[Paying attention to cerebral/central visual impairment].

Cerebral/central visual impairment (CVI) has a wide range of features owing to central visual pathway disorders. It is currently the most common type of visual impairment in children in developed countries and is increasing in the developing world. The major cause of CVI is hypoxic-ischemic encephalopathy in premature children. CVI occurs from the postgeniculate visual pathway to the occipital lobe and results in severe visual impairment and even blindness. CVI may also lead to visual cognitive disability, walk difficulty, delayed social interaction and autism spectrum. These children are less likely to live independently, and this will impose huge costs on families and society. Therefore, much more care and attention should be paid to CVI.
