| 摘要 |
The present invention is a method and apparatus for using virtual reality on screen display (12a) to present a test stimulus of a first color superimposed on a background of a second color, for testing and qualifying visual information from the eye, the visual pathways, and the brain. Headgear (12) configuration allows the patient to observe a field of view into which sequenced test stimuli are presented by an excitation device commanded by a computer (13). Interactive sensory feedback both to and from the patient enables computer driven presentation, modulation of test stimuli to measure with precision such parameters as visual field performance, visual acuity, and color vision. Using the system allows the patient unprecedented freedom of movement of the head, body minimizing or even eliminating the stress, and fatigue common with conventional non-virtual reality visual field testing systems.
