The effect of light scattering on multifocal electroretinography

Ophthalmic and Physiological Optics, 2002
Purpose: Unclear ocular media is a very common condition of older eyes characterized by significant light scattering and image degradation. The multifocal electroretinography (MERG) is a useful objective technique to measure retinal activity but its ...

Effects of Smoothing and Adaptive Filtering in Multifocal Electroretinography (mfERG) [PDF]

Journal of Clinical Medicine, 2023
(1) Background: mfERG testing is used to study the function of cone photoreceptors in the central retina. Various filters including “smoothing” (Smooth) and “adaptive data filtering” (Adapt) are used to simplify raw data. This study will seek to characterize the effect of data modification on raw patient data.

The Effects of Alcohol on Visual Evoked Potential and Multifocal Electroretinography. [PDF]

J Korean Med Sci, 2016
The aim of this study was to investigate the acute effects of ethanol administration on pattern-reversal visual evoked potential (VEP) and multifocal electroretinography (mfERG). Fifteen healthy subjects with no ocular or general disease were recruited. VEP (0.25° pattern sizes) and mfERG with 19 elements in two recording segments were performed before

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.

Multifocal electroretinography in patients with Stargardt's macular dystrophy [PDF]

British Journal of Ophthalmology, 1998
To describe the topography of multifocal electroretinograms (ERGs) and to explore its diagnostic value in patients with Stargardt's macular dystrophy (SMD).51 patients with SMD were examined by means of the m-sequence technique to characterise the topography of electroretinographic responses in the central visual field.

ISCEV standard for clinical multifocal electroretinography (mfERG) (2011 edition)

Documenta Ophthalmologica, 2011
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.
