    Electronystagmography

    The electronystagmography is based on the fact that there exists around the eye an electric field. The modifications induced in this electric field by eye movements are recorded by electrodes, filtered, amplified and analysed. Ideas III is the essential tool to study the various functions of balance, namely the study of the oculomotricity (ocular saccades, pursuit, optocinetic nystagmus) and the study of the vestibular system (spontaneous and positional nystagmi, rotatory tests, caloric tests). Ideas III is complementary with videonystagmography in case of the use of corrector optical is necessary. Moreover, the signal is not disturbed by the make-up on the eyelids or the nervous twitches.

    Disoft II

    Ideas III is accompanied by a powerful data-processing software which simplifies the task of the doctor. According to the performed tests, the software analyses and measures various parameters:

    • number of jolts or ocular movements

    • amplitude, frequency

    • low phase velocity of the nystagmus

    • latency, phase, distorsion

    • gain

    • symmetry or asymmetry of the response

    • labyrinthine paresis or hypoexcitabilities, directional preponderance of nystagmus

    • compare the answers opened eyes, closed eyes and measure the indices of ocular fixation
