Abstract: A system for testing and quantifying visual field and other visual function information in a head-mounted virtual reality environment, utilizing a directed image formation device for scanning of an image onto the retina of the test subject. A method and an apparatus are also provided for utilizing a central neural network and a central data bank to perform automatic interpretation of the visual function test parameters obtained in a plurality of visual field testing systems, for a plurality of patients, with control and response signals being transmitted via the Internet. The data produced by the testing systems are automatically analyzed and compared with patterns on which the neural network was previously trained, and clinical diagnoses for pathological conditions are thereby suggested to the respective clinician for each patient.

Abstract: A method and apparatus for testing the visual field of a patient, with a head mounted display, which displays a central fixation icon and a variable peripheral stimulus icon, and which senses the responses of the patient by tracking the gaze of the patient, as the gaze shifts between the central fixation icon and the peripheral stimulus icon.

Abstract: A system and method for automatically interpreting the results of visual field tests with a computer programmed to perform a continuously updated protocol derived from the interpretation of numerous visual field tests by experts in interpretation of visual field test results.

Abstract: A method and an apparatus for the performance and autointerpretation via the Internet, or other telemetric vehicle, of the visual function test parameters obtained during interactive visual field screening utilizing a local display screen. Such interactive testing and instantaneous autointerpretation of visual field performance utilizing a local display screen, via telemedicine, are utilized to screen for glaucoma and other neurological disorders affecting the visual system. Telemedicine, such as via the Internet, allows the system to be employed on a world-wide basis, including areas where physicians are not present.

Abstract: A method and apparatus are disclosed for using virtual reality to present a test stimulus of a first color superimposed on a background of a second color, for testing and quantifying visual information from the eye, the visual pathways, and the brain. Headgear 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.
