What is nystagmus?

Nystagmus refers to the involuntary movement of the eyes, typically characterized by a back-and-forth motion. This condition can result from various underlying issues, including neurological disorders, medications, or vestibular problems affecting balance and spatial orientation. In essence, nystagmus often indicates that the brain is receiving conflicting signals about movement and balance, leading to these involuntary eye movements. It can be observed both as a symptom of an underlying condition and as a finding during a neurological examination. Understanding nystagmus is important in fields such as medicine and safety practices, as it can impact a person's ability to safely engage in activities requiring clear vision and coordination.
