Cortical Deficits in Human Amblyopia: Their Regional Distribution and Their Relationship to the Contrast Detection Deficit

Abstract

The results suggest that there are significant suprathreshold processing deficits that are not a consequence of the well-known threshold deficit. Our preoccupation over the past 30 years with the contrast detection deficit in amblyopia limited to the processing within a circumscribed part of V1 may have to be modified to include not only processing deficits for high-contrast stimuli but also the involvement of multiple extrastriate areas.
