摘　　要：中枢视觉损伤(CVI)是中枢视觉通路受损,导致视功能障碍的一组症候群,最常见于缺血缺氧性脑病,是发达国家儿童视觉损伤最常见原因,在发展中国家也日见增多。CVI患儿除视功能严重受损外,还常缺少独立生存能力,家庭、社会将为此付出巨大的抚养和教育成本。本文从了解CVI常见病因和临床特征,掌握CVI基本检查方法和意义,重视CVI早评估、早发现和早干预,加强CVI宣传普及预防工作和多学科交叉合作4个方面,强调关注CVI和给予CVI患儿更多、更为有效的关爱。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.
