Two measurable effects are produced by viewing a large disk rotating about the line of sight: a perceived displacement of the apparent horizon (tilt) and cyclotorsion of the eye (torsion). Previous results in our laboratory (see Refs.) using dichoptic presentation techniques show that both effects demonstrate binocular enhancement in normal subjects. Further, stereoblind subjects maintain enhancement for the oculomotor effect, torsion, but not for the perceptual effect, tilt. In this study we have found that this stereoblind pattern of results can be produced optically in normals by introducing a three diopter myopia in one eye. This renders the subject stereoblind and causes suppression of the artificially myopic eye. In this condition torsion still shows enhancement; tilt does not. This procedure may be useful in isolating causes of stereoblindness and in locating different sites of binocular interaction.
视地平线的感知位移（倾斜）和眼睛的旋转扭转（扭转）。我们实验室之前使用双眼分视呈现技术的结果（见参考文献）表明，这两种效应在正常受试者中都表现出双眼增强。此外，立体视觉盲的受试者对动眼效应（扭转）保持增强，但对视知觉效应（倾斜）则不然。在本研究中，我们发现通过在一只眼睛中引入3屈光度的近视，可以在正常人中通过光学方式产生这种立体视觉盲的结果模式。这会使受试者成为立体视觉盲，并导致人工近视的眼睛受到抑制。在这种情况下，扭转仍然表现出增强；倾斜则不然。这个过程可能有助于分离立体视觉盲的原因，并定位双眼相互作用的不同部位。
