Optical density of human macular pigment

Foveal and parafoveal spectral sensitivities of the G cone mechanism were used to derive the difference spectrum for the macular pigment for 12 observers. Measurements of the peak density of the macular pigment were obtained with a shortened version of the same procedure for an additional 15 observers. The mean density for all 27 observers at 460 nm was 0.77 +/- 0.06 with a range of 0.21-1.22. The mean density is higher than that previously reported and, compared to the standard absorbance curve (Wyszecki and Stiles, 1967), the results indicate higher density values for wavelengths on the long wavelength side of the absorption maximum.
