An electroretinography (ERG) test, also known as an electroretinogram, measures the electrical response of the light-sensitive cells in your eyes. Updates made by specific organizations, including the Canadian Nuclear Safety Commission, Occupational Safety and Health Administration (OSHA), National Institute for Occupational Safety and Health (NIOSH), and United States National Fire Academy (NFA). Rapid flicker is a useful stimulus for assessing cone-pathway function, because rod photoreceptors generally cannot follow rapid flicker. Heckenlively JR, Arden G. (eds). The ERG is the ideal guide to help when responding to transportation emergencies involving hazardous materials. Some corneal electrodes contain a reference, which obviates the need for a reference to be placed elsewhere (e.g. What do the colors mean in the ERG? This response is often referred to as the mixed rod-cone response, as there are contributions from both rods and cones to the a-wave. retinitis pigmentosa, which is a genetic disease causing loss of peripheral and night vision, macular degeneration, which is a loss of vision due to the death of cells in the macula, retinoblastoma, which is a cancer of the retina, retinal separation, which is a detachment of the retina from the back of the eyeball, cone rod dystrophy (CRD), which is vision loss due to impaired cone and rod cells.
