Cortical visual impairment (CVI) is a condition that affects the brain’s ability to process visual information, even though there may be no problem with the eyes themselves. It is the leading cause of visual impairment in children in developed countries.
Symptoms:
- Variable Vision: Individuals with CVI may have fluctuating vision, where their visual abilities can change from day to day or even within the same day.
- Difficulty with Visual Complexity: They may struggle with processing complex visual scenes or environments.
- Preference for Certain Colours or Patterns: Some individuals with CVI may show a preference for specific colours or patterns.
Diagnosis:
- Medical Evaluation: A thorough medical examination is necessary to rule out any eye-related issues.
- Neurological Assessment: Since CVI is a result of brain damage or dysfunction, a neurological assessment is crucial to diagnose the condition.
- Functional Vision Assessment: This involves evaluating how well an individual uses their vision in different situations.
Treatment:
- Vision Stimulation: Visual activities and exercises may be used to stimulate and improve visual processing.
- Adaptations: Modifying the environment to reduce visual complexity can be helpful.
- Multi-disciplinary Approach: Collaboration with various professionals such as occupational therapists, physical therapists, and educators is often necessary.
Help and Support:
- Educational Support: Children with CVI may benefit from personal learning plan tailored to their needs.
- Support Groups: Connecting with others who have experience with CVI can provide emotional support and practical advice.
- Assistive Technology: Depending on the severity of the impairment, there are various assistive technologies available to help individuals with CVI.
It’s essential to consult with healthcare professionals, such as neurologists, ophthalmologists, and educators, to create a comprehensive plan for managing and supporting individuals with CVI. Early intervention and ongoing support are crucial for maximising visual potential and overall well-being.
