Hypertensive Retinopathy
Definition / Overview
Retinal manifestations of systemic hypertension, ranging from mild arteriolar changes to severe retinopathy with disc edema. Hypertension is the strongest systemic risk factor for retinal-arterial-macroaneurysm (present in 75% of RAM cases).
Key Details
- Classification: Keith-Wagener-Barker or Wong-Mitchell grading systems â details to be added from dedicated source
- Arteriolar changes: generalized/focal narrowing, AV nicking, copper/silver wiring
- Retinal signs: flame hemorrhages, cotton-wool spots, hard exudates (macular star)
- Severe: disc edema (malignant hypertension)
- Arteriosclerotic changes in vessel walls are the pathological basis for RAM formation â focal ischemia from embolic damage leads to intimal collagen remodeling and vessel dilation
Clinical Relevance
Every patient diagnosed with RAM requires a systemic workup for hypertension. Control of hypertension is the primary prevention strategy for RAM.
Associations
- retinal-arterial-macroaneurysm â RAM occurs in the setting of hypertensive arteriolosclerosis
- branch-retinal-vein-occlusion â hypertension is a risk factor
- diabetic-retinopathy â overlapping risk factor population
