The ERG attains peak amplitude in adolescence and slowly declines in amplitude throughout life (Weleber, 1981). After age 55-60 years the amplitude of the ERG declines even more. A normal ERG shows an a-wave (photoreceptor activity) and b-wave (Muller and bipolar cells activity) patterns in dark-adapted (scotopic) and light-adapted (photopic) settings. Wave patterns that are diminished in size or delayed or prolonged in time provide clues about the types of damaged cells. What do abnormal ERG results mean? The a-wave can be normal or near-normal in an XLRS patient, whereas it may also be reduced due to the progressive atrophy of the retinal pigment epithelium. 107 The severity of ERG abnormalities does not appear to correlate with the mutation type.
