Abstract

The visual field of 86 eyes of 18 normal Korean male and 25 female were measured by test objects for white 4/330, blue 8/330, red 8/330 and green 8/330 in 12 principal meridians with 31.5 apostilb of luminance. By using the above mentioned test objects, the range, mean, standard deviation and standard error of each isopter were calculated for determining limitation of normal visual field. 1. The widths of each isopter, which were observed at 4 meridians, were increased from the narrowest to the widest, 90 degrees, 180 degrees, 27 degrees and 330 degrees in order. 2. Visual fields of same visual angle against test object were increased in the order of green, blue and red. The widths of 4 visual fields were depressed in the order the white 4/330, blue 8/330, red8/330 and green 8/330. 3. The standard deviation and standard error of each meridian of visual fields, white was most reliable and blue, red and green in order. 4. Among 4 test objects the most reliable meridian was white 330 degrees and 90 degrees was the most reliable in blue, red and green. The poorest meridian in reliability were white 60 degress and in blue 180 degrees, in red and green 330 degrees.
