Vitreous hemorrhage
Retina & Vitreous
Key Points
- •VH is a sign, not a diagnosis - always identify and treat the underlying cause; the most common causes are proliferative diabetic retinopathy (30–40%) and PVD with retinal tear (15–30%)
- •B-scan ultrasonography is mandatory in every case of dense VH to rule out retinal detachment - this single test determines the urgency of management
- •A symptomatic PVD with VH has ~70% chance of harbouring a retinal tear - close follow-up within 1 week is essential to identify and treat any break before RD develops
- •Ghost cell glaucoma (elevated IOP from degenerated RBCs blocking the trabecular meshwork) occurs 1–3 months after VH - a late complication to recognise
- •Anti-VEGF can be injected through dense diabetic VH as a bridge to PRP; surgical vitrectomy is indicated for non-clearing VH (>1 month type 1 DM; >2–3 months type 2 DM) or any VH with retinal detachment
