Central visual field contributions to the visual-evoked response

J R Vance, R Jones

    American Journal of Optometry and Physiological Optics
    |April 1, 1980
    PubMed
    Summary

    Visual evoked responses (VER) can identify foveal projection function even when vision is obscured. This electrophysiological method offers a clinical test for visual cortex integrity when conventional eye exams are not possible.

    Area of Science:

    • Neuroscience
    • Ophthalmology
    • Electrophysiology

    Background:

    • Visual evoked responses (VER) are electrophysiological measures of the visual pathway's function.
    • Assessing foveal projection is crucial for diagnosing visual pathway disorders.
    • Opaque media can hinder standard ophthalmological examinations.

    Purpose of the Study:

    • To investigate the utility of VER in assessing foveal projection.
    • To determine if VER can be used clinically when conventional tests are not feasible.

    Main Methods:

    • VERs were recorded using bipolar electrodes placed across the occipital region.
    • Apertures were employed to selectively block foveal stimulation.
    • The transverse distribution of the C2 component of the VER was analyzed.

    Main Results:

    • The transverse distribution of the C2 VER component indicated a radial dipole source.
    • This finding is consistent with a foveal origin within the visual cortex.
    • VER demonstrated potential for evaluating foveal projection.

    Conclusions:

    • VER analysis, specifically the C2 component, can reflect foveal origin in the visual cortex.
    • This electrophysiological technique offers a viable clinical test for foveal projection integrity.
    • VER provides a valuable diagnostic tool when opaque media prevent standard visual assessments.
