    Electronystagmography

    Electronystagmography is based on the fact that an electric field exists around the eye. Changes in this electric field induced by eye movements are recorded by electrodes, filtered, amplified and analyzed. Ideas III is an indispensable tool for studying the various functions of balance, namely oculomotricity (eye saccades, eye pursuit, optokinetic nystagmus) and the vestibular system (spontaneous and positional nystagmus, rotatory tests, caloric tests). Ideas III complements videonystagmography when optical correction is required. What's more, the signal is not disturbed by eyelid make-up or nervous tics.

    Disoft II

    Ideas III is accompanied by a powerful software package that simplifies the doctor's task. Depending on the tests performed, the software analyzes and measures various parameters:

    • number of twitches or eye movements

    • amplitude, frequency

    • slow phase speed of nystagmus

    • latency, phase, distortion

    • gain

    • symmetry or asymmetry of responses

    • labyrinthine paresis or hypoexcitability, directional preponderance of nystagmus

    • compare open-eye and closed-eye responses and measure eye fixation cues
