摘要：

The ability to recognize small spots of colored light in parafoveal regions of the retina was investigated in women heterozygous for protanopia (2 subjects), deuteranopia (2 subjects), deuteranomaly (1 subject) and in 3 normal subjects. The homozygous color normals had excellent discrimination up to 8.degree. eccentricity, whereas in heterozygous carriers of congenital color vision deficiencies the ability to differentiate colors varied from point to point within the retina. The existence of alternating patches of trichromatic and dichromatic cell populations within the retina of the heterozygous carriers is assumed.
