Seemungal BM, Masaoutis P, Green DA, et al., 2011, Symptomatic Recovery in Miller Fisher Syndrome Parallels Vestibular-Perceptual and not Vestibular-Ocular Reflex Function., Front Neurol, Vol: 2
Unpleasant visual symptoms including oscillopsia and dizziness may occur when there is unexpected motion of the visual world across the subject's retina ("retinal slip") as in an acute spontaneous nystagmus or on head movement with an acute ophthalmoplegia. In contrast, subjects with chronic ocular dysmotility, e.g., congenital nystagmus or chronic progressive external ophthalmoplegia, are typically symptom free. The adaptive processes that render chronic patients asymptomatic are obscure but may include a suppression of oscillopsia perception as well as an increased tolerance to perceived oscillopsia. Such chronic asymptomatic patients display an attenuation of vestibular-mediated angular velocity perception, implying a possible contributory role in the adaptive process. In order to assess causality between symptoms, signs (i.e., eye movements), and vestibular-perceptual function, we prospectively assessed symptom ratings and ocular-motor and perceptual vestibular function, in a patient with acute but transient ophthalmoplegia due to Miller Fisher Syndrome (as a model of visuo-vestibular adaptation). The data show that perceptual measures of vestibular function display a significant attenuation as compared to ocular-motor measures during the acute, symptomatic period. Perhaps significantly, both symptomatic recovery and normalization of vestibular-perceptual function were delayed and then occurred in a parallel fashion. This is the first report showing that symptomatic recovery of visuo-vestibular symptoms is better paralleled by vestibular-perceptual testing than vestibular-ocular reflex (VOR) measures. The findings may have implications for the understanding of patients with chronic vestibular symptoms where VOR testing is often unhelpful.

Patients with chronic dizziness pose a particular challenge to the clinician, partly because their symptoms correlate poorly with standard vestibular tests; so a 'test and think later' approach is likely to lead to diagnostic confusion rather than clarity. Rather, a meticulous clinical assessment is required. Here our approach to the chronic dizzy patient is described with an emphasis on treating the patient's symptoms.
