Oct 9, 2022 · The multifocal electroretinogram (mfERG) is a more recent advancement in electroretinographic testing, which enables a rapid assessment of retinal function from many areas simultaneously. Using a contrast-reversing stimulus. There are standard protocols for eliciting the retinal electrical response.

The electroretinogram (ERG) is a diagnostic test that measures the electrical activity of the retina in response to a light stimulus. The ERG arises from currents generated directly by retinal neurons in combination with contributions from retinal glia.

Dec 15, 2004 · Multifocal electroretinography (mfERG) is most useful in solving the common puzzle of a patient with poor vision who has a normal appearing retina. This test helps us discriminate between optic-nerve and retinal disease, detect early hydroxychloroquine toxicity, diagnose and distinguish between the various white dot syndromes and follow ...

Full-field electroretinography is a well-estab-lished clinical technique for evaluating global retinal function [1]. The multifocal ERG (mfERG) technique was developed to provide a topographic measure of retinal electrophysiological activity.

What is Multifocal ERG? A specialized form of pattern ERG is the multifocal ERG (mfERG) which allows for a different spatial understanding of abnormalities in the central part of the retina.

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 ISCE …

The clinical multifocal electroretinogram (mfERG) is an electrophysiological test of local retinal function. With this technique, many local ERG responses are recorded quasi-simultaneously from the cone-driven retina under light-adapted conditions. ...

Multifocal electroretinogram (mfERG) is an electroretinogram (ERG) technique that uses a particular pattern (hexagon) stimulation in unique on and off sequences (m-sequence) to stimulate localized electrical retinal responses. [1, 2, 3, 4, 5, 6] The mfERG allows simultaneous measurement of the retinal response from each section of the retina.

The multifocal electroretinogram (mfERG) technique allows local ERG responses to be recorded simultaneously from many regions of the retina. As in the case of the full-field ERG, the ganglion cells contribute relatively little to the response, which originates largely from the outer retina.

Multifocal Electroretinography (mfERG): The multifocal ERG, are used in the diagnosis of ophthalmological diseases. The mfERG is a technique for assessing the local ERG from different regions of the retina. For the routine mfERG, the retina is stimulated with a pattern of hexagons.
