Figure 4.

Amount of best-corrected visual acuity (BCVA) improvement for the amblyopic eye as a function of the number of hours of treatment for children randomized to play the binocular game (top) and children who were randomized to patching (bottom). There was a moderate linear relationship between hours of binocular game play and the amount of BCVA improvement observed. In the patching group, we were unable to confidently identify a relationship between hours of patching and the amount of AE BCVA improvement observed.
