Abstract
We simultaneously measured the light being absorbed at every location across a patch of fresh excised primate retina. Rod and cone axial absorptances were 0.5 and 0.3 respectively, consistent with the specific density of photopigment and outer segment length. The photometric quantum efficiency of patches of peripheral retina was 0.12. There was little evidence for directional sensitivity in patches of rods. Great care must be taken when interpreting bright spots in images of excised retina.
