The contrast sensitivity of 34 healthy eyes and 32 suspected of having glaucoma was measured at 3, 6, 12, 18, and 24 cycles/degree with vertical, oblique and horizontal interference fringes. These were produced by the Haag-Streit Visometer as modified by Lotmar with an additional device for contrast variation. At all frequencies, maximum contrast sensitivities were found for vertical gratings. However, there was a tendency for oblique gratings to show relatively low contrast sensitivities at high spatial frequencies; the same applied for horizontal gratings at low frequencies. The effect of stimulus orientation was similar for white, red, green and blue light.
使用垂直、倾斜和水平干涉条纹，在3、6、12、18和24周/度的条件下，测量了34只健康眼睛和32只疑似青光眼眼睛的对比敏感度。这些是由经洛特马尔改进的哈格-施特赖特视力计产生的，该视力计还配备了一个用于对比度变化的附加装置。在所有频率下，垂直光栅的对比敏感度最高。然而，倾斜光栅在高空间频率下往往显示出相对较低的对比敏感度；低频下的水平光栅也是如此。白色、红色、绿色和蓝色光的刺激方向效应相似。
