Electrophysiological tests in the assessment of visual disorders. Anales Sis San Navarra [online]. 2009, vol.32, suppl.3, pp.93-103. ISSN 1137-6627.
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 outer 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.
