Contrast sensitivity at near
SD
Before the training, CS results did not show statistically significant differences between groups for any of the spatial frequencies evaluated (Binocular contrast sensitivity results (mean ± SD, and minimum–maximum) at near measured with the OPTIcTRAIN® test before and after the visual training1.02 ± 0.60(0.35–2.00)0.98 ± 0.55(0.33–2.00)1.57 ± 0.57(0.38–2.00)1.45 ± 0.55(0.60–2.00)1.61 ± 0.51(0.69–2.00)1.51 ± 0.52(0.71–2.00)1.19 ± 0.53(0.38–2.00)1.22 ± 0.62(0.15–2.00)1.00 ± 0.73(0.18–2.00)0.81 ± 0.60(0.05–2.00)0.62 ± 0.48(0.05–2.00)0.69 ± 0.53(0.15–2.00)1.08 ± 0.52(0.26–2.00)1.19 ± 0.61(0.32–2.00)1.51 ± 0.58(0.38–2.00)1.49 ± 0.54(0.60–2.00)1.51 ± 0.58(0.22–2.00)1.72 ± 0.45(1.02–2.00)1.24 ± 0.56(0.38–2.00)1.31 ± 0.56(0.38–2.00)0.87 ± 0.57(0.28–2.00)1.03 ± 0.65(0.33–2.00)0.55 ± 0.31(0.06–1.02)0.55 ± 0.39(0.14–2.00)Concerning the longitudinal analysis in each group, no statistically significant changes were detected with training in any CS value measured (placebo group: 0.5 cpd,
