Comparison of deep retinal capillary plexus (DRCP) vessel density and ganglion cell layer plus inner plexiform layer (GCL-IPL) thickness between control group, diabetic retinopathy (DR) eyes with normal best-corrected visual acuity (BCVA) and DR eyes with decreased BCVA. The vessel density in DRCP (a) and thickness of GCL-IPL (b) are significantly lower in eyes with DR and decreased BCVA than in eyes with DR and normal BCVA
