摘要
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.
