Objectives of Study:

To evaluate and compare the intraoperative precision of 10k/25G beveled-tip probe (BTP) versus 5k/23G flat-tip probe (FTP) in Pars Plana Vitrectomy (PPV) in day surgery for the treatment of Proliferative Diabetic Retinopathy (PDR) patients with fibrovascular proliferation (FVP)

2》根据患者术中表现,纳入FVP 2-4级患者。(FVP评级标准:根据玻璃体视网膜粘连的严重程度分为四级:多点粘连无或仅伴一个部位的纤维增殖膜黏连(1级);一个以上但少于三个部位的纤维增殖膜伴广泛粘连,增殖膜位于赤道后(2级);三个及以上部位广泛粘连,位于赤道后方或延伸至赤道前一象限内(3级);广泛粘连延伸至赤道前一个以上象限(4级)[7]。
3》患者知情并同意。
4》对照组的数据将根据2020/1-2022/6的手术录像评价FVP分级并按1:3进行匹配。

The patients should have ability to give informed consent.
The data of control group will be matched based on the extent of FVP* from the surgery recording of a retrospective cohort 2020/1~2022/10 (over 160 cases) with matching rate> 1:3

排除标准:

1》无纤维血管增生的PDR,或术中观察的FVP为1级;
