Acute Zonal Occult Outer Retinopathy with Atypical Findings
Figure 3
(a) Pattern electroretinogram (PERG) showing reduction of the P50 amplitude in the right eye. (b) Bright flash dark adapted ERGs (DA 11.0) demonstrating a “negative” ERG in the right eye, as b-wave is of a lower amplitude than a-wave. (c) Photopic single flash ERGs (LA 3.0) responses were subnormal in the right eye. (d) Light adapted 30 Hz flicker ERG (LA 30 Hz) demonstrating implicit time delay in the right eye.
