Electric Retinograph Apparatus for Accurate Measurement of Visual Evoked Potentials

Designed for measuring amplitudes and latencies of electroretinograms (ERG) and visual evoked potentials (VEP) in the study of various channels of the visual system and studying the mechanisms of visual function impairment in diseases of the visual organ of various genesis, for diagnosing visual fatigue and intoxication of the body by industrial poisons, including in the zone of environmental disasters, to determine the localisation of the process in various layers of the retina, optic nerve and in the overlying parts of the visual system in the case of adverse effects in the visual system.
