Abstract

A 55-year-old woman reported blurred vision while walking, numbness and tingling, contact allodynia, and gait imbalance. Visual acuity was 20/20 in both eyes, but there was a loss of 4 lines with horizontal dynamic visual acuity testing. Ocular motility examination demonstrated spontaneous downbeat nystagmus that increased in lateral gaze with a torsional component and impaired smooth pursuits. Head impulse test was positive, and electromyography demonstrated a sensory neuropathy/neuronopathy. Vestibular testing confirmed both central ocular motor pathway and bilateral peripheral vestibular system involvement. The constellation of clinical findings and paraclinical testing was consistent with a recently recognized neurodegenerative disorder termed cerebellar ataxia with neuropathy and vestibular areflexia syndrome.
