Overall improvements in visual function. (a, b) Stereopsis and amblyopic eye visual acuity measurements averaged across all 16 participants at baseline (Pre) and after 5 (post-5d) and 10 (post-10d) treatment sessions. *Significant change from baseline (p < 0.05, 2-sample paired t test). (c) Suppression measured as the Weber contrast that could be tolerated in the fellow eye when the amblyopic eye was presented with a random dot kinematogram (RDK) stimulus at 100 % contrast. Larger values indicate weaker suppression (less contrast difference between the eyes was required to overcome suppression). Error bars represent ± within-subject SEM. (d) Correlation between baseline visual acuity and change in visual acuity after 10 sessions. Each data point represents an individual participant. The positive correlation indicates that the treatment effect was smallest for participants with mild amblyopia and largest for those with more severe amblyopia
