AM-Three experiments were performed to examine positional acuity and the role of spatial sampling in central, peripheral and amblyopic vision. In the first experiment, 3-line bisection acuity was compared to grating acuity. In normal fovea1 vision bisection acuity represents a hyperacuity. In anisometropic amblyopes, bisection acuity is reduced in rough proportion to their grating acuity. In strabismic amblyopes, and in the normal periphery, bisection acuity is reduced to a greater extent han grating acuity. This result implies that reduced contrast sensitivity of the spatial filters is not sufhcient o account for the increased positional uncertainty found in peripheral vision and in strabismic amblyopia. In order to test the hypothesis tha...
