Abstract
Visual acuity was measured for horizontal, vertical, and oblique grating target orientations in the fovea and at various retinal eccentricities along the vertical meridian. Acuity was higher in the fovea, higher for vertical and horizontal target orientations, and higher in the superior retinal regions. The difference between acuities for vertical and oblique targets was greater in the superior retinal regions. It was concluded that the oblique effect is channel-size dependent.
