Electroretinography and visual evoked responses in paediatric practice
Insights
Electroretinography and visual evoked responses offer objective, non-invasive assessments for children. These tests help distinguish between retinal issues and neurological problems affecting vision.
Area of Science:
- Ophthalmology
- Neurology
- Paediatrics
Background:
- Electroretinography and visual evoked responses are valuable ancillary investigations.
- These non-invasive techniques provide objective results, requiring no patient cooperation.
- They are particularly useful in clinical ophthalmology, paediatric neurology, and developmental paediatrics.
Purpose of the Study:
- To evaluate the utility of electroretinography and visual evoked responses in a paediatric population.
- To assess the diagnostic value of these techniques for various neurological and ophthalmological conditions in children.
- To report findings from a study conducted using locally available apparatus in South Africa.
Main Methods:
- Examined 159 children using a system constructed from apparatus available in South Africa.
- Utilized electroretinography and visual evoked response recordings.
- Investigated children with indications including developmental delay, acute intracranial disease, eye disease, and cerebral degenerative disorders.
Main Results:
- The investigations provided objective data without requiring patient cooperation.
- Information obtained allowed for differentiation between retinal dysfunction and lesions in optic pathways.
- Distinctions were also made between lesions affecting the occipital cortex and higher cortical centres.
Conclusions:
- Electroretinography and visual evoked responses are effective, non-invasive tools for paediatric assessment.
- These techniques aid in diagnosing the location and nature of visual pathway disorders.
- The study demonstrates the practical application of these methods in diverse paediatric neurological and ophthalmological cases.
Abstract:
Electroretinography an the recording of visual evoked responses are of considerable value as ancillary investigations in clinical ophthalmology, paediatric neurology an developmental paediatrics. The techniques used are non-invasive and yield objective results without any need for patient co-operation. In this study 159 children were examined using a system constructed from apparatus available in South Africa. Indications for the investigations included developmental delay, acute intracranial disease, eye disease and cerebral degenerative disorders. Information obtained made possible distinctions between retinal dysfunction and lesions of optic pathways, the occipital cortex and higher cortical centres.
