摘要
目的探讨间歇性外斜视患者屈光参差的特点及其对视功能的影响。方法对1149例间歇性外斜视患者中筛查出合并有屈光参差的285例患者资料进行回顾性总结和分析，根据屈光状态分为近视性、远视性、近视散光性、远视散光性和混合性屈光参差。观察项目包括患者的视力、屈光状态、Titmus立体视功能。结果（1）间歇性外斜视合并屈光参差的检出率为24．80％，以近视性和近视散光性屈光参差所占比例较高，分别为11．31％和8．09％。（2）屈光参差类型和屈光参差度对视力的影响差异有统计学意义（P〈0．05），远视和远视散光性屈光参差对视力的影响较大，屈光参差度越大对视力的影响越大。（3）屈光参差度对立体视功能的影响差异有统计学意义（P〈0．005），立体视锐度损害程度与屈光参差度相关。结论间歇性外斜视较多合并近视性和近视散光性屈光参差，屈光参差度与视力、立体视功能密切相关。
Objective To investigate the characters of intermittent exotropia combine with anisometropia and the impact on the binocular vision：Method 1149 cases with intermittent exotropia were summarized retrospectiveiy, selecting 285 anisometropia cases.According to the refractive status divide into myopia,Hypertropia,myopia astigrnatism,hypertropia astigmatism and mixed anisometropia.The data were recorded and anaiyesd,including visual acuity, the refiactive status, titmus stereopsis.Result （ 1 ）intermittent exotropia combine with anisometropia prevalence was 24.800/0, myopia and myopia astigmatism have a high prevalence （11.31% and 8.09% ）. （2）the effect of the degree of anisometropia and the refractive status on the visual acuit have statistically different（P 〈0.05 ）, Hypertropia and hypertropia astigmatism anisometropia were significantly impact on visual acuit. （3）the effect of the degree of anisometropia on the stereopsis have diference significant （P 〈0.005）.Conclusion myopia and astigmatism anisometropia combine with intermittent exotropia have a high prevalence, binocular vision deterriorates as anisometropia increases.
