The response range of the blue-cone pathways: a source of vulnerability to disease

Invest Ophthalmol Vis Sci. 1984 Jul;25(7):864-7.

Abstract

Retinal disease preferentially affects the sensitivity of the "blue"-cone pathways. This vulnerability to disease may be due, in part, to a more limited response range. A psychophysical technique, the probe-flash paradigm, was used to test this hypothesis. The data suggest that the S-cone pathways have a more limited response range than the L-cone pathways. Explanations for blue-cone vulnerability are discessed in the context of this finding.
