The multifocal electroretinogram
(mfERG) is an electrophysiological test that allows
the function of multiple discrete areas of the retina to
be tested simultaneously. This document, from the
International Society for Clinical Electrophysiology
of Vision (ISCEV), presents an updated and revised
ISCEV standard for clinical mfERG and defines
minimum protocols for basic clinical mfERG recording and reporting so that responses can be recognized
and compared from different laboratories worldwide.
The major changes compared with the previous
mfERG standard relate to the minimum length of
m-sequences used for recording, reporting of results
and a change in document format, to be more
consistent with other ISCEV standards
