Figure 1

Original images and the heat maps generated by VeriSee DR of 4 cases of proliferative diabetic retinopathy (PDR) or severe nonproliferative diabetic retinopathy (NPDR) that were diagnosed as nonreferable DR by VeriSee DR. (a) A case of psedumed PDR with only suspected laser scars but no microaneurysm or hemorrhage, (b) a case of presumed PDR with atypical neovascularization of the disc and few microaneurysms, (c) a case of branch retinal vein occlusion which was diagnosed as severe NPDR, and (d) a case of age-related macular degeneration and old retinal vein occlusion which was diagnosed as severe NPDR.
