Title

"Retinal Damage with the Multifocal ERG"

Abstract

The multifocal ERG (mfERG) technique, pioneered by Erich Sutter, produces spatially localized responses from the human retina. Examples of mfERGs from patients with various retinal diseases will be presented. To improve our understanding of the cellular contributions to the human mfERG, we turned to the monkey. In Laura Frishman's laboratory, mfERGs were recorded from monkeys before and after pharmacological agents (e.g. TTX, APB, PDA). Based upon these results, the human mfERG can be understood as a combination of receptor, bipolar and inner retinal influences. These results will be compared to those from the patients with retinal diseases.
