Global Electroretinogram Incorporation of New Technology Advances The primary Global Electroretinogram waveform components analyzed include the a-wave and b-wave. The a-wave reflects the function of photoreceptor cells and is a negative deflection occurring immediately after a flash. The b-wave arises from bipolar cell activity and appears as a positive deflection following the a-wave.
