The imwaveplicit time of the a-wave is measured from the time of the flash to the trough of the a-wave. the ring ratios). Understanding how to use the ERG before an incident is key. Certain conditions including complete congenital stationary night blindness, melanoma-associated retinopathy, and juvenile X-linked retinoschisis produce a characteristic abnormality of this response that has been termed electronegative. Specifically, the a-wave has a normal (or nearly normal) amplitude, whereas the b-wave is markedly attenuated. The 70-year-old who is training for a 5-mile running race, b. Understanding how to use the ERG before an incident is key. It is optimistic and upliftning, adds spontaneity and positivity to life and it encourages social communication and creativity. Any of these folks might be the first to call emergency responders with information that could save lives. ), Figure 3. The ERG has important clinical utility, in that it provides diagnostic information concerning a variety of inherited and acquired retinal disorders. The mfERG is becoming more commonly used for both research and clinical purposes, and ISCEV provided the first standards for mfERG in 2007 (updated in 2011). (Keep in mind these should not be used in place of an actual ERG on your response vehicle). Bearse MA Jr, Ozawa GY (2014).
