Abstract
Nearly half a century ago it was suggested that absolute sensitivity of photoreceptors depends on the rhodopsin content of rod outer segments in a simple photochemical way: a decrease in rhodopsin concentration causes a proportional decrease in the probability of quantal absorption and hence leads to a proportional loss in sensitivity. From measurements of rhodopsin concentration and sensitivity in the eyes of man (RUSHTON et al., 1955; RUSHTON, 1961) and rat (DOWLING, 1960, 1963) it became evident that this early hypothesis was not true: in both human and rat eyes, an approximately linear relationship between log sensitivity and rhodopsin concentration was found. The slope \( \left( {\frac{{\Delta \log s}}{{\Delta {c_R}}}} \right)\)of this relation varies from species to species. The highest value, \( \left( {\frac{{{R_{\Delta \log s}}}}{{\Delta {c_R}}}} \right) = 6\) was reported for the retina of the albino rat. In this retina, a decrease of 17% in rhodopsin concentration reduces the sensitivity to 1/10; a decrease of 34% reduces the sensitivity to 1/100 and so on (WEINSTEIN et al., 1967). Whereas the sensitivity is greatly decreased, the probability of quantal absorption is only slightly reduced.
