摘要:
In one example of the invention a patient display is provided on which a fixation graphic or video is shown in substantially the centre of the display, and then target graphics or video are shown at different positions on the display about the centre. A test subject is positioned in front of the patient display a known distance therefrom, and a camera captures an image of the test subjects eyes, to allow gaze direction determination to be performed. The captured images are displayed to a clinician user by a controlling test application, the clinician making a determination based on the images as to whether the test subject saw a target graphic or video when it was displayed. The clinician user then makes an appropriate input into the controlling test application, which also logs the position at which the target image was displayed. By displaying target graphics at multiple locations on the screen and logging the clinician inputs, the controlling test application is able to build up a plot of the peripheral vision field of the test subject. This plot can then be graphically displayed to the clinician user, and stored with the test results for future clinical use.
