Insights
This study introduces a multidisciplinary assessment for children with neurological disorders at risk for cerebral visual impairments (CVI). Findings show a strong link between brain damage and functional vision, impacting daily tasks and communication.
Area of Science:
- Neurology
- Ophthalmology
- Developmental Psychology
Context:
- Children aged 0-9 years with neurological disorders are at risk for cerebral visual impairments (CVI).
- Longitudinal and prospective studies are crucial for understanding CVI progression.
- Existing assessments may not fully capture the extent of functional vision loss in CVI.
Purpose:
- To evaluate a complex, multidisciplinary medical and psychological assessment model for children at risk of CVI.
- To correlate neuroimaging and electrophysiological findings with functional vision outcomes.
- To establish a prognostic framework for CVI in pediatric populations.
Summary:
- The assessment integrates ophthalmological, psychological, and functional vision evaluations.
- Para-clinical methods include magnetic resonance imaging (MRI) and visual evoked potentials (VEP).
- A significant correlation was found between the extent of brain damage and the level of functional vision, affecting communication and task completion.
Impact:
- The proposed complex assessment model provides critical insights into CVI.
- It highlights the relationship between general developmental level, functional vision, and disease prognosis.
- This approach aids in a more comprehensive understanding and management of CVI in children.
Unlabelled:
The goal of the research is the evaluation of a complex and multidisciplinary assessment model medical and psychological, of children age 0 and 9 years old with neurological disorders with risk for cerebral visual impairments (CVI), in the frame of longitudinal and prospectively studies. The methods of complex assessment of children with CVI are the following: ophthalmological assessment; psychological assessment of general development on different area; functional vision assessment. These clinical methods are completed by para-clinical ones through magnetic resonance imaging and visual evoked potential. The results revealed the existence of a powerful and significant correlation among the level of brain damage and functional vision level involved in communication and achievement of different and concrete visual tasks.
Conclusions:
The cerebral visual impairment represents a severe degradation of vision, in spite of visual clinical behaviours, which can not explain and justify the severity of functional vision loss. But the complex assessment method proposed in the frame of this research underlined relevant information related with the general developmental level of children, the functional vision level and disease prognostic.
