Contribution of Short-Time Occlusion of the Amblyopic Eye to a Passive Dichoptic Video Treatment for Amblyopia beyond the Critical Period

Figure 4

Contrast sensitivity improvement. (a) Contrast sensitivity of the amblyopic eye as a function of spatial frequency at baseline (solid line) and at the training outcome (dashed line) for the nonpatched group. Grey areas represent ±standard error. (b) Contrast sensitivity of the amblyopic eye as a function of spatial frequency at baseline and at the training outcome for the patched group. Same line style as (a). (c) Individual sensitivity gain of the participants at baseline, at the outcome of the training, and at the follow-up control one month later. Participants from the patched group are indicated with filled grey symbols, and participants of the nonpatched group with open black symbols.
