A comparison of color and luminance discrimination in amblyopia

A Bradley, C Dahlman, E Switkes and K De Valois

Using isochromatic luminance gratings and isoluminant red-green color gratings, examined luminance and color discrimination in amblyopia were examined. Complete color and luminance contrast sensitivity functions were measured monocularly from each eye of six normal and six amblyopic observers. Similar spatial frequency-specific color and luminance discrimination deficits were found in five of the amblyopes. One amblyope with a slight luminance deficit showed no color deficit. It appears that color and luminance discrimination are similarly affected in most amblyopes when spatial factors are effectively controlled.
