Correlation between CVI, CFA, and BCVA. The postoperative a choroidal vascularity index (CVI) or b choriocapillaris flow area (CFA) were plotted along the x-axis, while the postoperative best-corrected visual acuity (BCVA) was plotted on the y-axis. The colored lines depict the linear regression of the data for either the fellow eyes or the GRT eyes. All regression lines had negative slopes, indicating that the CVI and CFA were negatively correlated with BCVA
