Abstract
Light radiated from foveal photoreceptors was analyzed in the eye’s pupil at and . The reflectance of the inner limiting membrane was then measured at from the fovea for the same wavelengths, allowing us to determine the macular pigment (MP) density using the directional reflectance technique. In addition we measured the MP density using the nondirectional reflectance technique (26 subjects). The mean values of and were and , respectively (sample field of ). They were highly correlated . Comparison of and implies that of the light reflected from the fovea comes from layers anterior to MP at . The mean directionality factors ρ that we have measured at and were equal to and , respectively. They were correlated and followed the spectral dependence suggested by Marcos.
