Are saccadic eye movements normal?
Saccades are the fastest eye movements (up to about 500 degrees per second) and they are very brief in duration (typically less then 100 msec) . We will review the anatomy, basic clinical features and examination of normal saccades, and then review movement disorders in which saccadic abnormalities aid in diagnosis.
