objective(s):to the best of our knowledge, this is the first report on the contributions of gst genetic variants to the risk of diabetic retinopathy in an iranian population. therefore, the objective of this study was to determine whether sequence variation in glutathione s-transferase gene (gstm1 and gstt1) is associated with development of diabetic retinopathy in type 2 diabetes mellitus (t2d...

Medical research indicated that narrowing of the retinal blood vessels might be an early indicator cardiovascular diseases; one them is hypertensive retinopathy. This paper proposed new staging method retinopathy by measure ratio diameter artery and vein (AVR). The dataset used in this public Messidor color fundus image dataset. consists resizing using bicubic interpolation, optic disk detectio...

Several recent studies have provided evidence that good diabetes control is important to prevent diabetic retinopathy. However, some groups of patients develop diabetic retinopathy despite good control and others escape retinopathy despite poor control. This suggests the role of genetic factors in susceptibility to retinopathy. This article reviews the role of genetic factors in determining dia...

Introduction: Diabetic retinopathy is a major cause of blindness and a fundamental cause of disability in diabetic patients in the world. Investigation about the quality of life in these patients can help plan for taking nursing measures to prevent or control the disease and improve patients’ quality of life. Objective: This study aimed to determine the quality of life in patient...

objective: this research was conducted to evaluate the prevalence of diabetic retinopathy (dr) in patients who were unaware of their eye condition. materials and methods: a descriptive cross-sectional study was performed in a 12-month period on patients who were referred to meybod imam sadegh diabetes center. 152 patients who had no eye complaint were selected. pupil dilation was created by cyc...

PURPOSE To examine the potential of abnormal mfERGs to predict the development of diabetic retinopathy at corresponding retinal locations 1 year later. METHODS One eye of 11 diabetic patients with nonproliferative diabetic retinopathy (NPDR) and 11 diabetic patients without retinopathy were retested 12 months after initial testing. At each time, mfERGs were recorded from 103 retinal locations...

Diabetes mellitus is a global health problem affecting 366 million people worldwide and its prevalence is growing rapidly. Diabetic eye disease is present in up to 25% of diabetic subjects. Diabetic retinopathy is a chronic complication of diabetes that can result in blindness. Generally, there are two stages of diabetic retinopathy, non-proliferative and proliferative. The longer a person has ...

OBJECTIVES This retrospective, population-based, cross-sectional study evaluated the association between vitamin D deficiency and retinopathy severity in diabetic patients with poorly or well controlled glycaemia. Other potential risk factors for diabetic retinopathy severity were also assessed. METHODS The National Health and Nutrition Examination Survey (NHANES) 2005-2008 data were used for...

OBJECTIVE To identify the correlation between the development of retinopathy and macro-albuminuria and the other risk factors for the retinopathy in type 2 diabetic patients. MATERIAL AND METHOD This is a cross-sectional study. The authors studied 201 patients suffering from diabetes type 2. Fundoscopy was performed by ophthalmologists. Macro-albuminuria was assessed by urine strip (URICAN). ...

To assess the prevalence and risk factors for early and severe diabetic retinopathy and macular edema in a large cohort of patients with type 2 diabetes Retinopathy grading (any retinopathy, severe retinopathy, diabetic macular edema) and risk factors of 64784 were prospectively recorded between January 2000 and March 2013 and analyzed by Kaplan-Meier analysis and logistic regression. Retinopat...
