Which vascular changes are associated with fundic disease?

• A. Attenuation, engorgement, or hemorrhage
• B. Dazzle reflex unaffected
• C. Increased retinal brightness without change
• D. Normal vascular appearance

Answer: (A)

Vascular changes in the fundus reflect retinal microvascular pathology. The key findings you’d expect with fundus disease are narrowing of retinal arteries (attenuation), dilation of retinal veins (engorgement), and hemorrhages. Attenuation signals chronic arterial constriction or thickening of arteriolar walls, engorgement shows venous congestion, and hemorrhages indicate fragile or ruptured vessels from underlying disease. This combination is commonly seen across fundus diseases such as hypertensive and diabetic retinopathy, making it the best description of vascular changes to look for. The other options don’t fit the typical vascular picture: a dazzle reflex being unaffected isn’t a vascular change, increased retinal brightness without change isn’t about vessels, and a normal vascular appearance would not align with fundus pathology.
