目的研究注视差异在评价和分析双眼视功能中的作用,探寻更加准确合适的反映眼部功能的检查方法,同时为异常双眼视的临床诊断和治疗提供参考.方法横断面研究.对2013年3月至2013年9月,在天津医科大学眼科医院选取志愿参与研究的在校大学生80名,男34人,女46人,平均年龄(22.3±3.2)岁,使用电脑验光仪和综合验光仪分别进行客观及主观验光,在全矫基础上于40 cm处,应用Wesson Fixation Disparity Card配合偏振片测量由不同棱镜诱导下的注视差异的大小和方向,并绘制注视差异曲线.应用随机点立体视觉检查图进行立体视锐度的检查.让被检者阅读纸质文本材料半小时,使用视疲劳评估表评估视疲劳程度.分析注视差异与双眼视功能各项参数的关系.结果不同注视差异曲线类型所占比例不同,Ⅰ型、Ⅱ型、Ⅲ型和Ⅳ型所占比例分别为46％(37/80)、9％ (7/80)、26％ (21/80)和19％ (15/80).注视差异的大小与立体视锐度具有相关性,差异有统计学意义(rs=-0.350,P=0.004).注视差异曲线斜率与视疲劳程度具有相关性,差异有统计学意义(rs=0.857,P=0.000).结论注视差异是评估某些双眼视功能的有效方法,注视差异的测量结果可以辅助诊断临床异常双眼视功能.

Objective To study the role of fixation disparity in analyzing binocular visual function and find a better exam method to value visual function and to provide information in clinical diagnosis and treatment.Methods Eighty students aged 19-25 years old were randomly selected.Measure the prism-induced fixation disparity of students at distance of 40cm after routine optometric exams was performed.Stereo-acuity was measured by digital stereoscopic test charts.Eyestrain evaluation form asking about their level of ocular discomfort was taken after thirty minutes reading.The relationship between parameters of fixation disparity and binocular visual function were analyzed through cross-sectional study.Results Different type of fixation disparity curve had different percentage.Type Ⅰ,typeⅡ,typeⅢ and type Ⅳ were present in 46％(37/80),9％(7/80),26％(21/80) and 19％(15/80) of the population respectively.Fixation disparity was correlated with stereo-acuity (rs=-0.350,P =0.004).Further,the slope of fixation disparity curve was found to be correlated with eyestrain (rs=0.857,P =0.000).Conclusions Fixation disparity curve is a vital and effective way to value certain binocular visual function.It can support the diagnosis of abnormal binocular visual function.
