Orange: Orange is the down hill free for all of the ERG process. Present low strength flashes before stronger flashes to avoid partial light adaptation from strong flashes. They form part of the back of the eye known as the retina. The ERG has important clinical utility, in that it provides diagnostic information concerning a variety of inherited and acquired retinal disorders.

Research indicates that N1 has generators similar to those of the a-wave of the light-adapted ffERG, whereas the P1 and N2 have generators that are similar to the light-adapted b-wave and OPs. WHITE Introduction, instruction, guidance, placards, and more. It is not intended to provide information on the physical or chemical properties of dangerous goods. If you are reading a placard or label which has a four-digit number in the center, you can look up the chemical name in the yellow pages, which will tell you the name of the chemical and the Guide number.
