multifocal electroretinography


Also found in: Acronyms.

electroretinography, multifocal (mfERG)

Simultaneous recording of the electroretinogram from small retinal areas (e.g. 103 hexagonal areas in the central 50 degrees of the retina) which are independently light stimulated according to a binary m-sequence (e.g. a random reversal at 75 Hz). This method enables evaluation of specific regions of the retina (e.g. macular degeneration) and mainly of the cone pathway.
