Figure 1

Divisions of the retinal layer using Spectralis SD−OCT. color-coded retinal thickness map showing mean thicknesses for each of nine subfields: scan area of 6 × 6 mm, divided into three concentric circles with 1 mm, 3 mm, and 6 mm diameter, respectively. Here, we used values from the 3 and 6 mm circles of the grid excluding a central area (1 mm radius) that corresponded to the foveola. SD-OCT, spectral-domain optical coherence tomography; RNFL = retinal nerve fiber layer; GCL = ganglion cell layer; IPL = inner plexiform layer; INL = inner nuclear layer; OPL = outer plexiform layer; ONL = outer nuclear layer.
