摘要
A simple and relatively inexpensive system has been developed for screening people both with normal vision and those with ocular and optic nerve disease using the Pulfrich stereo-illusion phenomenon. The system uses an audio/visual recording showing a ballerina moving in a pendulum fashion in front of a cone. The person to be tested uses a device which sequentially has no filters and filters of varying density whereby the patient with normal vision will see the ballerina moving back and forth in front of the cone and then rotating around the cone clockwise and counter-clockwise. The audio/visual recording may be shown to the person to be tested on a television set or a tv monitor.
