摘要
We investigated the effect of artificial parafoveal scotomata on the multifocal electroretinogram (M-ERG). M-ERGs were recorded from normal subjects using a monitor with several different sizes of black paper attached. A lower response density area around the 10 to 15 degree parafoveal region was not recognized for scotomata up to 3 degrees but was observed in scotomata above 5 degrees (visual angle) in the field topography of M-ERG. The shape of the scotomata was not circular but somewhat oval. The results from two cases of parafoveal retinal degeneration accorded well with this basic study.
