Anti-VEGF Instead of Intraoperative Fan-shaped Photocoagulation in BRVO Combined With Vitreous Hemorrhage

Feasibility Study of Anti-VEGF Instead of Intraoperative Fan-shaped Photocoagulation in BRVO Combined With Vitreous Hemorrhage

To evaluate the efficacy and safety of Anti-VEGF instead of intraoperative fan-shaped photocoagulation in BRVO combined with vitreous hemorrhage.

Inclusion Criteria:

1. Age ≥ 18 years old;
2. BRVO is diagnosed
3. Vitreous hemorrhage
4. Vitreous hemorrhage combined with mild retinal fibrovascular proliferation (early fibrous vascular membrane, thin fibrous vascular membrane, loose retinal adhesion and intact local retinal structure)

Exclusion Criteria:

1. BRVO combined with severe retinal fibrovascular proliferation (long-term fibrovascular membrane, thick fibrous vascular membrane and tightly attached to the retina, deformation of local retinal, retinal tear or suspension of retinal vein )
2. BRVO combined with retinal detachment
3. Retinal veins are completely whitened
4. iris neovascularization or neovascular glaucoma
5. Combined glaucoma
6. combined with other retinopathy
7. Received anti-VEGF treatment within 3 months before surgery
