Figure 1: (a) A 1-mm2 area centered on the foveal depression was selected, and three consecutive B-scans were taken into account, in which the scan passing through the foveal center was selected as the midline scan along with one B-scan immediately above and below. (b) Optical coherence tomography (OCT) image of a patient in order to demonstrate disorganization of retinal inner layer (DRIL) measurement. (c) OCT images of the same patient showing the measurement of DRIL, which was defined as the horizontal extent of the disorganization of the boundaries between the ganglion cell-inner plexiform layer complex, inner nuclear layer, and outer plexiform layer. The normal architecture is shown by consecutive red dots, and DRIL is pointed by red line and upward red arrow
