Accession:CMO:0003656 term browser browse the term
Definition:The b-wave is positive and usually larger in amplitude than the a-wave of the ERG waveform, generated by the retina in response to light. The amplitude of the b-wave is measured from the trough of the a-wave to the following peak of the b-wave. The b-wave reflects the health of the inner layers of the retina, including the ON bipolar cells and the Muller cells.
