The multifocal pattern electroretinogram in glaucoma [PDF]
Vision Research, 2004 The pattern ERG can be used to detect early glaucomatous change, because the response of cells in the inner retina from (typically) 20 degrees -40 degrees of area is reduced before perimetric abnormality is certain. The multifocal pattern electroretinogram (mfPERG) allows analysis of many local regions within this area.

Multifocal electroretinogram in retinal vein occlusion [PDF]
Saudi Journal of Ophthalmology, 2010 To determine the effects of retinal vein occlusion (RVO) on multifocal electroretinogram (MF-ERG) parameters, to correlate MF-ERG and standard electroretinogram (ERG) and to correlate MF-ERG with findings of optical coherence tomography (OCT) in cases of RVO.Both eyes of 50 patients with RVO and 50 eyes of 25 normal subjects were examined using MF-ERG,

Multifocal electroretinogram changes in patients with retinal vein occlusion
Delta Journal of Ophthalmology, 2020 Background Retinal vein occlusion (RVO) is one of the most common vascular retinal disorders that lead to macular edema. There is often discrepancy between visual prognosis and optical coherence tomography (OCT) changes.

Multifocal Electroretinograms [PDF]
Journal of Visualized Experiments, 2011 A limitation of traditional full-field electroretinograms (ERG) for the diagnosis of retinopathy is lack of sensitivity. Generally, ERG results are normal unless more than approximately 20% of the retina is affected. In practical terms, a patient might be legally blind as a result of macular degeneration or other scotomas and still appear normal ...

Topographic mapping of retinal function with the SLO-mfERG under simultaneous control of fixation in Best's disease [PDF]
, 2003 Purpose: To introduce the scanning laser ophthalmoscope-evoked mfERG (SLO-mfERG) as a new method to measure focal retinal function. Methods: Sixty-two healthy individuals and 12 patients with Best's disease were examined.
