Abstract

Binocular dissociation is the technique used for quantitative evaluation of binocular function. (Noorden, 1985) Several methods are now clinically available, such as stereoscope (major amblyoscope), vectograph (Titmus and Randot stereotests), anaglyph (TNO and Awaya aniseikonia test), and prism bars (Lang’s stereogram). (March et al, 1980) Recently, Nintendo family video game developed stereo animation, which applied another mechanism for binocular dissociation. The stereo patterns were shown alternately on the screen in 60 Hz and the goggle-stereoviewer was synchronized with the screen to occlude both eyes alternately. We were interested in this system and tried to interface it with IBM PC/AT to make our own stereograms for both clinical and research works.
