Cerebral Vision Impairment (CVI) has emerged to be one of the most prominent causes of vision impairment in children in the developed world. The spectrum of CVI creates anomalies in the quality of vision seen in conjunction with cognitive visual dysfunction. The severity of this heterogeneous condition is highly dependent on the time of onset, aetiology and areas of insult to the brain.
There is mounting empirical evidence to support strong correlations between aberrations in visual function (such as visual acuity, visual field and ocular movements) in CVI and the primary visual pathway. Additionally, research indicates that impairment of visual perception noted in CVI is closely related to abnormalities of the cortical and subcortical areas of the brain related to the secondary visual pathways.
Early identification in determining how children with CVI use their vision is critical for their development. CVI is multifaceted and unique to the individual. Therefore, it is essential for therapists working with children who have CVI to understand what aspects of visual function are affected and how they can tailor their program to optimise the child’s functional vision. This presentation will explore the common characteristics of visual function displayed by children with CVI. The discussion will highlight the impact of uncorrected refractive error, colour preference and visual field loss on functional vision.
