摘　　要：目的:探讨间歇性外斜视术前远立体视觉与手术量的关系,以期间歇性外斜视术后正位率更高。方法:回顾性分析我院按常规手术量矫正的间歇性外斜视患者病例资料,查验其术前有无远近立体视觉及术后眼位情况;另对间歇性外斜视中具有远立体视患者进行手术量调整的研究。结果:术前无立体视觉和只有近立体视觉的患者,术后正位率差异无统计学意义(P>0.05)。而术前有远立体视者,其术后正位率与术前无立体视及只有近立体视者差异均有统计学意义(P<0.01)。本资料中,术前有远立体视觉的患者均在常规手术量的基础上适当减少手术量,术后眼正位率与术前无立体视及仅有近立体视而采用常规手术量的患者相比较差异均无统计学意义(P>0.05)。结论:根据术前远立体视的存在与否,调整间歇性外斜视的手术量,可提高一次手术成功率。Objective： To study the correlation between the operative quantum and the preoperative far stereopsis for intermittent exotropia. Method： Forty-seven cases of intenrtittent exotropia received conventional operative quantum. Whether they had far and near stereopsis before operation and their postoperative eye positions were reviewed. Resuits： There were no significances of the postoperative orthotropia between the groups of having no stereopsis and only having near stereopsis （ P 〉 0.05）, but there was a significance between the groups of having far stereopsis and having no stereopsis or only near stereopsis（ P 〈 0.01 ）. Twenty-six eases of far stereopsis were dealt with reduced operative quantum, and their postoperative orthotropia had no differences from those had no stereopsis or only had near stereopsis dealt with conventional operative quantum（ P 〉 0.05）. Conclusion： Modulating the operative quantum may improve the success rate of operation for intermittent exotropia on the base of having far stereopsis or not.
