Analysis of the macular region by using Heidelberg Spectralis spectral-domain optical coherence tomography. The macula is subdivided into 3 concentric circles. The central region is a circle with a 1-mm diameter centered on the fovea. The pericentral region around the central region has a 3-mm diameter centered on the fovea. The peripheral region around the pericentral and central regions has a 6-mm diameter centered on the fovea
