Figure 4: Full-field ERG of the left eye showed a normal rod b-wave and mixed a-wave and b-wave amplitudes. The photopic b-wave was depressed with a tendency toward a smaller photopic a-wave. The flicker ERG was also depressed but without significant delay. The dark-adapted 0.01 ERG (rod response) b-wave amplitude, 219.7 μV; dark-adapted 3.0 (rod–cone response) a-wave amplitude, -143.4 μV, and b-wave amplitude, 275.6 μV; light-adapted 3.0 ERG (cone response) a-wave amplitude, -26.9 μV, and b-wave amplitude, 56.1 μV; light-adapted 3.0 flicker (30 Hz flicker) amplitude, 46.9 μV (appearing at approximately 29 ms)
