Stereo Acuity and Reconnaissance. Phase II: Development of a Foveal-Parafoveal Chromostereopsis Test.

Abstract

A Foveola/Parafoveal or circular staircase test (F/P CST) was designed, developed and evaluated. Three small sample populations (total of 30 observers) were used in investigations of stereoscopic acuity and chromostereopsis. Specific attention was paid to the effect of interchanging the color of the stimuli within the foveola and that within the fovea or parafovea. Marked individualistic effects and large chromostereoscopic changes were observed. The form of the test was that of a central 58 arc minutes disc surrounded by a spiral of wedges that gave the appearance of a circular staircase as viewed from above.
