“…If the deviations from a simple average position are caused by the output of the rivalry pathway, then the manipulations of that pathway should have predictable effects on seen position of stereoscopic contours. Verhoeff (1933) found that changing brightness did alter the perceived binocular position, but the experiment should be repeated in light of newer data.…”

“…However, it is an oversimplification to think that a stereopsis mechanism simply adds depth to one of the monocular images. Under some circumstances, in particular when binocular disparities are small, a contour will be seen in neither monocular location, but in an intermediate locus (e.g., Helmholtz, 1909Helmholtz, /1924Hering, 1920Hering, /1964Sheedy& Fry, 1979;Verhoeff, 1933; though see Kaufman &Arditi, 1976, for a contrary view). Even when it assumes this intermediate state, the final binocular percept is not a strict or constant average of the two monocular views.…”

“…A number of previous experiments on binocular visual direction (Barbeito & Simpson, 1991; Charnwood, 1949; Francis & Harwood, 1951; Hariharan-Vilipuru & Bedell, 2008; Mansfield & Legge, 1996; Ono & Weber, 1981; Verhoeff, 1933) assumed that the relative weighting of eye-position and retinal information from the two eyes is similar in the same subjects. The results of our experiments show that the contributions of the two eyes to eye-position and retinal information do vary similarly between the two eyes in most subjects.…”

“…Other studies showed either qualitatively (Charnwood, 1949) or quantitatively (Ding & Sperling, 2006, 2007; Francis & Harwood, 1951; Mansfield & Legge, 1996; Sheedy & Fry, 1979) that the retinal information from the two eyes contributes to perceived OVD. The results of these studies indicate that when the images in the two eyes differ in terms of luminance (Charnwood, 1949; Francis & Harwood, 1951; Verhoeff, 1933), contrast (Ding & Sperling, 2006, 2007; Mansfield & Legge, 1996), or blur (Charnwood, 1949), then the perceived OVD shifts towards the image with the higher luminance or contrast, or lesser blur, implying a differential weighting of the retinal information from the two eyes.…”

Relative contributions of the two eyes to perceived egocentric visual direction in normal binocular vision

Perceived egocentric direction (EVD) is based on the sensed position of the eyes in the orbit and the oculocentric visual direction (eye-centered, OVD). Previous reports indicate that in some subjects eye-position information from the two eyes contributes unequally to the perceived EVD. Findings from other studies indicate that the retinal information from the two eyes may not always contribute equally to perceived OVD. The goal of this study was to assess whether these two sources of information covary similarly within the same individuals. Open-loop pointing responses to an isolated target presented randomly at several horizontal locations were collected from thirteen subjects during different magnitudes of asymmetric vergence to estimate the contribution of the position information from each eye to perceived EVD. For the same subjects, the direction at which a horizontally or vertically disparate target with different interocular contrast or luminance ratios appeared aligned with a non-disparate target estimated the relative contribution of each eye’s retinal information. The results show that the eye-position and retinal information vary similarly in most subjects, which is consistent with a modified version of Hering’s law of visual direction.

“…It has also been shown that decreasing the mean luminance in one eye can also affect binocular functions, e.g. stereo-acuity111, dichoptic contrast detection121314, binocular space perception15, binocular rivalry16, binocular visual evoked potential1718, and binocular sensory dominance19. These results indicate that an interocular luminance difference can induce a functional imbalance between the two eyes in normal observers, reducing binocular function, altering interocular interactions and shifting sensory dominance to the eye with the higher luminance level.…”

The Effect of Unilateral Mean Luminance on Binocular Combination in normal and amblyopic vision

Luminance plays a modulating role in the processes of several visual tasks, which in turn provides significant information for the understanding of visual processing. Here, using a binocular phase combination paradigm, we studied the effect of unilateral changes in mean luminance on binocular combination in both normal and amblyopic vision. We found, in normal observers, attenuation of one eye's stimulus luminance with neutral density filters produces binocular phase combination similar to those of amblyopic subjects. Correspondingly, in amblyopic observers, reduction of the fellow eye's stimulus luminance produces binocular phase combination similar to those of normal subjects. These phenomena could be explained by an attenuated contribution of the filtered eye to the binocular phase percept due to reduced gain-control. The findings have major implications both for the study of binocular combination and for amblyopia treatment.
