What does nystagmus refer to?

Nystagmus specifically refers to the condition characterized by involuntary rapid movements of the eyes. These movements can be horizontal, vertical, or rotary and may occur in one or both eyes. It can be a physiological response or indicative of underlying neurological or vestibular issues. Understanding nystagmus is crucial in various medical fields, particularly in neurology and ophthalmology, as it can inform clinicians about potential disorders affecting the nervous system or balance.
