方法：采用回顾性病例研究。对我院2010-06/2012-12采用显微镜下改良Parks切口联合直肌线状折叠术的共同性斜视患者105例157眼进行研究，分析其术后1wk； 1，3，6mo的斜视度数变化。

结果：术后1wk； 1，3，6mo斜视度与术前斜视度比较均有统计学差异(P<0.05)； 术后1wk与6mo斜视度比较无统计学差异(P>0.05)。所有患者无眼前节缺血、结膜愈合不良等并发症。

结论：改良Parks切口联合直肌线状折叠术治疗共同性斜视，术后效果满意，手术操作简单、创伤小、并发症少。

METHODS: In this retrospective case series, 105 patients(157 eyes)with concomitant strabismus from June 2010 to December 2012 were researched. All the patients adopted improved Parks incision combined rectus linear tucking under microscope. The change of strabismus degree before operation and postoperative at 1 week, 1 month, 3 and 6months were analyzed.

RESULTS: The data was dealt with SPSS 12.0. The designs were performed using rank test. It had statistical significance. The change of strabismus degree between preoperative and postoperative at 1 week, 1 month, 3 and 6 months were significantly different(P<0.05), after 1 week and 6 months, strabismus degree showed no significant difference(P>0.05). All patients had good effectiveness, without anterior segment ischemia, conjunctiva faulty union and other complications.

CONCLUSION: The improved Parks incision combined rectus linear tucking is satisfactory in treating concomitant strabismus. The operation is simple, and it decreases trauma and complications.
