In hypertensive retinopathy staging, which finding corresponds to stage 3?

• A. Attenuation
• B. AV crossing
• C. Cotton-wool spots, hemorrhages, exudates, micro/macroaneurysms, VO/AO, neovascularization, Elschnig spots
• D. ONH edema, macular star, venous engorgement

Answer: (C)

Hypertensive retinopathy staging rises with increasing retinal vascular damage from high blood pressure. Stage 3 is defined by more advanced nonproliferative changes, specifically the appearance of cotton-wool spots (nerve fiber layer microinfarcts), flame-shaped hemorrhages, hard exudates, and microaneurysms. This combination signals a progression beyond simple arteriolar narrowing or AV nicking (stages 1 and 2) but not yet the papilledema that marks stage 4. The option lists the features that characterize these stage-3 changes, making it the best match. Signs like attenuation or AV crossing changes point to earlier stages, while optic disc edema (papilledema) indicates stage 4, and elements such as Elschnig spots or neovascularization reflect more severe or malignant hypertensive changes beyond stage 3.
