Electric oculographic testing instrument

A device for processing electro-oculographic signals comprises series-conted a sensor of an EOG signal, an amplifier-multiplexer, a low-pass filter, a high-pass filter, an analog-to-digital converter, a stationary disturbance detection unit, a stationary disturbance suppressing unit, a multiplier, an adder-accumulator, a digital comparator, a time gate, a memory unit, a digital discriminator, and a control unit. In addition, the device comprises a stimulation period determination unit, an extrema determination unit, a first function generator, a second function generator, a classification unit, a visual stimulator, a calibrator, and a data display unit. The control unit has a plurality of outputs connected to respective additional inputs of the aforesaid units.

Device for processing electro-oculographic signals

A method for automatic processing of electro-oculographic signals consists in carrying out visual stimulation of a patient at a preset stimulation angle and within a preset period of time, recording the signal of the bioelectric potention of the patient's eye, amplifying said bioelectric potential signal and limiting its spectrum, measuring the amplitude of the bioelectric potential signal at preselected instants of time, and subjecting the thus-measured values of the amplitude of said signals to statistical analysis to determine a constant electro-oculographic eye potential. The time instants at which the amplitude is measured are selected by determining the global extreme values of an absolute magnitude of the bioelectric potential within a preset number of stimulation cycles, comparing the modules of the thus-fixed global extreme values to one another and comparing the time intervals between the fixed global extreme values with the stimulation period.
