Abstract

A simple test based on the Pulfrich phenomenon may provide an indication of optic nerve dysfunction. When a small object swinging pendulum fashion is viewed binocularly by a person with one eye covered by a neutral density filter, the object appears to swing in an elliptical path. The patient with optic nerve dysfunction may see it this way without use of a filter. The Pulfrich theory is explained, clinical applications are discussed, and instructions for constructing a Pulfrich apparatus are given.

摘要

基于普尔弗里希现象的一项简单测试可能会提示视神经功能障碍。当一个小物体以钟摆方式摆动，由一只眼睛被中性密度滤光片覆盖的人双眼观察时，该物体似乎沿椭圆形路径摆动。视神经功能障碍的患者可能不使用滤光片也会看到这种情况。文中解释了普尔弗里希理论，讨论了临床应用，并给出了制作普尔弗里希仪器的说明。
