Three-dimensional video-oculography in patients

Abstract
Conclusions: The nystagmus recorded without visual fixation contained all three components in most patients with vestibular
neuritis (VN).
The nystagmus was unidirectional, strongly visually suppressed with the loss of vertical component in most
patients, and it obeyed Alexander’s law.
Video-oculography (VOG) is a non-invasive tool for detailed analysis of nystagmus,
and hence may improve differential diagnostics in dizzy patients.
Objective: To characterize three-dimensional nystagmus
findings in patients with acute VN using the VOG technique.
Patients and methods: A prospective study in 16 patients with
VN was carried out in a tertiary referral centre.
Nystagmus was measured on average 3 days after the beginning of
symptoms.
