2a手术成功率、斜视度比较，差异均无统计学意义(P>0.05)，但手术成功率随着时间推移均不断降低。术后1d～2a，R&R组外斜漂移量为12.10±5.74PD，BLR-rec组外斜漂移量为7.78±4.21PD，差异有统计学意义(P=0.021)。R&R组较BLR-rec组更易引起外斜回退。两组患者近立体视均显著提高，两组组间近立体视提高情况比较差异无统计学意义(χ2=4.530，P=0.210)。
结论：BLR-rec术远期稳定性优于R&R术。

AIM:To explore the differences between unilateral recess-resection(R & R)and bilateral lateral rectus recession(BLR-rec)in the treatment of basic intermittent exotropia.
METHODS: A retrospective analysis of treatment of basic intermittent exotropia in 89 patients, in which 49 cases underwent unilateral recess-resection, 40 cases underwent bilateral lateral rectus recession of external rectus retroperitoneal surgery January 2013 to January 2015 in our hospital. The stereopsis and strabismus were observed in 1d, 1, 6mo, 1 and 2a after operation.
RESULTS: There was no significant difference in the success rate and oblique degree between the two groups after 1d, 1, 6mo, 1 and 2a(all P>0.05), but the success rate of the operation was reducing as time passed. After 2d of the operation, the drift of the R & R group was 12.10±5.74PD and the drift of the BLR-rec group was 7.78±4.21PD, the difference was statistically significant(P=0.021). The R & R group was more likely to cause lateral slanting than BLR-rec group. Two groups of patients with nearly stereopsis were both significantly improved, there was no significant difference between the two groups in the two groups(χ2=4.530, P=0.210).
CONCLUSION: The long-term stability of BLR-rec is superior to R & R.
