Spatial summation across the central visual field: Implications for visual field testing

open access: goldJournal of Vision, 2015
In the present study, we measured the extent of spatial summation in the detection of image contrast within the central 40° visual field. Contrast detection thresholds (in 28 observers) were measured for a spot of light of 10 different sizes [area: 0.03-1.92(°)(2)] at different retinal meridians (0°, 45°, 90°, 135°, 180°, 225°, 270°, and 315°) and ...
