Simple Quantitative Test for Acuity and Reliability of Binocular Stereopsis

Depth Perception as a Function of Age

“…(5) The Verhoeff stereopter uses the number of correct responses to a set of three bars at different distances (one of them closer or farther away) to measure the furthest distance at which the relative position of the three rods is seen correctly (Verhoeff, 1942).…”

Binocular Rivalry and Stereoscopic Acuity

“…I n the Howard test, only two rods are used (22). Verhoeff used the same principle, but bars of different width, thus eliminating the possibility of judging the relative position from the size of the retinal image (47). The examiner determines the greatest distance at which localization of the bars in 8 different combinations is possible.…”
