  • Patent number: 5886770
    Abstract: A visual field test device (10) is disclosed which allows a larger area of the visual field to be examined and allows use of the device for testing for diseases of the eye and brain, for example, glaucoma. The device consists of a chart (12) which has visual target patterns (13) for the left and right eyes and which is foldable about fold line (45) so that the visual targets are on front and rear surfaces of the device (10). Each visual target consists of about 60 fixation targets (14), represented by sequential numbers, arranged to spiral outwards along lines (16) to facilitate use by test subjects. A plurality of test stimuli (21) are located on a rotatable disc (18) and the chart (12) has a central aperture (20) through which a selected test stimuli (21) can be viewed. Different test stimuli can be used as required and in one embodiment a moveable cover (22) can be used to obscure the test stimuli.
