In the present study a modified ETDRS grid (6 × 6 mm) was used overlapped to the macular retinal and choroidal thickness maps. The grid was subdivided in nine sectors: a central sector (C) within the 500 μm from the fovea; 4 inner or juxtafoveal sectors within 500–1500 μm from the fovea (iSUP, iTEM, iINF, iNAS); and 4 outer or extrafoveal sectors within 1500–3000 μm from the fovea (oSUP, oTEM, oINF, oNAS)
