About this trial
This is an interventional treatment trial for Anti-VEGF
Eligibility Criteria
Inclusion Criteria:
- Age≥18 years old;
- type 1 or type 2 diabetes.
- proliferative diabetic retinopathy with vitreous hemorrhage, and conservative treatment of vitreous hemorrhage without obvious absorption for 1 month requires vitreoretinal surgery;
- The postoperative refractive medium is clear and the pupil is large enough to obtain sufficient clear fundus
Exclusion Criteria:
- Previously received panretinal photocoagulation or unfinished panretinal photocoagulation;
- Pulling retinal detachment involving the macula or the presence of extensive fiber proliferation requires silicone oil filling;
- anterior chamber neovascularization or neovascular glaucoma;
- other vascular diseases such as retinal vein occlusion, arterial occlusion, etc;
- received intraocular anti-VEGF therapy or triamcinolone acetonide treatment which are still in the treatment period.
