Clinical analysis on diabetic retinopathy combined with retinal vein obstruction

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.
