Choroidal Vascularity Index as a Biomarker for Visual Response to Antivascular Endothelial Growth Factor Treatment in Diabetic Macular Edema
Figure 1
The morphological features evaluated in optical coherence tomography: (a) choroidal vascularity index (CVI); (b) subfoveal choroidal thickness (SFCT); (c) adjusted ellipsoid zone and external limiting membrane reflectivity; hyperreflective foci (HRF) (white arrow); (d) disorganization of the retinal inner layers (DRIL); (e) disruption of the ellipsoid zone; (f) disruption of the external limiting membrane; (g) the presence of subretinal fluid (SRF) (yellow arrow) and cystoid abnormalities (white arrow); (h) presence of an epiretinal membrane.
