Figure 8. SDD and BlinD thicknesses and photoreceptor topography.

Lesion thicknesses in foveal sections of 20 non-neovascular AMD eyes and plotted for comparison with the spatial density (cells/ mm²) of photoreceptor inner segments along the horizontal meridian in adult human retina ²¹. In this log plot, zero densities and thicknesses are not shown. The photoreceptor mosaic is cone-dominated at ≤0.5 mm eccentricity and rod-dominated elsewhere. Both SDD and BlinD are found across the macula. However, SDD is thick and prevalent in rod-rich macular regions. BlinD is thin and prevalent in cone-rich macular regions.
