Fig. 3: Linear regression between Choroidal Vascular Index (CVI) and different ocular biometric values.
From: Macular and peripapillary Choroidal Vascularity Index in children with different refractive status

In the macular region, CVI against spherical equivalent (SE) (A), axial length (AL) (C), choroidal thickness (ChT) (E). In the peripapillary region, CVI against SE (B), AL (D), ChT (F).
