Description
Color vision deficits have been reported in multiple sclerosis (MS) in the absence of optic neuritis (ON). Demyelination of the optic nerve in ON probably causes color-vision deficits by affecting the parvocellular-Red/Green (PC/RG) and koniocellular-Bue/Yellow (KC/BY) pathways. The evidence for selective deficits in PC/RG versus KC/BY pathways, however, is inconclusive. Moreover, the mechanism of color vision deficit in MS without ON demyelination is unclear. In this study we investigate color vision deficits in early versus late MS in the PC/RG versus KC/BY pathways.
