Retinal thickness measurements of each of the nine subfields corresponding to the Early Treatment of Diabetic Retinopathy Study ETDRS areas were examined. ETDRS SD-OCT thickness measurements consist of nine separate regions, which are defined by three concentric rings centered on the fovea with diameters of 1, 3, and 6 mm, respectively. The observation of ORTs, using “en face” OCT, also indicates the size of these lesions inside the retina. ORT can be frequently found among AMD patients 56% of exudative and 21% of atrophic forms 3, and their incidence is probably underestimated 4.
