PURPOSE Age effects on binocular summation, a cortically mediated visual function, were compared for resolution acuity, contrast sensitivity (CS), and spatial interval (SI) hyperacuity. METHOD The binocular and monocular thresholds of healthy, optimally-corrected healthy young (mean age 21.3 years) and old (mean age 69.9 years) observers were determined for acuity, SI discrimination, and CS at 1.0, 2.0, 4.0, 8.0 and 18.0 c/deg. RESULTS No age effects were observed on monocular or binocular… CONTINUE READING
