Electro-optical device for measuring the severity of hepatic encephalopathy

摘要

The present invention is a test device in the form of a pair of spectacles, comprising a variable headband with a lens system and an observation optics having a source of stimulating light pulses, wherein the source of stimulating light pulses can emit light of several mutually different wavelengths. As a result, it is possible without further effort to adapt the wavelength of the stimulus light to the requirements of a patient, for example, if there is visual impairment or even blindness in a wavelength range. The device can be easily adapted for later measurements on normal-sighted patients turn to the local requirements.
