Figure 2.

ETDRS grid with concentric circles of 1-, 3-, and 6-mm diameters overlaid on the en face image of a macula (right eye, OD) showing measurements (a) before and (b) after manual correction. The color-scaled images display a thickness map of the macula, while the adjacent grid contains the volume (red) and average thickness (black) of each macular sector. In this eye, the nasal inner and nasal outer sectors have reduced total retinal thickness and volume after manual correction of the segmentation lines.
