Cerebral/cortical visual impairment (CVI) is a leading cause of pediatric visual impairment in nations with developed economies and is increasing in those with developing economies. Because vision is the predominant sense used for learning, delay in diagnosis of CVI can negatively affect education, making early detection and management important. The American Academy of Pediatrics has published the policy statement "Visual System Assessment in Infants, Children, and Young Adults by Pediatricians" and an accompanying clinical report that are based on identifying potential causes of ocular visual impairment in children. Yet, routine vision screening may not accurately identify the brain-based visual impairment in children with CVI. Moreover, children with CVI often have medical complexity with other neurocognitive impairments and serious medical conditions that can make the diagnosis of CVI more difficult. Strategies are necessary for early identification of CVI to promote early diagnosis and referral for vision services that may allow a child with CVI to engage more fully in school, activities of daily living, vocational pursuits, and recreational activities. Knowledge of the characteristics of CVI as well as risk factors for CVI will assist the pediatrician in identifying children with CVI. This clinical report is complementary to previous vision screening policies, allowing both ocular and brain-based visual impairments in children to be identified and addressed. Pediatricians, other primary care physicians, pediatric ophthalmologists, neurologists, and other specialized pediatric eye care clinicians can identify children with CVI and coordinate effective evaluation, diagnosis, and referrals for vision services for these children.
脑/皮质视觉障碍(CVI)是发达经济体国家儿童视力损害的主要原因,在发展中经济体国家也在不断增加。由于视力是学习中主要使用的感官,因此 CVI 的诊断延迟会对教育产生负面影响,因此早期发现和管理很重要。美国儿科学会发布了政策声明“儿科医生对婴儿、儿童和青少年的视觉系统评估”以及一份伴随的临床报告,该报告基于识别儿童眼部视觉障碍的潜在原因。然而,常规视力筛查可能无法准确识别患有 CVI 的儿童的基于大脑的视觉障碍。此外,患有 CVI 的儿童通常存在其他神经认知障碍和严重疾病的复杂性,这使得 CVI 的诊断更加困难。需要采取策略尽早发现 CVI,以促进早期诊断和转介视力服务,这可能使患有 CVI 的儿童更充分地参与学校、日常生活、职业追求和娱乐活动。了解 CVI 的特征以及 CVI 的风险因素将有助于儿科医生识别患有 CVI 的儿童。本临床报告是对以前的视力筛查政策的补充,使儿童的眼部和基于大脑的视觉障碍都能够被识别和处理。儿科医生、其他初级保健医生、儿科眼科医生、神经科医生和其他专门的儿科眼科临床医生可以识别出患有 CVI 的儿童,并为这些儿童协调有效的评估、诊断和视力服务转介。
