The first step in the semi-automated method was therefore to apply the above correction to the green channel of the standardized image if luteal pigment was present.
Causative genes for pigment dispersion remain to be identified [ 12, 15].
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.
Since we were dealing with photography, not photometry, the choice of multiplicative or additive correction attempted to preserve semi-quantitative relationships of reflectance rather than absolute levels or precise numerical relationships [ 31 ] . Further, since reflectance variability was at issue, rather than absolute levels, we considered only the most variable components: the macular luteal pigment, dealt with above, the nerve fiber layer [ 32 33 34 35 ] , and the RPE melanin [ 36 ] . The RPE melanin is denser in the fovea, and as such will reduce the reflectance of underlying drusen in much the same manner as the luteal pigment.
, pigment, retinal vessels) are ignored.
