This device allows you to visualize eye movements. The built-in screen allows it to be used in any situation. A videonystagmoscope is equipped with a very high-sensitivity, high-resolution infrared “video” camera providing a sharp, high-quality image. This camera can be flipped from one eye to the other with a simple gesture. In addition, the examination performed can be recorded and the nystagmus observed can be archived. This 2.5 ″ LCD screen offers a very high quality image in real time, and works in parallel with the radio transmitter.
