TUESDAY, Feb. 4, 2025 (HealthDay News) — Nystagmus during vertigo attacks in patients with Meniere disease can be video-recorded with a mobile phone and provide a helpful therapeutic aid, according to a study published online Dec. 12 in the Journal of Clinical Medicine.
Valéria Ionescu, from the Centre Hospitalier Universitaire de Saint Etienne in France, and colleagues describe the characteristics of nystagmus during vertigo attacks, the feasibility of self-video recording of eye movements by mobile phone, and the therapeutic implication of nystagmus. Patients with definite MD according to the Barany Society were included in the study; they were recorded during their attacks by videonystagmoscopy by the physician and/or mobile phone by the patient or immediate surroundings.
Overall, eight, eight, and one patients were video-recorded by mobile phone, videonystagmoscopy, or both, respectively. The researchers found that in 14 patients (seven irritative type, five deficit type, and two changed from deficit to irritative type), the nystagmus was horizontal. In three patients, the nystagmus was vertical (two down-beating and one up-beating); in two patients, the vertical nystagmus changed to a more classical horizontal nystagmus.
“The direction of the nystagmus during vertigo attacks in MD is mostly horizontal, although it can be vertical and can change direction,” the authors write. “From a diagnostic point of view, the direction of the nystagmus is of no value to deducing the affected side in MD. The nystagmus during vertigo attacks can be video-recorded by the mobile phone of the patient, which is objective proof of the impact on daily life and confirms a disabling MD. From a therapeutic point of view, this was a helpful aid when chemical labyrinthectomy was being considered.”
