OBJECTIVE PERIMETRY BY PATTERN SHIFT VISUAL EVOKED RESPONSES

A new device for objective perimetry using VERs evoked by the pattern shifter was developed. The amplitude of VERs was the highest at the center of the visual field and it was declined to the periphery like a probability curve. It revealed recognizable VERs from the peripheral visual field of 60° of nasal and 90° of temporal. This method was also evaluated in a case with concentric contraction of visual field and it was found to be equivalent to the snbjective perimetry. These evidences suggest that the kinetic stimuli are more effective than the static stimuli for the objective perimetry, since peripheral visual field is sensitive to a moving target.
