Which vascular change is correctly paired with its indication?

Engorged vessels — hyperviscosity syndrome Perivascular cuffing — inflammatory disease Lipemia retinalis — inflammatory disease Lipemia retinalis — hyperlipidemia

Correct Answer:

Lipemia retinalis — hyperlipidemia

Explanation:

The key idea is how specific retinal vascular signs reflect systemic conditions. Lipemia retinalis is a classic sign of extreme hyperlipidemia: when triglyceride-rich lipoproteins are very high, the blood becomes milky and the retinal vessels take on a pale, creamy appearance. This appearance mirrors the lipid-laden blood within the vessels, so the indication is hyperlipidemia. Engorged vessels are more typical of hyperviscosity syndromes, where increased plasma viscosity slows flow and dilates retinal vessels. Perivascular cuffing indicates inflammation around vessels, not lipid disorders. Lipemia retinalis itself is not inflammatory, which is why pairing it with inflammatory disease isn’t correct.
