Nystagmus and Other Ocular Oscillations (slideshow)

Nystagmus is a form of ocular oscillation in which the primary disturbance is an unwanted slow-phase drift of the eyes away from the target of interest. It contrasts with the type of disturbance of fixation in which the primary offending movement is an unwanted saccade (intrusion) away from the target of interest. Here we combine a mechanistic and observational approach to develop a flow chart for the classification of nystagmus for diagnosis and treatment.
