Abstract:

Objective   To study the relationship between hyperlipidemia and incidence of retinal vein occlusion by observing serum lipid changes of patients with retinal vein occlusion. Methods  In this case-control study, the patient group included 46 patients with retinal vein occlusion who received no drug treatment, while the control group included 45 healthy people without retinal vascular disease. There were no significant differences in age and gender between the two groups. The levels of  total  serum cholesterol, triglycerides, low density lipoprotein cholesterol and high density lipoprotein cholesterol were measured and compared. Results  The levels of total cholesterol, triglycerides, low density lipoprotein cholesterol in the patient group were significantly higher than those in the control group (P＜0.05), while the level of high density lipoprotein cholesterol was significantly lower than that in the control group (P＜0.05). There was no significant difference between the levels mentioned above between the patients with central retinal vein occlusion and those with branch retinal vein occlusion (P＞0.05). Conclusion  There is a close relationship between the hyperlipidemia and the incidence of retinal vein occlusion.
