Paradoxical robust visual evoked potentials in young patients with cortical blindness.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
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 (<1% of records reviewed) had clinically compromised vision with fair to good levels of visual function using VEPs. The commonality among the cases was the presence of suspected cortical visual impairment with seizures and developmental delay. VEP acuity cannot be correlated unequivocally with visually guided behaviour. In specific cases, particularly cases with developmental delay and neuroradiographic abnormalities, a child who is behaviorally blind with no clinical evidence of vision may show robust VEPs even to small patterns. This finding might be consistent with a defect of the visual association cortex.
