a Multifocal ERG traces from the right eye showing normal amplitudes throughout macula. b Response density surface plot of the right eye mfERG showing normal peak at fovea and symmetric amplitude decrease with increasing eccentricity from the fovea. c mfERG traces from the left eye showing a depression in the superior field (inferior retina). d Response density surface of the left eye mfERG illustrating the relatively preserved foveal response with marked loss of amplitude in the superior field (patient 3)
