Add to ORKGMacrosquare-wave jerks are large eye movements, typically greater than 5 degrees, that occur at a frequency of about 23 Hz. After taking the eye off the target, they return it after a latency of about 80 milliseconds. These eye movements occur in light or darkness, and they occasionally are suppressed during monocular fixation. Macrosquare-wave jerks occur in bursts and vary in amplitude. They are encountered in disease states that disrupt cerebellar outflow, such as MS
