The effects that lateral prisms have on the horopter were evaluated in 11 subjects, including 6 subjects classified as binocularly abnormal. For normal subjects with good stereopsis the equidistance (stereoscopic distance matching) horopter shape was altered with the application of lateral prism. For other subjects this was not the case. Equidirection (nonius) horopters were unchanged by the application of lateral prism in all of the subjects tested. In addition to localized irregularities in the horopter locus, shifts in fixation disparity produced regional distortions of the horopter.
在11名受试者中评估了外侧棱镜对双眼单视界的影响，其中包括6名被归类为双眼异常的受试者。对于具有良好立体视觉的正常受试者，应用外侧棱镜会改变等距离（立体距离匹配）双眼单视界的形状。而对于其他受试者则并非如此。在所有测试的受试者中，应用外侧棱镜后，等方向（对距离规）双眼单视界没有变化。除了双眼单视界轨迹中的局部不规则外，注视差异的变化还会导致双眼单视界的区域变形。
