Our experiment was directed at the inference that abnormal Stiles‐Crawford curves for amblyopic eyes indicate malorientation of foveal receptors which in turn is presumed to be the two eccentric fixators showed the usual abnormal curves. One of our eccentric fixators later developed foveal, or near foveal, fixation and his Stiles‐Crawford curve became essentially normal. These results, together with recent findings from other studies, lead us to conclude that although abnormal Stiles‐Crawford curves exhibited by amblyopic eyes may indicate orientation of retinal receptors away from the center of the entrance pupil either in the fovea or parafovea (in cases of eccentric fixation), such maloriented receptors cannot account for the acuity loss in amblyopia. Thus, there is little basis for the notion of receptor amblyopia.
Marshall et al. (Sun,) studied this question.
