Post-operative OCT and OCTA images of control and IERM patients. A.OCT and OCTA images of a control patient (female, 53 years old), demonstrated normal reference structure of retinal, FAZ, SCP and DCP. B. OCT and OCTA images of an IERM patient (female, 65 years old) without DRIL at post-op12 months, had clear and identifiable inner retinal layer structure and a reduced area of FAZ with irregular morphology and tortuous vessel. C.OCT and OCTA images of an IERM patient (male, 61 years old) with DRIL at post-op12 months, showed inability to identify boundaries between the ganglion cell-inner plexiform layer, inner nuclear layer and outer plexiform layer and a typical ischemic appearance in both FD-300 (the area around the actual FAZ within 300 μm width marked yellow) and DCP, capillary network
