Which condition describes involuntary rapid eye movements?

• A. Nystagmus
• B. Ophthalmoplegia
• C. Hyperopia
• D. Analgesic

Answer: (A)

Involuntary rapid eye movements are described by the term nystagmus. This condition involves rhythmic, repetitive eye jerks that can move horizontally, vertically, or circularly, and it may appear in one or both eyes. Nystagmus can occur briefly in normal situations like fatigue, but it can also indicate vestibular, neurologic, or drug-related issues. It differs from ophthalmoplegia, which is weakness or paralysis of the eye muscles leading to limited or abnormal movement rather than rapid, involuntary motion. Hyperopia is farsightedness, a refractive error where distant objects are blurred because images focus behind the retina. An analgesic is a pain-relieving medication and has no direct association with involuntary eye movements.
