Branch Retinal Vein Occlusion (BRVO)
Definition / Overview
Occlusion of a branch of the central retinal vein, typically at an arteriovenous crossing point. One of the most common retinal vascular disorders. Mentioned in the RAM article as a secondary cause of macroaneurysm formation.
Key Details
- Details to be added from dedicated source â pathophysiology, classification, management, trials (BRAVO, VIBRANT, SCORE)
- BRVO can cause secondary retinal-arterial-macroaneurysm formation
Clinical Relevance
When a macroaneurysm is found, BRVO should be considered as a potential underlying cause (alongside diabetic-retinopathy, radiation-retinopathy, and retinal arteritis).
Associations
- retinal-arterial-macroaneurysm â secondary cause
- hypertensive-retinopathy â shared risk factor (hypertension)
