[Effect of grid orientation of interference patterns on contrast sensitivity in white and colored light].
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.
