Abstract: The computer-assisted moving eye campimetric device is a computer display of a moveable test grid having a central reference spot. The patient's eye is kept focussed on the spot by giving the patient the task of keeping the moving spot in a circle by operating a hand held mouse. With the patient's eye correctly focussed on the reference spot, target elements in the field of vision are successively illuminated and the patient reacts by pressing a button on the mouse. Failure to react indicates impaired vision at that point in the patient's visual field. The results are held in the computer memory and plotted out as a map of the patient's effective field of vision.

Abstract: The present invention provides an oculo-perimetric device for use in measuring the field of vision of a subject and comprises an extended area visual target 1 having a large plurality of generally regularly, angularly and/or radially, spaced apart individual target elements 2, disposed around a central reference target element 3 across substantially the whole of the area within a predetermined radial separation R from said reference target 3. The individual target elements 2 are provided with sequence indicating means 4 formed and arranged so as to define a visually discernible predetermined sequence for fixing of a subject's eye 5 on successive adjacent individual target elements 2. The central reference target element 3 is formed and arranged so as to be visually more prominent than the individual target elements 2.
