Visual functions in a patient with acquired achromatopsia Subjectively, he reports that colours appear abnormal to him and his descriptions of surface colours are similar to those of other patients who suffer cerebral achromatopsia. His colour matching and two colour increment threshold data establish that his cone photoreceptors have normal spectral resp

The effects of sub-cortical and cortical damage on colour visionnt retinal units, at the ganglion cells or optic nerve fibres, abolishes all aspects of colour vision. Conversely, cortical lesions of primate visual area V4 affect only one aspect of colour vision, namely colour constancy leaving colour discrimination and simple categorization intact. The chromatic

In early and in mild cases, in which retinal function as judged by quantitative perimetry, threshold measurement and electroretinography is normal or nearly normal, there is a profound loss o
