Figure 2

3.0 × 3.0 mm mode OCTA images of retinal vessel density. (a–c) SCP retinal perfusion in control patients. (d–f) SCP before, during, and after hypoglycemia in DM without DR. (g–i) SCP retinal perfusion in before, during, and after hypoglycemia in DM with DR. SCP: superficial capillary plexus; DM: diabetes mellitus; DR: diabetic retinopathy. (a) SCP: total VD 21.9%, (b) SCP: total VD 19.6%, (c) SCP: total VD 21.2%, (d) SCP: total VD 20.8%, (e) SCP: total VD 16.3%, (f) SCP: total VD 18.4%, (g) SCP: total VD 18.2%, (h) SCP: total VD 14.9%, and (i) SCP: total VD 15.4%.
