Mean values of white and blue membranes and correlation between brightness ratio (membrane/optic disc) and P1-amplitude ratio (left/right). Large symbols represent mean ± SEM for white and blue membranes and show a significant difference in P1-amplitude ratio (P = 0.027) and brightness ratio (P < 0.001). When observed together, the blue (●) and white (°) membranes show a significant correlation (r = 0. 762; P = 0.006).
