“…115 The retinal function after central retinal vein occlusion (CRVO) has also been evaluated using mfERG. 50,149 Kretschmann et al performed mfERG in patients with CRVO and reduced P1 amplitudes and delayed P1 implicit times were observed in both the affected and fellow eyes compared with normal controls. 149 Using wide-field mfERG (WF-mfERG), which allowed recording of mfERG responses from up to the central 90 of the retina, Dolan et al showed that mfERG abnormalities are common in both the affected and fellow eyes of CRVO patients.…”

“…Because mfERG can provide an objective measurement of central cone function, it is particularly useful in the assessment of cone dystrophy. 80,93,131,149,152,154,169,282 The main mfERG findings in patients with cone dystrophy include severe reductions in response amplitudes with delays in implicit times or complete absence of mfERG responses, especially in the central retina. 93,131,152,154,169,282 Holopigian et al evaluated both the cone-and rod-mediated mfERG in patients with cone dystrophy.…”

Abstract. Multifocal electroretinography (mfERG) is an investigation that can simultaneously measure multiple electroretinographic responses at different retinal locations by cross-correlation techniques. mfERG therefore allows topographic mapping of retinal function in the central 40--50 of the retina. The strength of mfERG lies in its ability to provide objective assessment of the central retinal function at different retinal areas within a short duration of time. Since the introduction of mfERG in 1992, mfERG has been applied in a large variety of clinical settings. This article reviews the clinical applications of mfERG based on the currently available evidence. mfERG has been found to be useful in the assessment of localized retinal dysfunction caused by various acquired or hereditary retinal disorders. The use of mfERG also enabled clinicians to objectively monitor the treatment outcomes as the changes in visual functions might not be reflected by subjective methods of assessment. By changing the stimulus, recording, and analysis parameters, investigation of specific retinal electrophysiological components can be performed topographically. Further developments and consolidations of these parameters will likely broaden the use of mfERG in the clinical setting.
