Abstract
Background: Diabetes Mellitus is the most common endocrinologic disease in human and retinopathy is one of the most common complications. Etiology of this complication is yet unknown but one of the factors that can be effective on its production or progression is serum lipid. We aim to study the relationship between different degrees of diabetic retinopathy and serum lipids levels.
Methods: An observational cross-sectional study designed to study over 37 patients with diabetes mellitus type one and 157 patients with diabetes mellitus type two. Former was selected as sensus and latter was selected randomly from diabetic patients attending the diabetes clinic in Yazd during 2002. Inclusion criteria was duration of diabetes at least seven years from diagnosis. Statistical analysis performed by SPSS package edition 11 and wit statistical tests as Chi square, Fisher Exact and ANOVA.
Results: Among 194 cases, 74 cases were males and 120 females. 90 cases (46.4%) have normal total serum cholesterol and 104 (53.6%) hypercholestrolemia. In case of triglyceride 94 cases (48.4%) have normal serum triglyceride and 100 (51.6%) hypertriglyceridemia. Distribution of different degrees of diabetic retinopathy was statistically significant due to cholesterol and triglycerides (P-Value<0.05). In different groups of sex, diabetic retinopathy was more prevalent if there was hypertriglyceridemia or hypercholesterolemia. This was correct about different groups of age and type of diabetes. This means that in different groups of age and type of diabetes, diabetic retinopathy was more prevalent if there was hypertriglyceridemia or hypercholesterolemia.
Conclusion: Prevalence of diabetic retinopathy is higher in cases with hypertriglyceridemia or hypercholesterolemia than cases with normal serum triglyceride or cholesterole.
