Opsoclonus refers to uncontrolled eye movement. Opsoclonus consists of rapid, involuntary, multivectorial (horizontal and vertical), unpredictable, conjugate fast eye movements without intersaccadic intervals. It is also referred to as saccadomania or reflexive saccade. The movements of opsoclonus may have a very small amplitude, appearing as tiny deviations from primary position.
Possible etiologies of opsoclonus include neuroblastoma and encephalitis in children, and breast, lung, or ovarian cancer in adults. Other considerations include multiple sclerosis, toxins, or medication effects (e.g. Serotonin Syndrome. It can also be caused by a lesion in the omnipause neurons which tonically inhibit initiation of saccadic eye movement (until signaled by the superior colliculus) by blocking paramedian pontine reticular formation (PPRF) burst neurons in the midbrain. It frequently occurs along with myoclonus in opsoclonus myoclonus syndrome.

- Disorders of ocular motility due to multiple sclerosis can cause significant symptoms, such as blurred vision, diplopia, oscillopsia and dizziness. The spectrum of ocular motor disorders is broad due to the multifocal nature of the disease. The most frequent disorders include dysmetric saccades, imp
