Which term means paralysis of the eye that can cause double vision?

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

Answer: (B)

Paralysis of the eye that can cause double vision is ophthalmoplegia. This term describes weakness or paralysis of the extraocular muscles that move the eye, so the eyes can’t align properly and you experience diplopia. The diplopia is usually binocular, meaning it goes away when you cover one eye. Nystagmus refers to involuntary rhythmic eye movements, not paralysis. Hemianopia is a loss of half the visual field, not a problem with eye movement. An analgesic is a pain-relieving medication and doesn’t relate to eye movement or double vision.
