Abstract:AIM: To analyze both the effects of different risk factors on incidence of retinal vein occlusion and the comparison of difference between risk factors of RVO subgroups.
METHODS:Retrospective case control study. 79 cases of patients treated were collected as RVO group. These cases were further classified into high CRT group(26 cases)and low CRT group(53 cases)according to the CRT whether it is greater than 369μm. In the same time, 59 cases of patients who were conducted surgery of ophthalmology ward in our hospital were also collected. Statistical analysis of risk factors.
RESULTS: After a comparison between these factors and control group, it turns out that there are statistical differences on high blood, carotid artery plaque and HHCY in RVO group(P<0.05). The analysis conducted on two CRT groups revealed that difference exist in obstruction site and smoking(P<0.05).
CONCLUSION: Hypertension, carotid plaque and HHCY are risk factors of RVO. In the two CRT groups, the factors that may affect CRT are obstruction site and smoking.
