Abstract
By photographing the corneal reflex in two positions of gaze and measuring the radius of curvature of the cornea it is possible to calculate the radius of rotation of the eye. The measurements obtained in this way showed a high correlation with refraction in a series of 80 eyes. The axial length obtained by this method was about 3 mm greater than that obtained by ultrasonographic or x-ray methods, and the reasons for the discrepancy are discussed.
摘要
通过拍摄两个注视位置的角膜反射并测量角膜的曲率半径，可以计算出眼球的旋转半径。用这种方法获得的测量结果与80只眼睛的验光结果高度相关。通过这种方法获得的眼轴长度比通过超声或X射线方法获得的眼轴长度大约长3毫米，并对差异的原因进行了讨论。
