Behavioural Features of Cerebral Visual Impairment Are Common in Children With Down Syndrome

It is widely recognised that children with Down syndrome have a broad range and high prevalence of visual deficits it has been suggested those are more likely to exhibit perception indicative cerebral impairment. This exploratory study aims determine the behavioural features suggestive impairment (CVI) occurring whether problems can be ascribed optometric factors. A cohort 226 families (trisomy 21), aged 4–17, were invited participate in validated question inventory, recognise issues. The clinical records participants then reviewed retrospectively. five-question screening instrument was used indicate suspected CVI. majority 81 who responded questionnaire reported some level perceptual difficulty their child. Among this cohort, CVI as indicated by 38%. Only ametropia found significant association CVI, although increased correct prediction outcome only small amount. Results suggest experience consistent impairment, these may originate from similar brain dysfunction which contributes levels failure emmetropise. important syndrome, further investigations initiated appropriate management applied.
