Assessment of stimulus field size for strabismic amblyopes.
Recently, small-screen measurements have suggested different types of visual loss in strabismic amblyopia. The present experiment examined the influence of field size on this conclusion for low- and high-frequency measurements. The original findings are believed to be independent of the grating field size, because (1) in the present study of 4 amblyopes, normal and amblyopic eyes were affected equally by increasing the number of cycles, and (2) the amblyopes' foveas did not have high-frequency discrimination superior to that of the eccentric area used for fixation.
