VIDEONYSTAGMOGRAPHY
The videonystagmography performed by a camera and infra red light measures and records the eye movement, which is analyzed by the software.NYSSTAR I is the essential tool to study the various functions of balance, namely the oculomotricity (ocular saccades, pursuit, optokinetic nystagmus) and the study of the vestibular system (spontaneous and positional nystagmi, rotary tests, caloric tests).

NYSSTAR I is able to record all eye movements, as well horizontal, as vertical and even rotary movements on option. The calibration carried out by NYSSTAR I is stable and should only be made once at the beginning of the examination.

The recording by camera removes all artefacts due to the changes of polarity between the electrodes and the skin like with the interferences of electric and electrophysiological origin.

DISOFT II
NYSSTAR I is accompanied by powerful data-processing software, which simplifies the task of the doctor. According to tests carried out, the software analyses and measures various parameters:

number of jolts or ocular movements
amplitude, frequency
slow phase speed of nystagmus
latency, phase, distortion gain
symmetry or asymmetry of the responses paresis or labyrintic hypoexitability, directional preponderance of nystagmus
measure of ocular fixation indices

THE NYSSTAR SYSTEM
NYSSTAR I is based on an USB camera. Connected to a computer, it permits to localise the centre of the pupil in real time. NYSSTAR I is provided in its case with its accessories: USB camera with 4 m cable, closed field mask, cap and USB interface.
