Images from PDR and NPDR patients A-F images from a 60-year-old man with PDR without DME. A & B En face OCT slab of MLCs and binarized image. The distribution of MLCs was uneven. Some of them gathered around retinal vessels (red ellipse). C & D OCTA images of DCP and SCP. Microaneurysms and small pieces of nonperfusion area are visible. E & F B-scans and magnified images of yellow and pink lines in A. The arrows in E & F correspond to arrows of the same color in A. MLCs appeared as small protrusions located at the VRI on B scans. G-L images from a 63-year-old man with NPDR without DME. G & H En face OCT slab of MLCs and binarized image. MLCs gathered in fovea area. I & J OCTA images of DCP and SCP. K & L B-scans and magnified images of red and blue lines in G. The arrows in K & L correspond to arrows of the same color in G. MLCs appeared as small protrusions located at the VRI on B scans (arrows). Connections appear among some adjacent MLCs (blue triangle)
