Which symptom can indicate a stroke affecting vision?

• A. Dimness or loss of vision on one eye
• B. Hearing loss
• C. Tinnitus
• D. Dizziness with ringing

Answer: (A)

Sudden changes in vision point to disruption along the visual pathways. Dimness or loss of vision in one eye indicates a problem in the anterior visual pathway—the retina or optic nerve—often due to a vascular event affecting blood flow to that eye. This monocular deficit is a classic sign of a stroke involving the eye’s direct blood supply, such as the ophthalmic branch of the internal carotid system. If a stroke affects the brain’s visual cortex or optic radiations, the pattern is usually a loss of a visual field in both eyes on one side (a hemianopia), not just one eye. The other options involve hearing or balance systems rather than vision pathways, so they don’t align with a stroke presenting with vision disturbance.
