The mfERG has also been recorded in conditions such as retinitis pigmentosa, branch retinal artery occlusion, and Stargardt disease. (Courtesy of J. Jason McAnany, PhD. 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. at the begging of the ERG includes instructions on how to use the book, where to call for emergency assistance, an overview of that hazard classification system, and am explanation of placards and other warning systems. Your eyes may feel sensitive after the test. This approach produces a wealth of information and there are several ways in which the information can be condensed for display. 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.
