Two methods have been devised to assess the relative tensions required to point the eye in a given direction. One method uses an ophthalmotrope, which will assess the tensions and the lengths of the muscles. The second uses a computer program. In each method the direction of the eye is analyzed into components of elevation, azimuth, and cyclorotation. Such a combination of devices is needed in finding the patterns of innervation involved in Listing's law, cyclorotation associated with convergence, and also cocontraction associated with convergence.
已经设计出两种方法来评估将眼睛转向特定方向所需的相对张力。一种方法使用眼球旋转器，它可以评估肌肉的张力和长度。第二种方法使用计算机程序。在每种方法中，眼睛的方向都被分析为仰角、方位角和旋转分量。在寻找与利斯廷定律、与集合相关的旋转以及与集合相关的共同收缩中所涉及的神经支配模式时，需要这样一种设备组合。
