BACKGROUND: Multifocal electroretinography allows simultaneous recording of 61 focal electroretinographic signals from the retina of the posterior pole. The function of the outer retinal layers can be mapped for a visual field of 30.5 degrees radius. We herein describe the topography of such potentials in @entity1 with @entity227 . SUBJECTS AND METHODS: Six @entity1 with @entity227 caused by chorioretinal and central visual pathways diseases were examined using multifocal ERG. RESULTS: In 30 normal volunteers in the entire 30 degrees visual field clear signals were obtained. In the @entity1 with @entity227 caused by @entity989 in areas with reduced light sensitivity diminished electroretinographical activity was found. In contrast, in @entity1 with @entity1805 due to a chiasmal lesion no correlation between visual field and magnitude of focal ERGs was seen. CONCLUSIONS: In @entity989 defects in multifocal ERG presented the similar pattern as scotomata in perimetry. The @entity1 with @entity227 due to disturbances in the chiasma exhibited a normal ERG-topography. In @entity1 with @entity227 multifocal ERG supported differentiation of the location of the lesion.
