Fig. 2From: Postoperative choroidal vascularity index after the management of macula-off rhegmatogenous retinal detachmentNegative correlations between the CVI and postoperative BCVA. The choroidal vascularity index (CVI) and the postoperative BCVA of the surgical cases are plotted and colored according to the surgical treatment. The colored lines represent the linear regression of the data for each surgical treatment condition. The negative slope of the regression lines indicates an inverse relationship between the CVI and postoperative BCVA for both surgical groupsBack to article page
