Characteristic eye movements found in Opsoclonus Opsoclonus is a form of saccadic intrusion characterized by multidirectional conjugate eye movements with horizontal, vertical, and torsional directions. The saccades are rapid, involuntary, lack an intersaccadic interval, and do not follow a rhythmic pattern. Because of these characteristics, opsoclonus is also often referred to as saccadomania.
