The binocular visual field is defined for this study as the area of overlap of Goldmann perimeter field charts. Two groups of normal individuals were studied: 146 subjects aged 20 to30 years and 129 subjects aged 15 to 75. Monocular fields were measured with the 1-2, 1-3 and 1-4 stimuli, then digitized so the area of the monocular and binocular fields could be computed. Average binocular field isopters were plotted, and show a considerable inferior enlargement of the binocular field for young people with the Goldmann 1-4 target, which tends to decrease markedly with age. The rate of decreased of the binocular visual field with age is roughly 25% slower than that for the monocular visual field.
