Bold represents group means.

^†Age at surgery and maximal archived visual acuity marginally correlated negatively at r = −0.47 (P = 0.072). The N170 effect correlated with neither highest archived visual acuity nor age at surgery (see text; P > 0.3).

^‡Mean accuracy of matched controls for cc, 98.06%.

^¶Mean accuracy of matched controls for dc, 97.98%.
