增殖型糖尿病视网膜病变(PDR)玻璃体切割术后再出血是影响视力预后的一个重要因素。我们对91例100眼术后出血进行分析,结果如下:一周内最易出血,50%以上在一月内。控制好血糖,半年内未出血则以后很少出血。原因有纤维血管膜残端、新生血管、晶体手术、硅油取出,激光不足。出血多难吸收时,积极治疗可改善视力预后。我们认为术中彻底剥膜,术后及时行眼底血管荧光造影(FFA),激光光凝,尽量保留晶体及后囊,无晶体眼慎重取油可有效防出血。
Proliferation-induced diabetic retinopathy (PDR) Rebleeding after vitrectomy is an important factor that affects vision prognosis. We analyzed 91 cases of 100 cases of postoperative bleeding, the results are as follows: the most vulnerable to bleeding within a week, 50% in January. Good blood sugar control, within six months after bleeding is rarely bleeding. Causes of fibrovascular stump, neovascular, crystal surgery, silicone removal, lack of laser. When bleeding is more difficult to absorb, active treatment can improve visual outcome. We believe that the surgery should be performed completely and the fundus fluorescein angiography (FFA) and laser photocoagulation should be performed immediately after surgery to keep the crystal and the posterior capsule as much as possible.
