Visual field testing method and apparatus using virtual reality

摘要

A method and apparatus are disclosed for using Virtual Reality for testing and quantifying visual information from the eye, the visual pathways, and the brain. Head-gear 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. Interactive sensory feedback both to and from the patient enables computer-driven presentation and 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 and body, thus minimizing or even eliminating the stress and fatigue common with conventional non-Virtual Reality visual field testing systems.
