Paradoxical robust visual evoked potentials in young patients with cortical blindness

The objective of this study was to review retrospectively cases of clinically blind children in whom robust pattern visual evoked potentials (VEPs) were recorded. VEP records from a 10-year period (1990–2000) were reviewed. We searched for charts of children who were clinically cortically blind, but in whom assessment of visual acuity, using visual evoked potentials (VEPs), was normal or close to normal. The majority (77.5%) of VEP and behavioral acuity measures were concordant (subset analysis). Of the 1,113 VEP records, 9 cases (
