OCTRIMA thickness maps for a diabetic patient with mild nonproliferative diabetic retinopathy without macular edema (male, 59 years old). Note that thickness maps for the total retina and the intraretinal layers are shown. We also note that an OCTRIMA macular map is divided into nine zones that correspond to the ETDRS regions: fovea within a diameter of 1 mm centered on the foveola; pericentral ring, the circular band from the central 1 to 3 mm, divided into four quadrants, i.e., superior, inferior, temporal, and nasal; and peripheral ring from 3 mm up to 6 mm, divided into the same quadrants.
