Nystagmus Medium-wide

Medium-wide nystagmus is a type of nystagmus characterized by a moderately pronounced amplitude of eye movements.

Nystagmus is an involuntary rhythmic eye movement consisting of slow and fast phases. With medium-sweep nystagmus, the amplitude of eye oscillations is small and moderately pronounced, in contrast to small- and large-sweep nystagmus.

Medium-wide nystagmus can be observed in various diseases and lesions of the central nervous system, in particular the cerebellum and vestibular nuclei. It can be either horizontal, vertical or rotary.

Diagnosis of medium-wide nystagmus is carried out using ophthalmoscopy and electronystagmography. Treatment depends on the cause of this type of nystagmus and may include medication, physical therapy, and in some cases, surgery.

Nystagmus is a pathological deviation of the eyeball to the side. The pathology is characterized by periodic oscillatory movements of the eyeballs. The disease is most often caused by problems in either the brain or the cerebellum. One of the types of nystagmus is a medium-range change, which is characterized by the average amplitude of ocular oscillations.
