Acquired nystagmus can be caused by a disease (multiple sclerosis, brain tumor, diabetic neuropathy), an accident (head injury), or a neurological problem (side effect of a medication). Hyperventilation, a flashing light in front of one eye, nicotine and even vibrations have been known to cause nystagmus in rare cases.
A jerk nystagmus is usually due to a motor defect that may be induced by brainstem or cerebellar lesions, drug intoxication (upbeat nystagmus in which the fast phase is in the upward direction or downbeat nystagmus in which the fast phase is downward); associated with a lesion of the central nervous system or the vestibular nerve or nuclei (central nystagmus and vestibular nystagmus); or to disease or injury to the labyrinth (labyrinth nystagmus); or to multiple sclerosis.
