Multifocal ERG programs measure electrical activity from more than a hundred retinal areas per eye, in a few minutes. The enhanced spatial resolution enables scotomas and retinal dysfunction to be mapped and quantified. In the protocol below, we describe the recording of mfERGs using a bipolar ...
The mfERG responses obtained from eyes with CRVO were significantly different from those derived from the fellow eye, especially when the rings are grouped as central and peripheral. mfERG is a new, safe, non-invasive, and quick investigative tool to assess retinal function. Our results suggest...
By examining the stimulus intensity response function, Kawabata and Adachi-Usami10 claimed that decreased retinal illuminance did not explain the reduced ERG response because the responses of the high-myopic eye had much lower saturated amplitudes than for the emmetropic eye. Second, the electrical ...

We used the mfPOP platform to stimulate both eyes simultaneously with 84 stimulus regions/eye while recording VEPs with 64 EEG electrodes. The mfPOP and mfVEP tests were done on the same day for every subject. The mfVEP study of AMD has been partially published20, but in that publication...

electroretinography (mfERG) with microperimetry in intermediate age-related macular degeneration (AMD).Sixty AMD participants underwent multifocal electroretinography (mfERG) and microperimetry testing in one eye, and 44 control participants were included to provide normative values for...
Treatment with immunosuppressive agents leads to an earlier, faster, and better recovery of VA, and a delayed but limited recovery of macular function as indicated by mfERG at 12 months. MfERG could be an ancillary test that may be useful in guiding therapy of patients with VKH syndrome....
