Relationship between dyslipidemia and diabetic retinopathy in non-insulin-dependent diabetes mellitus

Objective To investigate the relationship between dyslipidemia and diabetic retinopathy in non-insulin-dependent diabetes mellitus（NIDDM） patients． Methods In 55 health controls，60 NIDDM patients with DR and 75 NIDDM patients without DR，the plasma total cholesterol（TC），triglycerides（TG），high-density lipoprotein（HDL）and HDL subfractions，fasting plasma glucose（FPG），fasting plasma insulin（FINS）and glycosylated hemogolbin（HbA 1C）were measured，and the plasma lowdensity lipoprotein （LDL） and very lowdensity lipoprotein（VLDL）were caculated． Results In NIDDM patients with DR，the　TC，LDL，FPG，HbA 1C and duration of NIDDM were higher or longer than those in NIDDM patients without DR．Moreover，the TC，LDL，FPG、FINS、HbA 1C and dutation of NIDDM were increased or lengthened in NIDDM patients with proliferative DR as compared with those with backgroud DR．The correlation analysis showed　the severity of DR was positively correlated with TC，LDL，HbA 1C and duration of NIDDM． Conclusion Dyslipidemia may play some role in the onset and development of DR． (Chin J Ocul Fundus Dis,1998,14:21-23)
