An impaired or saccadic vVOR suggests that there is failure of both the pursuit and (bilateral) vestibular systems, and CANVAS should be considered, especially when neuropathy is present. [collections.lib.utah.edu]

Van Stavern, MD, Associate Professor, Ophthalmology & Visual Sciences and Neurology, Washington University School of Medicine Description A 67 year old woman presented with 1 year of progressive numbness, gait instability, and oscillopsia when walking [collections.lib.utah.edu]
Oscillopsia is the blurring and inability to focus on objects whilst moving. It manifest as the difficulty to read road signs when driving or recognize faces when walking. Oscillopsia occurs when both the vestibulo ocular reflexes (VOR) fail. [lmhofmeyr.co.za]

Treatment
There are very minimal treatment options for this rare disorder because it is not found in many patients. The treatment is symptomatic and you will need assistive devices because you have 3 impediments to balance. [hearingaidsfortlauderdale.com]

Etiology
Abstract CANVAS (cerebellar ataxia with neuropathy and vestibular areflexia syndrome) is a rare neurological syndrome of unknown etiology. The main clinical features include bilateral vestibulopathy, cerebellar ataxia and sensory neuropathy. [ncbi.nlm.nih.gov]
We measured horizontal and vertical semicircular canal function using the video-head-impulse test (vHIT) and hypothesized that specific vHIT-patterns may be linked to certain etiologies. [readbyqxmd.com]

The pathophysiology of such clinical-electrophysiological discordance remains unexplained. [jneurology.com]
There has also been extensive research into the underlying pathophysiological mechanisms, and it was recently shown that a dorsal root ganglionopathy causes the sensory impairment in CANVAS ( Szmulewicz et al., 2014 ). [academic.oup.com]
