FLICKER‐ELECTRORETINOGRAPHY

Acta Ophthalmologica, 1972
Flicker ERGs from normal human eyes are recorded using an averaging technique. After 300 msec the curve is in a stationary phase with strict periodicity. It is constructed by algebraic summation of individual flash responses with “head‐to‐tail” overlapping in higher frequencies. At a flash frequency of 25 cps.

Electroretinography

The electroretinogram (ERG) is used to measure electrical activity of various cell types in several layers of the retina, including rods, cones, inner retinal cells, and ganglion, in response to a light stimulus. ERG therefore provides objective information about visual system function and can provide diagnostic information for inherited and acquired ...

Electroretinography in rats

Agents and Actions, 1988
Basic mechanisms of the rat ERG were reinvestigated with contemporary methods of recording and photic stimulation via an optic fiber system connected with a contact lens. Flash stimulation and background illuminance were performed with photometrically defined light stimuli.

Electroretinography

2018
The electroretinogram (ERG) is a mass electrical response from the retina, evoked by a brief flash of light. ERG recording is done using an active electrode (a contact lens in contact with bulbar conjunctiva) and a reference electrode (at the outer canthus); the active electrode can also be a gold foil electrode or HK-loop electrode.

Electrode Equipment for Electroretinography

Biomedical Engineering, 2011
Electrode equipment and its use in electroretinography (ERG) are discussed. Relative ERG error for corneal electrodes was 54%. Commercially available ERG electrodes can be used in medicine. The results obtained in this work provide a basis for normative documents for corneal electrodes in clinics.

Electroretinography

Acta Ophthalmologica, 2008
Abstract Purpose To illustrate the value of electroretinography in clinical practice. Methods A case presentation format will be used to illustrate how pattern electroretinography, full‐field flash electroretinography and multifocal electroretinography can be used in clinical practice.
