Binocular interaction in visual evoked potentials (VEPs) and subjective visual perception was analyzed by static random-dot stereograms the input of which to each eye was made unequal by binocular misalignment through a prism. Each eye was separated by a red-green glass. When binocular correspondence of the random-dot patterns was achieved by motor fusion, stereopsis was well perceived and VEPs showed binocular summation. When visual input to the two eyes was highly different in retinal correspondence, the visual input from one eye was suppressed, yielding no VEP summation, and only monocular viewing was perceived. In two other conditions, the eyes interfered with each other, creating retinal rivalry and inhibitory binocular interaction in VEPs.
