Neuro-ERG

Description

Objective Vision Test and Analysis of the Retinal Function

  • rod ERG
  • maximal ERG
  • cone ERG
  • pattern ERG
  • focal ERG
  • on/off ERG
  • flicker ERG
  • oscillatory potentials
  • electro-oculography (EOG)

Neuro-ERG system can be used to examine the patients of different age groups including newborns.

Neuro-ERG complies with the standards approved by the International Society for Clinical Electrophysiology of Vision (ISCEV).

Set of Specially Designed Electrodes

The set of unique ERG electrodes is supplied with the device. The electrodes were specially developed with the assistance of A.M. Shamshinova — M.D., the leading Russian specialist in vision electrophysiology, the main researcher of the Moscow Scientific Research Institute of Ophthalmic Diseases (Helmholtz).

The electrodes are constructed in the form of small “hooks” and “loops”. The electrodes of such shape do not cause unpleasant feelings in a patient during the exam and are very convenient in use for a doctor. While the “lens-sucker” electrodes which are widely used in clinics prevent the patient from concentrating on the exam because of “excessive mobility”. It results in lots of noises that affect signal quality.

Moreover, many specialists consider the use of “lens-sucker” electrodes to be improper in some exams (for example, at focal or cone ERG), as the main condition is not fulfilled, that is the test performing in the photopic conditions.

Mini Ganzfeld Stimulator

To perform the main tests (cone ERG, rod ERG, flicker ERG, oscillatory potentials), the mini Ganzfeld stimulator manufactured by Neurosoft is used. This device complies with ISCEV requirements. The compact design of the stimulator is user-friendly and ensures high-quality results.

Penlights with Concentrators

To perform such tests as focal ERG or cone ERG on color stimuli, the penlights with concentrators (red, blue, green, white) are used. They are placed on the special holder. It solves the problem of the stimulator fixation near the pupil.

Solution for a Wide Range of Clinical Tasks

ERG allows detecting the pathological process in the inner and outer layers of the retina, in its central and peripheral parts. The technique makes it possible to study the state of rod and cone systems separately.

The important application of this technique is the diagnostics of initial changes in the retina. The electroretinogram changes are common for many retinal diseases. They allow assessing the injury level.

ERG is also required to make a differential diagnosis of the retina and visual nerve. In this case, it is done together with visual evoked potentials (VEP) study. Electroretinography as other neurophysiological techniques is nosologically nonspecific. It is impossible to detect the cause of ERG change using the trace. However, the right choice of ERG recording conditions allows for solving a wide range of diagnostic tasks. It makes this study very important in ophthalmological practice.

The support of HL7 standard allows integrating all diagnostic Neurosoft systems into the information system of a healthcare facility.
