摘　　要：目的 探讨头位照相法测量水平方向双眼单视范围的可行性.方法 自身对照研究.在受检者框架眼镜颞侧绑定放置10△基底向下三棱镜,在侧方一定范围内产生垂直复视.根据三棱镜距离眼镜光学中心的距离不同,产生不同大小的双眼单视范围.选择3名受检者,受检者均具备良好双眼视功能.在1、2、3 m距离,分别用三棱镜制造不同复视范围各11次,每名受检者均分别采用视标移动法和头位照相法测量水平方向双眼单视的范围.采用Pearson相关分析和两因素方差分析进行数据检验.结果 2种方法均可测量水平方向双眼单视范围,视标移动法为14.3°±6.3°;头位照相法为15.5°±7.3°.2种方法测量结果之间具有高度相关性（r=0.943,P＜0.01）.在视标距离分别为1、2、3 m时,2种测量方法测量结果的比较显示,不同距离、不同方法之间差异无统计学意义（F=2.14,P＞05）.结论 参照点头位照相法可以用于评估水平方向的双眼单视范围,其测量结果与移动视标法一致。Objective To evaluate the effect of relative reference point photographic analysis on measuring horizontal binocular single vision.Methods Self-control study.A 10△ prism was added onto the temporal side of subjects＇ fully corrected glasses,which produced limited vertical diplopia.Different binocular single visual fields were produced by changing the distance between the prism rim and optical center of the glasses.Three subjects with good binocular vision were selected.At distances of 1 m,2 m and 3 m,different binocular vision fields were produced 11 times.Every subject need to complete the measurements.Moving visual targets and a photographic method were used to measure the horizontal single visual field.A Pearson correlation analysis and a two-way ANOVA was used to analyze data.Results The two methods could measure the horizontal field of single vision well.Horizontal single binocular fields measured with a moving target method were 14.3°±6.3° and were 15.5°±7.3° when measured by photographic methods.The Pearson correlation factor was 0.943.Two-way ANOVA showed the two methods were not significantly different when a visual target was at a distance of 1 m,2 m or 3 m （F=2.14,P〉0.05）.Conclusion Relative reference point photographic analysis can be used to evaluate the horizontal binocular single visual field.It is as accurate as the moving visual target method.
