Fixation indices and MDs. Scatter plots and regression lines for the three fixation indices (log-BCEA, log-MED and log-SED) showing the relationship with the global MD value. Normal subjects are in green while glaucoma subjects are in red. The shaded region represents the 95% confidence interval of the estimate. The regression estimate was obtained from a multivariate model accounting for the age of the subject and the depicted line has been calculated at the mean age of the sample (57.4 years). The scale on the right vertical axis represents the values of the log transformed measures, while the left vertical axis reports the corresponding values in the linear scale
