Abstract

Flicker functions were obtained with square test fields of 1°, 2°, 5°, and 10° angular subtense positioned at the center of the blind spot. When the test fields fell entirely on to the disk, duplex flicker curves were obtained, indicating excitation of adjacent elements by scatter of light. The disk area was explored with small test fields presented in various positions on a vertical and a horizontal line running through the center of the blind spot. A drop in critical flicker frequencies was obtained when the test field fell into the disk area. The possibility of using the decrease in frequency as a measure of retinal dysfunction in scotomata is discussed.
