Research over the past 20 years has provided a clearer understanding of the pathogenesis of most forms of nystagmus and other ocular oscillations. To the clinician, these advances translate into greater accuracy of nystagmus as a diagnostic sign. However, to capitalise on these advances, it is important to systematically examine eye movements and interpret the findings with reference to pathophysiology. In this review we describe a scheme for examining the patient with nystagmus and interpreting common ocular oscillations; some examples are provided as video clips.
