Silver wiring on fundoscopic exam is associated with which severity of hypertensive retinopathy?

• A. Mild
• B. Moderate
• C. Severe
• D. Malignant

Answer: (C)

Silver wiring arises from marked arteriolar sclerosis of the retinal vessels due to long-standing hypertension. As the vessel walls thicken and the lumen narrows, the normal light reflex becomes brighter and more silvery, signaling more advanced vascular change. This reflects severe hypertensive retinopathy, where arteriolar damage is extensive but not necessarily malignant; malignant hypertension would bring additional findings such as optic disc edema (papilledema) along with hemorrhages or exudates. So, the presence of silver wiring best indicates severe hypertensive retinopathy.
