CVI prevalence studied

The prevalence of Cerebral Visual Impairment (CVI) may have been shown to be higher than once thought by researchers at the University of Bristol.

The study’s authors argued that many children with CVI were not identified by visual acuity tests as those with the condition have normal or near-normal acuity.

Researchers invited 262 primary school pupils for a detailed visual assessment that could identify those with brain-related problems suggestive of CVI and found that, on average, in each class of 30 children one child had at least one brain-related visual problem.

The research also showed that children who were provided extra support at school were more likely to have brain-related visual problems.
