摘要
观察糖尿病患者２５２例５０１只眼的眼底荧光血管造影，分析新生血管发生情况和视力预后。其中背景型３０２只限，增殖型１６２只眼，未发现病变者３７只眼。增殖型患者病程５年以下者占６．１％，５～１０年者占３１．０％，１０年以上者增至５４．６％。新生血管位于视网膜者１３６只眼，合并视盘新生血管者４９只眼。玻璃体出血５１只眼，占增殖型眼的３１．５％。本组患者视网膜新生血管共５１５簇，多分布在距视盘３～６ＤＤ的范围。有新生血管眼视力０．５以上者仅占２９．０％，而无新生血管者占６２．９％（Ｐ＜０．００５）。
The retinal neovascularization(NVR)and visual prognosis were analyzed in 501 eyes of 25 2 cases with diabetic retinopathy(DR)using fluorescein angiography。 The types of these cases were 302 eyes with background DR,162 eyes with proliferative DR(PDR),and 37 eyes without any change.The incidence of PDR was 6.1%when duration of diabetes was under 5 years,and increased to 31.0%in patients from 5-10 years,and 54.6%in thoseL with 10 or more years of diabetes。 Retinal neo-vasculariyation was found in this group in 136 eyes and among them disc neovascularization still found in 49 eyes. The incidence of vitreous hemorrhage was 31.5%(51/162).515 clusters of newly formed vessels(NV)were identified in this series,and they were found locating in the midperipheral retinal at a distance of 3～6DD away from the disc. The visual acuity was 0.5 or more in only 29.0%eyes with NV,while in 62.9%eyes without NV.
