From: Simplified automatic method for measuring the visual field using the perimeter ZERK 1
A comparison of the visual field for two types of perimeters: a Explanation of the angular accuracy of ZERK1 where 1 arms of ZERK1, 2 visual field, 3 the area of one LED, 4 position of patient’s eye; b Imposition of the results for the phantom where, 5 results obtained from the Heidelberg edge perimeter, 6 reference area for defects in the visual field, 7 results obtained using ZERK1, 8 colour palette of the threshold of eye sensitivity to stimuli expressed in dB
