The ERG was developed to assist responders that may be first to arrive at the scene of a transportation incident involving hazardous materials. mfERG responses are recorded under light-adapted conditions from the cone-pathway. (2013). It is important that there is no net change in luminance during the dark-to-light transition of the checks (i.e. Topical anesthesia is used for contact lens electrodes, but may not be necessary for DTL electrodes.
