Macular and peripapillary partitioning and stratification methods. a The right eye macular is segmented for the ETDRS segmentation network. The peripheral ring and pericentral ring are divided into four quadrants: S, I, N and T. The red and green lines are reference auxiliary lines. b Segmenting the left eye macular for the ETDRS segmentation network. c The right eye peripapillary region is segmented for the ONH segmentation network, and the surrounding area of the peripapillary region is divided into eight sectors: NS, NI, IN, IT, TI, TS, ST and SN. d Segmenting the left eye optic disc for the ONH segmentation network. e The macular is divided into superficial and deep layers: SVC: superficial vascular complex; DVC: deep vascular complex. f The peripapillary layer is divided into superficial and deep layers
