From: Novel superpixel method to visualize fundus blood flow resistivity in healthy adults
Scatter plots of BOM, (A) Optic nerve head (BOM.ONH) and (B) choroid (BOM.CHD), calculated using the rubber band method and the superpixel method. These scatter plots do not include BOM.T or TCR. The blue line on each graph was fitted using univariate regression. There were good correlations between the parameters calculated using the rubber band method and superpixel method for both regions (ONH: R2 = 0.8, CHD: R2 = 0.81). (C-1) is the fundus image of the same eye. Examples of average blood flow maps and BOM maps that showed high correlation (C-1,C-2) between the rubber band method and the supperpixel method are shown in panels (C-1) and (C-2); maps with low correlation are shown in (D-1) and (D-2). The blue arrow in (C-2) indicates an artifact caused by a shadow of the eyelash present during measuring.
