Zusammenfassung: | The invention relates to a device for the photoelectric measurement and recording of arbitrary and non-arbitrary eye movements by diffuse irradiation of the eye with IR light. It is especially applied in the medical field for investigation of the vestibular system and eye mobility and for determining the line of fixation. The object of the invention is to provide a nystagmograph by using the conventional spectacle shape with free vision and with the exclusion of influences of external light, which requires minimum optomechanical outlay, is lightweight and provides high accuracy of measurement. The object to be achieved is to provide an improved overall arrangement of the measurement device, especially of the emitter and receiver elements. This is achieved in that the emitter and receiver elements present in the form of chips are arranged on one or both lenses as a circular ring or in a star shape around the optical axis of the eye and are electrically coupled to the evaluation electronics via applied strip conductors and connecting blocks. Free vision is unimpaired due to the arrangement of the chips in the region out of focus. |
