Correlation between CD and retinal signal strength is reduced by the rb-BMS algorithm on 24 macular (A, B) and disc (C, D) scans of healthy subjects acquired by the Cirrus/AngioPlex instrument. In macular scans, correlation between CD and signal strength changed from R = 0.58, P < 0.01 in the original image without BMS (A), to R = −0.36, P = 0.08 in the image processed by rb-BMS (B). FAZ and large vessels are excluded. On disc scans, the correlation changed from R = 0.52, P = 0.01 in the original image without BMS (C) to R = 0.36, P = 0.09 in the image processed by rb-BMS (F). Analytic zone is 4 × 4 mm, excluding the large vessels and a circle of 2-mm diameter centered at the disc.
