Stereoscopic depth perception utilizes the disparity cues between the images that fall on the
retinae of the two eyes. The purpose of this study was to determine what role aging and …

Purpose: A clinical diagnosis of stereoblindness does not necessarily preclude compelling
depth perception. Qualitative observations suggest that this may be due to the dynamic …

Stereoscopic depth was measured in central vision under photopic viewing conditions. Two
test lines, one appearing above the other, were briefly exposed and adjusted to match in …

Although the angular threshold (θ) for stereo-acuity is approximately the same for all viewing
distances (b), the corresponding linear depth intervals (Δb) are not: the depth intervals …

Background: There is a need for a stereotest with the following properties:(1) Natural
viewing conditions, ie stimulus contours visible for each eye alone, but no or hardly any cue …

purpose. Variation in stereoacuity was examined in a large group of observers with Snellen
acuity of 20/30 or less. methods. Threshold retinal disparity for 2.78× 2.28 rectangular test …

In order to understand the role of oblique retinal image disparities in the perception of
stereoscopic depth, we measured the depth perceived from random dot stereograms in …

We estimated the proportion of people that have defective stereo vision and are unable to
utilize stereo disparity information to perceive depth. Previous estimates have ranged …

Background. Measurement of stereoacuity at varying distances, by real or simulated depth
stereoacuity tests, is helpful in the evaluation of patients with binocular imbalance or …

An instrument is described which tests for the use of stereopsis by measuring how long it
takes for depth perception to begin (its latency) after a transition from monocular to binocular …
