目的：分析糖尿病视网膜病变(DR)合并视网膜静脉阻塞(RVO)的眼底特征及荧光素眼底血管造影(FFA)的图像特征。
方法：回顾性分析118例129眼DR合并RVO患者的视力、眼底、荧光素眼底血管造影(FFA)的图像特征及相关临床资料。
结果： DR合并RVO的患者118例中，双眼同时发病有11例22眼，其余皆为单眼，其中66眼表现为视网膜中央静脉阻塞(CRVO)，占51.2%，58眼表现为颞上分支静脉阻塞，占45.0%，其它分支静脉阻塞有5眼，占3.9%。FFA表现为：静脉阻塞区视网膜有大量神经纤维层出血，相应黄斑区荧光渗漏，掩盖了此眼DR的改变，对侧眼均可见DR不同级别的改变。
结论：糖尿病视网膜病变合并视网膜静脉阻塞眼底表现复杂，应与单一的糖尿病视网膜病变和视网膜静脉阻塞甄别。

[Abstract]
AIM: To observe the characteristics of fundus images and fluorescin angiography(FFA)in diabetic retinopathy(DR)combined with retinal vein occlusion(RVO).
METHODS: The clinical data of FFA and other related information of 118 patients(129 eyes)who were diagnosed as DR combined with RVO were retrospectively analyzed.
RESULTS: In the 118 cases of DR combined with RVO, only 11 patients were involved with both eyes. Central retinal vein occlusion(CRVO)was the most predominant(66 eyes, 51.2%), followed by temporal upper branch RVO(58 eyes, 45.0%), other branch RVO(5 eyes, 3.9%). FFA results showed that extensive hemorrhage was seen at the vein occlusion area, and disc and fovea of macula was involved with fluorescein leakage. At the same time, they covered DR change of this eye. The opposite eye had DR changes at different degrees.
CONCLUSION: The clinical and fundus changes of DR combined with RVO are of many characteristics and should be distinguished with single DR or RVO.
