We examined the changes in Listing's plane resulting from prismatically induced vergence. The three-dimensional angular positions of the two eyes were compared in normal subjects wearing search coils and gazing at targets 1.9 m away with and without prisms. For horizontal base-out prisms each degree of convergence in one eye yielded 0.72 deg of temporal rotation of Listing's plane in that eye. The results from vertical prisms were not what was expected from the horizontal results. A base-up prism on the right eye induced a downward and temporal rotation of Listing's plane. A base-down prism on the right eye induced an upward and nasal rotation of Listing's plane. The effects of oblique prisms were those expected from combining the effects of horizontal and vertical prisms. Thus in addition to producing a horizontal or vertical misalignment of the gaze line, prisms induce an unexpected position-dependent torsional disparity.
我们研究了棱镜诱导性聚散引起的Listing平面的变化。在佩戴搜索线圈并注视1.9米远处目标的正常受试者中，比较了双眼在有棱镜和无棱镜情况下的三维角位置。对于水平底向外棱镜，一只眼睛每1度的聚散会导致该眼睛的Listing平面产生0.72度的颞侧旋转。垂直棱镜的结果与水平结果预期的不同。右眼的底向上棱镜会导致Listing平面向下和颞侧旋转。右眼的底向下棱镜会导致Listing平面向上和鼻侧旋转。斜棱镜的效果是水平和垂直棱镜效果的组合。因此，除了使视线产生水平或垂直偏移外，棱镜还会引起意想不到的位置依赖性扭转差异。
