Cross-sectional and en face segmentation of choroidal and retinal thickness measurements obtained by SD-OCT. a The macula was divided into nine parts: the central fovea and the temporal, nasal, inferior, and superior regions of the parafovea and perifovea. The diameter of the central foveal region was 1 mm. The parafoveal region ranged from 1 to 3 mm from the central foveal region, and the perifoveal region ranged from 3 to 6 mm from the central foveal region. b The boundaries of the fundus structure were segmented by an automated algorithm, and the thickness profiles of the macular outer retinal sub-layers and choroid were determined. S, superior; N, nasal; I, inferior; T, temporal; HFL + ONL, Henle fibre layer and outer nuclear layer; GCL + IPL, ganglion cell layer and inner plexiform layer; RNFL, retinal nerve fibre layer
