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. Theyll usually dilate your eyes with eye drops in preparation for the test. The PhNR has gained interest because it is primarily driven by retinal ganglion cells. The source of the P50 is debated, but there is some evidence suggesting that it is generated by RGCs with additional contributions from more distal sites. Example mfERG responses from a normal eye are shown below. Doc Ophthalmol 126:17. This will aid in preparing for down range mitigation operations as well as establishing Hot, Warm, and Cold Zones.
