  • Title: [Electrophysiological tests in the assessment of visual disorders].
    Author: Iragui-Madoz MI.
    Journal: An Sist Sanit Navar; 2009; 32 Suppl 3():93-103. PubMed ID: 20094089.
    Abstract:
    Some electrophysiological tests are helpful in the assessment of visual disorders. The physiological basis, technical aspects and general indications of those available at most neurophysiology services are reviewed. The Full-Field electroretinogram reflects photoreceptor and inner retinal function. The Pattern electroretinogram assesses retinal ganglion cell function and can identify macular dysfunction mimicking optic nerve disease. The electro-oculogram is a test of function of the outer retina and retinal pigment epithelium; it differentiates Best's disease from all other bestrophinopathies. Visual evoked potentials evaluate the visual pathway and are especially helpful in the evaluation of the optic nerve.
