We therefore constructed appropriate annular zones in the macula for percentage (multiplicative) increases in brightness to be empirically determined using published data on the spatial distribution of macular pigment [ 29 30 ] . These observers found that the macular pigment density (hence optical density) is greatest centrally, drops to half-maximum within a diameter of 500 to 600 μm, reaches a quarter-maximum at a diameter of about 1000 μm, and thence tapers slowly to a low constant level within a 2000 μm diameter region.
The regions studied were the central 1000-micron diameter circular subfield and the 3000-micron outer diameter annular subfield (with 1000-micron inner diameter) centered on the fovea (the 1500 micron diameter anatomical center of the macula).
