ABSTRACT:
A method for examining a visual field of a subject includes the steps of stimulating the subject eye movement reflex to an off field visual stimulus and mapping the subject visual field based on a positive reflex to the stimulus. An apparatus (20) for evaluating the visual field of a subject (22) includes a subject affixation mechanism (24) for affixing a portion of the apparatus (20) to the subject (22), an eye tracking mechanism (26) operatively connected to the subject affixation means (24) for tracking eye movement of the subject (22), and visual field stimulus generater (28) operatively connected to the affixation mechanism (24) for generating a visual stimulus.
