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.
