What is nystagmus?

• A. Involuntary eye movement
• B. Involuntary jerking of the eyes
• C. Uncontrolled blinking of the eyes
• D. Blurred vision during movement

Answer: (B)

Nystagmus is characterized by involuntary jerking movements of the eyes, which can occur horizontally, vertically, or in a circular pattern. This condition can be physiological, arising naturally in certain situations (such as when the head is turned) or pathological, resulting from various medical conditions or neurological issues. The definition that emphasizes the jerking nature captures the essence of nystagmus, as it reflects the specific type of movement that defines the condition. Understanding nystagmus is important in various fields, including traffic safety, as it can be a sign of impairment, such as from alcohol consumption or certain medical conditions.
