Abstract:

The primary cue to distance is stereopsis -- the ability of the brain to make use of the binocular parallax provided by the horizontal separation between the two eyes. Yet not all individuals can make full use of this cue. For these individuals, certain kinds of stimuli are incorrectly localized in depth. These observers, who possess reduced stereopsis, include about 30 of the population. The primary objective of this report is to present procedures and tests that will detect such individuals who have reduced stereoscopic abilities. The second objective is to describe the physiologic nature of the reduction of the normal stereoscopic mechanism. Author Modified Abstract
