Measurement of heterophoria of myopic youth by Von Graefe;
Von Graefe法测定近视青少年隐斜视
·METHODS:Eight hundred and ninety-three students aged 15-21 years were measured far and near heterophoria degrees by phorometer(Ma pole rotating prism),and three-dimensional vision including stereoacuity,cross-parallax,non-cross-parallax by "three-dimensional visual inspection map".
方法:对年龄15～21岁893例学生采用隐斜仪(马氏杆旋转三棱镜)测定远、近隐斜视度,采用"立体视觉检查图"测定立体视觉,包括立体视锐度、交叉视差、非交叉视差。
