Abstract
Evoked potentials (EP) in response to phase-alternating gratings were recorded from normal and stereoblind or stereodefective subjects (adults and children) under monocular and binocular viewing conditions. The amplitude of the binocular EP exceeded the larger monocular EP in normal but not in stereodefective subjects, without regard to the respective amplitudes of the 2 monocular EP. An objective method for screening out defects of binocular vision is provided. EP recorded from a group of infants, 2 to 18 mo. old, suggest that a larger amplitude of the binocular EP, as compared with the monocular EP, is the norm even in the earliest period of life.
