Optic flow induced nystagmus
Abstract
A new form of nystagmus is described in this paper: optic flow induced nystagmus (OFN). Optic field flow, for example when driving or viewing films on a large screen, triggered non-fatiguable upbeat nystagmus. This type of nystagmus could not be induced by vestibular stimuli, positioning, or self motion. The aetiology and anatomical correlate of OFN remains unknown. Treatment with gabapentin suppressed OFN.
