Insights
Cerebral visual impairment (CVI) is rising in children due to improved neonatal survival. Early ophthalmology diagnosis and intervention are crucial for improving CVI children's quality of life.
Area of Science:
- Ophthalmology
- Neonatal Medicine
- Pediatrics
Background:
- Improved survival rates for high-risk neonates have led to an increased incidence of cerebral visual impairment (CVI).
- CVI is a leading cause of childhood visual impairment in developed nations, presenting with diverse visual abnormalities.
- Children with CVI often exhibit sensory, cognitive, and motor deficits beyond visual impairment.
Purpose of the Study:
- To review recent advancements in ophthalmology diagnosis and treatment for pediatric CVI.
- To emphasize the importance of early recognition and individualized intervention strategies.
- To support pediatricians and rehabilitation physicians in enhancing the quality of life for children with CVI.
Main Methods:
- Literature review focusing on ophthalmology perspectives.
- Analysis of recent progress in CVI diagnosis and treatment.
- Synthesis of information relevant to multidisciplinary care.
Main Results:
- CVI presents complex challenges including early onset, varied etiology, and diagnostic difficulties.
- Multidisciplinary approaches involving ophthalmology, pediatrics, and rehabilitation are essential.
- Current domestic research on CVI remains limited.
Conclusions:
- Enhanced ophthalmological understanding is vital for effective CVI management.
- Early and individualized interventions can significantly improve outcomes for children with CVI.
- Collaboration among specialists is key to improving survival skills and quality of life.
Abstract:
With the rapid development of global perinatal medicine and neonatal medicine, the survival rate of high-risk neonates (premature, and those who suffer neurologic lesion during or shortly after birth, et al.) improved significantly, however the incidence of cerebral visual impairment (CVI) also rose, which has become the most common cause of visual impairment in children in developed countries. Studies found that visual abnormalities of patients with CVI can be various. Since children's cognition and motor development are inseparable from visual functions, children with CVI are usually characterized by abnormalities in sensory perception, cognition and even movement, other than visual impairment itself. Due to the characteristics of CVI, such as early onset, complex etiology, difficulty in diagnosis and treatment, and involvement with ophthalmology, pediatrics, rehabilitation medicine, genetic epidemiology and other multi-disciplinary content, current domestic research on CVI is limited. From the perspective of ophthalmologist, this paper reviews the progress of ophthalmology diagnosis and treatment in children with CVI in recent years, aiming to have better early recognition and individualized intervention, so as to help pediatrician and rehabilitation physicians to improve survival skills for CVI children and their quality of life.

Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
