Characterization of Higher Visual Function Deficits (HVFDs) with a Question Inventory in children with Cerebral Visual Impairment (CVI) and good visual acuity (VA)



Purpose: CVI, the commonest cause of visual loss in children in the developed world with prevalence rising worldwide; manifests with variable VA loss and diverse HVFDs such as difficulty with motion perception and visual environmental clutter. Visual behaviorisms suggestive of HVFDs even in CVI children with good VA, are oberved by parents and teachers with adverse effects on daily activities at school and home. Good VA in CVI children often precludes further investigation for HVFDs. We investigated HVFDs in children with CVI and good VA through structured history-taking with HVF Question
