Nystagmus characteristics of healthy controls.

ABSTRACT:

Background

Healthy controls exhibit spontaneous and positional nystagmus which needs to be distinguished from pathological nystagmus.

Objective

Define nystagmus characteristics of healthy controls using portable video-oculography.

Methods

One-hundred and one asymptomatic community-dwelling adults were prospectively recruited. Participants answered questions regarding their audio-vestibular and headache history and were sub-categorized into migraine/non-migraine groups. Portable video-oculography was conducted in the upright, supine, left- and right-lateral positions, using miniature take-home video glasses.

Results

Upright position spontaneous nystagmus was found in 30.7% of subjects (slow-phase velocity (SPV)), mean 1.1±2.2 degrees per second (°/s) (range 0.0
