Stereopsis and stereoblindness
Experimental Brain Research, 1970Psychophysical tests reveal three classes of wide-field disparity detectors in man, responding respectively to crossed (near), uncrossed (far), and zero disparities. The probability of lacking one of these classes of detectors is about 30% which means that 2.7% of the population possess no wide-field stereopsis in one hemisphere.

We have measured threshold disparity as a function of the spatial frequency (0.25-20 c/deg) and contrast (0.02-0.75) of sine-wave gratings. In forced-choice trials, subjects indicated whether a target grating had crossed or uncrossed disparity relative to a reference grating.

Our eyes capture different 2-D images of the objects around us and our brain uses these images to recover a description of the 3-D structure of the environ ment. Stereopsis is the process responsible for this reconstruction of the depth dimension in our visual world.

This paper reviews much of the basic literature on stereopsis for the purpose of providing information about the ability of humans to utilize stereoscopic information under operational conditions. This review is organized around five functional topics that may be important for the design of many stereoscopic display systems: geometry of stereoscopic ...

▪ Abstract Binocular disparity provides the visual system with information concerning the three-dimensional layout of the environment. Recent physiological studies in the primary visual cortex provide a successful account of the mechanisms by which single neurons are able to signal disparity.

Stereoscopic depth perception is demonstrated in the falcon, a nonmammalian with binocular vision. This result complements recent physiological evidence for binocular interaction in the bird visual system, and suggests that stereopsis may be a general attribute of vertebrate vision and not an exclusive product of mammalian evolution.

Stereopsis is a sensation sui generis which is to some extent independent of other visual functions. It is more than simply the “third degree of fusion.” It can occur in diplopia.

In comparison to lateral judgments of distance, stereoscopic judgments are not precise. Although stereoacuity thresholds for targets presented in the fixation plane can equal the best thresholds for the monocular hyperacuities, i.e. a few sec arc, the increment thresholds for disparity are substantially larger than the increment thresholds for lateral ...

HARKNESS'S demonstration1 that chameleons rely primarily upon accommodative cues to judge distance encouraged me to examine the mechanisms of depth vision in an amphibian (Bufo marius). Unlike chameleons which have highly mobile eyes, toads make neither convergent nor fixating eye movements, so that, except for stabilising reflexes, their eyes are ...

The perceptual correlates of sensory cyclofusion have received little attention. However, they are easily elicited by asking patients with torsion about perceived slant of the visual world, and by watching how they hold the Titmus or Randot book. Sensory cyclofusion induces two types of perceptual aberrations.
