Cone pigments in human deutan colour vision defects.

摘要: 1. The Nagel anomaloscope, neutral points and dichromatic matches to a spectral green light identified population of seventy red-green dichromats. 2. anomaloscope settings allow the calculation relative action spectrum match at wave-length red (645 nm) (535 primaries. distribution this ratio is bimodal; there are two clusters with gap about 0-75 long units between. Among thirty-eight deuteranopes wide differences in matches; similar appear among thirty-two protanopes. 3. Retinal densitometry foveas fifteen compared contrasted measurements on trichromats. In former, only one photolabile pigment found region spectrum; normals always have two. view Rushton (1965a) that erythrolabe but no measurable chlorolabe confirmed for each member group. 4. Simple deuteranomalous show cone pigments. difference spectra extreme very those deuteranopia. 5. Individual differnce kinetics (photosensitivity, time constant regeneration) density lambdamax deuteranopia appreciable; reasons these not clear.
