作者通过对124例视网膜静脉阻塞的回顾性研究,观察合并糖尿病者视网膜新生血管形成的发生率是否高于无糖尿病者。结果表明,视网膜中央静脉阻塞合并糖尿病时,发生视网膜新生血管形成的比例为68.8%;而无糖尿病者为27.8%。视网膜分枝静脉阻塞无论视网膜新生血管形成是否合并糖尿病,视网膜新生血管形成的发生率均无明显差异。病人和方法:作者将观察病例分为视网膜 The authors of a retrospective study of 124 cases of retinal vein occlusion to observe whether the incidence of retinal neovascularization in diabetic patients with diabetes than those without. The results showed that retinal neovascularization was associated with a 68.8% incidence of retinal central vein occlusion with diabetes and 27.8% with no diabetes. Retinal branch vein occlusion retinal neovascularization no significant difference in the incidence of retinal neovascularization regardless of retinal neovascularization is associated with diabetes. Patients and Methods: The authors divided the observed cases into retina
