Eligibility Criteria

Age18 Years - 80 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • 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

You may not qualify if:

  • 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.
