    Summary

    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.
