Insights
Cerebral/cortical visual impairment (CVI) is a growing cause of vision loss in children. Early detection is crucial for educational and developmental success, as routine screenings may miss brain-based vision issues.
Area of Science:
- Pediatric ophthalmology
- Neuroscience
- Developmental pediatrics
Background:
- Cerebral/cortical visual impairment (CVI) is a primary cause of childhood vision impairment globally.
- Early diagnosis of CVI is critical to mitigate negative impacts on education and development.
- Standard vision screenings may not detect CVI, which originates from brain-based visual processing issues.
Purpose of the Study:
- To highlight the need for improved strategies for early identification of CVI in children.
- To complement existing pediatric vision screening policies by addressing brain-based visual impairments.
- To equip pediatricians and other clinicians with knowledge of CVI characteristics and risk factors for timely diagnosis.
Main Methods:
- Review of current pediatric vision assessment policies and clinical reports.
- Analysis of the limitations of routine vision screening in identifying CVI.
- Emphasis on the importance of understanding CVI characteristics and risk factors.
Main Results:
- Routine screenings often fail to identify CVI, a significant cause of pediatric vision impairment.
- Children with CVI frequently present with complex medical and neurocognitive conditions, complicating diagnosis.
- Pediatricians require enhanced knowledge to identify CVI and facilitate early intervention.
Conclusions:
- Improved strategies are essential for the early identification and management of CVI.
- A coordinated approach involving various medical specialists is necessary for effective CVI evaluation and referral.
- Addressing CVI early promotes better engagement in education, daily living, and vocational activities.
Abstract:
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.
