Figure 7. — Eccentricity-wise analysis of band 2 reflectivity in 12 eyes of 12 subjects. Regional profiles were aligned according to the band 2 inner edge at 0 µm for this analysis. Note that these profiles average over many photoreceptors both within and across subjects. (A) Peak-normalized band 2 intensity, color coded by eccentricity (inset) with respect to the foveal center (“x”), shows a shoulder, denoted as 2b, that grows with eccentricity. (B) Averaged eccentricity-wise image of the band 2 reflectivity. Starting in the perifovea, the 2b shoulder extends more prominently outer to the 2a peak. (C) Band 2 full width at 15% of the maximum (inset) versus eccentricity shows corresponding broadening starting in the perifovea. Note that the fovea was excluded from this analysis to focus on rod-related effects.
