A and B illustrate fixed-luminance electroretinography (ERG) on Diopsys, which is equal to 30-Hz flicker conventional ERG. Waves have normal magnitude (amplitude) and phase (implicit time) in both eyes. Graphs show rays (blue lines) in the green area, which indicates a normal pattern. C and D show multifocal ERG of the right and left eyes, respectively. Multifocal ERG in both eyes is normal.
