Specifically, the a-wave has a normal (or nearly normal) amplitude, whereas the b-wave is markedly attenuated. The same mfERG data are displayed in three different ways. The P50 and N95 components are dependent on macular cone function, as the photoreceptors provide input into the RGCs. Headaches caused by a new eyeglass prescription are common.
