Branch retinal vein occlusion
Retina & Vitreous
Key Points
- •BRVO is the second most common retinal vascular disorder; occurs at AV crossings due to arteriosclerotic compression; hypertension is the strongest risk factor
- •Ischaemic BRVO (≥5 DA non-perfusion on FFA) carries ~40% NV risk - non-ischaemic BRVO has <5% NV risk and better visual prognosis
- •Anti-VEGF is first-line for BRVO macular oedema: BRAVO (ranibizumab +18.3 letters) and VIBRANT (aflibercept +17.0 letters, superior to grid laser)
- •BVOS established grid laser for persistent macular oedema and sectoral scatter laser (not PRP) for ischaemic BRVO with NV
