Abstract
Visual field perimetry may be performed using virtual reality glasses, a computer, a printer and an external mouse. The advantages of such a system are price, portability and patient comfort. Virtual reality glasses containing an independent display for each eye allow both eyes to be tested at once. They also allow one eye to be used for fixation while the other eye is being tested. In order to maximize the use of the small screens of virtual reality glasses a moving fixation point is used. Predefined discrete targets are placed momentarily on the screen at angles calculated based on the current location of the fixation point. Patients respond to the targets by clicking a mouse button. Fixation monitoring is handled by blind spot monitoring of both eyes or by monitoring responses to a change in direction of the moving fixation point. Results in numerical or grayscale format may be sent to a computer screen or printer.
