Volume 60, Issue 6 (9-2002)
Abstract

Introduction: Coronary artery disease (CAD) and its complications are the most prevalent etiology of mortality all over the world and diabetes mellitus (DM) is one of its risk factors. In this study prevalence of MI and unstable angina have been compared with different kinds of retinopathy and their severity.

Materials and methods: This study is a descriptive, cross sectional one that performed on 100 patients admitted in Imam, Farabi and Amir Alam Hospitals.

Results: Most important findings are as below: 1) Non-proliferative diabetic retinopathy (NPDR) are more prevalent than proliferative diabetic retinopathy (PDR), 41 Vs 17 cases, and 24 person were normal in MI population. And 12 persons had NPDR and 2 PDR and 5 normal in unstable angina. 2) Different diabetic retinopathy lesion were: 23 Venous dilation, 22 aneurysme, 18 hemorrhagic, 11 neovascularization, 10 macula edema, 6 retroretinal detachment, 2 gliosis. 3) on the point of presence or absence of diabetic retinopathy (DR), 72 percent had some kind of DR and 28 percent had nothing. Finally, in MI population 58 patients (70 percent) had DR and 24 patients (30 percent) didn't have any. In unstable angina 14 patients (77 percent) had diabetic retinopathy and 4 didn't have (23 percent).

Conclusion: Regarding the lack of facilities and shortcoming of necessary data, it was not possible to conduct a prospective investigation in this item, so the design and implementation of a prospective study based on enough cases and controls is strongly recommended.

Volume 64, Issue 11 (10-2006)
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.

Volume 65, Issue 7 (10-2007)
Abstract

Background: The aim of this study was to estimate the prevalence, severity, and risk factors for diabetic retinopathy in diabetic cases admitted for non-ocular diabetic complications and to investigate the association between retinopathy and these complications.

Methods: In this cross-sectional study, 84 diabetic patients admitted to our university-affiliated hospital for non-ocular diabetic complications were fully evaluated for proliferative and nonproliferative diabetic retinopathy. Cases of nonproliferative retinopathy (NPDR) were graded as microaneurysm, mild, moderate or severe. To determine the association of retinopathy with the complications that caused hospitalization, statistical analysis was performed using SPSS ver. 11.5.

Results: The prevalence of diabetic retinopathy among our cases was 77.4% (65 patients), with proliferative diabetic retinopathy (PDR) present in 23 patients (35.4% of the retinopathy cases). Diabetic retinopathy was higher in patients who had been hospitalized for nephropathy than in patients with diabetic foot and diabetic ketoacidosis (DKA, p=0.001), and higher in those hospitalized for diabetic foot than for DKA (p=0.008). Among the 35 patients who had nephropathy and retinopathy, 16 subjects (45.7%) had PDR, and the other 19 subjects had NPDR. Twenty-seven patients had diabetic foot and retinopathy, six (22.7%) of whom had PDR, and 21 (77.8%) had NPDR. Factors significantly related to the occurrence of diabetic retinopathy were type 2 diabetes, presence of hypertension, elevated serum levels of creatinine, duration of diabetes and coexisting nephropathy or diabetic foot (all with p values <0.05). In the logistic regression model, diabetic duration had a slight association with PDR (p=0.06).

Conclusion: Our data suggest that diabetic retinopathy in our patients is common, especially in patients with nephropathy. In addition to glycemic control, lowering of serum cholesterol and triglycerides as well as blood pressure may be effective in lowering the prevalence of diabetic retinopathy.

Volume 68, Issue 11 (2-2011)
Abstract

Background: Diabetes is a chronic non-communicable disease with increasing prevalence. Retinopathy is one of the main complications of diabetes. Early diagnosis and treatment of retinopathy can reduce the risk of low vision and blindness. The aim of this study was to apply regression analysis of current status data to determine risk factors of diabetic retinopathy in patients with type 2 diabetes being referred to the Ophthalmology Clinic of Yazd Diabetes Research Center, Iran.

Methods: In this analytical-observational study, 459 patients with type 2 diabetes were enrolled in the study and the ophthalmic examinations done by an ophthalmologist included visual acuity, intraocular pressure (IOP) measurement and slit-lamp examination. After pupil dilatation, funduscopy was done and the patients were classified according to ETDRS criteria. A proportional hazard model for current status data was used to identify the risk factors for retinopathy.

Results: The hazard rate of having retinopathy increased by 5% for an increase of one year in the duration of diabetes (p<0.05) and the hazard rate of having retinopathy was 1.1 times greater in patients who had used insulin for diabetes compared with other type 2 diabetes patients (p<0.05).

Conclusion: This study showed that a history of hypertension may reduce the risks of diabetic retinopathy. In patients with the early diagnosis of diabetes, regular examination of the fundus, blood sugar control and tight control of high blood pressure are recommended.

Volume 82, Issue 5 (7-2024)
Abstract
Background: Diabetic retinopathy is one of the main causes of blindness in the world and one of the causes of disability in diabetic patients. However, no study has been conducted in Iran to Comparison of Quality of Life between Diabetic Patients With and Without Retinopathy.
Methods: This descriptive-analytical study was conducted on 183 diabetic patients referred to the Jahrom Honari Clinic from October to February 2023. The patients were divided into two groups: diabetic patients without retinopathy complications and diabetic patients with retinopathy complications. The data collection tool included two demographic information questionnaires and a quality of life questionnaire (DQOL-BCI). The data of the two groups and subgroups were compared and analyzed using SPSS version 21 software and descriptive statistics (frequency, percentage, mean, and standard deviation) and inferential statistical tests (chi-square, t-test, ANOVA, Pearson correlation coefficient) at a significance level of P<0.05.
Results: The majority of diabetic patients participating in the study in the group with retinopathy (70.3%) and the group without retinopathy (75%) were male. The groups of Diabetic Patients With and Without Retinopathy did not differ significantly from each other in terms of demographic variables and were similar. There was a significant difference between Diabetic Patients With and Without Retinopathy in terms of average quality of life (P>0.001). The mean quality of life in the group of diabetic patients with retinopathy (41.19±7.97) was higher than that of the group of diabetic patients without retinopathy (37.22±7.37). There was no significant difference between the mean quality of life and demographic variables in diabetic patients without retinopathy and diabetic patients with retinopathy (P<0.001).
Conclusion: That patients with retinopathy had a higher quality of life than the group without retinopathy. These results were obtained while none of the demographic variables such as age, gender, marital status, and education level had a significant relationship with the quality of life of these patients.
