  1. N = total number of patients in the study arm, n = number of patients in the group with valid data (only shown when there is invalid or missing data); At 12 weeks, median BCVA in children with severe amblyopia in the standard advice group improved by 0.27, in the Eye Five group by 0.26 logMar and in the Nintendo group by 0.26 logMar. In children with moderate amblyopia, median BCVA improved by 0.08, 0.2 and 0.26 logMar, respectively. Change in stereoacuity was small, if any
