Electroretinogram

Electroretinography (ERG) is a method for studying the functional state of the retina, optic nerve and visual pathways by recording the bioelectric potentials of the cerebral cortex that arise when retinal neurons are excited under the influence of visible light. The method is based on recording biopotentials induced by weak light and allows one to obtain information about the state of photoreceptors, bipolar, retinal ganglion cells and the optic nerve. By conducting an ERG study, you can obtain an objective assessment of the functional state of the nervous tissue and the visual system as a whole, helping to identify hidden disorders at the earliest stages.
