Diagnosis of Normal and Abnormal Color Vision with Cone-Specific VEPs

PURPOSE Normal color vision depends on normal long wavelength (L), middle wavelength (M), and short wavelength sensitive (S) cones. Hereditary "red-green" color vision deficiency (CVD) is due to a shift in peak sensitivity or lack of L or M cones. Hereditary S cone CVD is rare but can be acquired as an early sign of disease. Current tests detect CVD but few diagnose type or severity, critical f...

Variations in normal color vision. I. Cone-opponent axes.

Early postreceptoral color vision is thought to be organized in terms of two principal axes corresponding to opposing L- and M-cone signals (LvsM) or to S-cone signals opposed by a combination of L- and M-cone signals (SvsLM). These cone-opponent axes are now widely used in studies of color vision, but in most cases the corresponding stimulus variations are defined only theoretically, based on ...

The L:M cone ratio in males of African descent with normal color vision.

Among Caucasian males with normal color vision, long-wavelength-sensitive (L) cones outnumber middle-wavelength-sensitive (M) cones by nearly three to one, on average, and the L and the M cone opsin genes are arrayed on the X-chromosome with the L opsin gene being closest to an upstream enhancer element termed the locus control region (LCR). Interaction between an opsin gene promoter and the LC...

Opsin genes, cone photopigments, color vision, and color blindness

In this chapter, we introduce the molecular structure of the genes encoding the human cone photopigments and their expression in photoreceptor cells. We also consider the consequences that alterations in those genes have on the spectral sensitivity of the photopigments, the cone photoreceptor mosaic, and the perceptual worlds of the color normal and color blind individuals who possess them. Thr...
