Brief Summary:
The goal of this prospective randomized controlled study is to compare the therapeutic effect of injecting anti-VEGF drugs before surgery for patients with proliferative diabetic retinopathy at different time points. At present, studies have confirmed that anti-VEGF drugs are effective in inhibiting fundus neovascularization in proliferative diabetic retinopathy. The main question it aims to answer is which time point is better to injecting anti-VEGF drugs before surgery for patients with proliferative diabetic retinopathy.
Participants will be randomly divided into three groups. And time points of injecting anti-VEGF drugs before surgery for each group will be 3 days, 7 days, 14 days. And we have a new technology that can have fluorescein fundus angiography during operation, so it can reflect the condition of fundus neovascularization immediately and precisely. In that case, we can compare the Inhibitory effect of anti-VEGF drugs on fundus neovascularization at different time points.
