 Electrophysiological abnormalities characteristic of eyes with AZOOR. Left eye rod specific ERG is subnormal; maximal response shows both a-wave and b-wave amplitude reduction; 30 Hz flicker ERG is markedly delayed and mildly subnormal; photopic single flash b-wave amplitude is subnormal; PERG P50 is subnormal in keeping with macular involvement. Right eye findings show no definite abnormality. The EOG light rise is markedly reduced from the left eye compared with that from the right eye.
