Multifocal electroretinogram (1)

Full-field electroretinogram (ERG) is not sensitive for detection of local change of retinal function because of the mass response from the entire retina. Full-field ERG abnormalities are seen with advanced or extensive disease. Multifocal ERG tests locally with focal stimulation using stimulus patterns 61-241 hexagons.
