Figure 3

Agreement between measures. a) The agreement between binocular gain or loss on high contrast acuity and low contrast acuity. b) The agreement between binocular gain or loss on SKILL dark chart acuity and contrast sensitivity. The central region indicates no binocular gain or loss on either measure. Points on the line bounding the central region and outside the region indicate binocular gain or loss on the measure(s) indicated along the axes. Points in the 3 regions along the 45 degree line show agreement between the two measures. The central region indicates no binocular gain or loss on either measure. Regions off the diagonal indicate gain or loss for one measure but not the other (the four arms of the cross) or loss on one measure and gain on the other (upper left and lower right regions).
