  1. Column 5 reports the mean subject increase (expressed as the average of the individual means of the differences in the test results for the two eyes). All results are reported as Mean (SD). The last column reports the significance of each difference obtained from the linear models described in the Method section. Subjects are divided in patients with central scotoma (top white rows) and peripheral scotoma (bottom gray rows)
