Higher amounts of retinal nonperfusion are seen in patients with more severe retinopathy. Increased CNP is associated with macular thickening and subsequent vision loss. Having predominantly PNP was independently associated with worse VA, regardless of macular thickness. Further studies are needed to investigate the role of PNP in vision loss in diabetic retinopathy.
