About this trial

This is an interventional treatment trial for Anti-VEGF

Eligibility Criteria

18 Years - 80 Years (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  1. Age≥18 years old;
  2. type 1 or type 2 diabetes.
  3. proliferative diabetic retinopathy with vitreous hemorrhage, and conservative treatment of vitreous hemorrhage without obvious absorption for 1 month requires vitreoretinal surgery;
  4. The postoperative refractive medium is clear and the pupil is large enough to obtain sufficient clear fundus

Exclusion Criteria:

  1. Previously received panretinal photocoagulation or unfinished panretinal photocoagulation;
  2. Pulling retinal detachment involving the macula or the presence of extensive fiber proliferation requires silicone oil filling;
  3. anterior chamber neovascularization or neovascular glaucoma;
  4. other vascular diseases such as retinal vein occlusion, arterial occlusion, etc;
  5. received intraocular anti-VEGF therapy or triamcinolone acetonide treatment which are still in the treatment period.
