What term refers to involuntary rapid eye movements?

• A. Nystagmus
• B. Occlusion
• C. Papule
• D. Petechia

Answer: (A)

Involuntary rapid eye movements are called nystagmus. It describes rhythmic, repeated eye motions that a person cannot consciously control. These movements can be horizontal, vertical, circular, or a mix, and they may appear in normal reflex situations (like after spinning) or signal underlying issues with the vestibular system, brain, or the effects of drugs. The other terms refer to different things: occlusion means blockage, papule is a small raised skin lesion, and petechia are tiny red or purple spots from minor bleeding under the skin. So, nystagmus is the specific term that namingly describes these involuntary eye movements.
