Neuro-ERG corresponds to ISCEV standards.
Amplifier and Stimulator with Excellent Specifications
Sampling rate of “Neuro-ERG” amplifier — up to 40000 Hz per channel, A/D converter — 16 bit, bandpass — from 0.02 up to 10000 Hz. Maximal brightness of mini-ganzfeld stimulator — 1500±150 cd/m2, brightness control range — from –3 up to 0 log units. Stimulation frequency — from 0.05 up to 100 Hz. The specifications of such level allow receiving high-quality curves.
Set of Unique Electrodes
The set of unique ERG electrodes developed specially with the assistance of leading Russian specialist in vision electrophysiology, main researcher of Moscow Scientific Research Institute of Ophthalmic Diseases (Helmholtz), M.D., A.M. Shamshinova is supplied with the device.
The electrodes are constructed in the form of small “hooks” and “loops”. The electrodes of such shape do not cause the unpleasant feelings in a patient during the checkup and are very convenient for a doctor during the operation. While the “lens-sucker” electrodes which are widely used in clinics, prevent the patient from concentrating on the checkup because of “excessive mobility”. The same thing results in lots of noises, which effect the signal quality.
Moreover, many specialist consider the use of “lens-sucker” electrodes to be improper in some checkups (for example, at local ERG or cone ERG), as the main condition is not fulfilled, that is the test performing in the photopic conditions.
To perform the main tests (cone ERG, rod ERG, rhythmical ERG, oscillatory potentials), the mini-ganzfeld stimulator manufactured byNeurosoft Ltd. is used. This device does not have analogues in Russian Federation and satisfies completely ISCEV standard requirements.
The compact design of the stimulator provides the convenience for a patient during the checkup and the receiving of high-quality results.
Penlights with Concentrators
To perform such tests as local ERG or cone ERG on color stimuli, the penlights with concentrators (red, blue, green, white) are used.
They are placed on the special holder, and thus it solves the problem of the stimulators fixation near the pupil.
Simultaneous registration of reversal pattern VEP and ERG

According to safety standards all the computer equipment used with digital EEG system should be connected via isolation transformer.
