Fig. 3.

Mean stereosensitivity and visual acuity. Mean stereosensitivity (a) and visual acuity (b) for group 1 [open circles; anodal-transcranial direct current stimulation (tDCS) followed by sham-tDCS] and group 2 (filled circles; s-tDCS followed by a-tDCS) at baseline (pre) and after 5 (post-5d) and 10 (post-10d) days of dichoptic treatment. Dashed lines represent dichoptic treatment combined with a-tDCS and solid lines represent dichoptic treatment combined with s-tDCS. *Improvement in visual acuity from baseline (p < 0.05, 2-sample paired t test). # Improvement in stereopsis from pre to post-5d in group 1 and post-5d to post-10d in group 2 (p < 0.05). Error bars represent ± within-subject SEM
