Which condition is paralysis of the eye that may cause double vision?

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

Answer: (B)

Paralysis of the eye muscles can make the eyes misalign, leading to double vision. The term for weakness or paralysis of the extraocular muscles is ophthalmoplegia, which directly fits the description of paralysis that can cause diplopia. An analgesic is a pain-relieving drug and does not describe eye muscle paralysis. Hemianopia is a loss of half the visual field, not an issue with eye muscle movement. Nystagmus is involuntary, rhythmic eye movement, which can blur vision but isn’t a paralysis of the eye muscles.
