Introduction: Patients with diabetes are prone to develop complications related to the retina. So far, several genes have been reported in connection with the progression of retinopathy, and a group of these genes is genes involved in angiogenesis. CXCL12 and CXCR4 genes are among the most important genes in this path, which have been less studied and investigated. The aim of this study was to ...

Abstract Background and Aim: Over the past few decades, there has been a dramatic increase in clinical research with the aim of investigating the underlying mechanisms of type 2 diabetic retinopathy disorder. The aim of this study was to compare active memory, inhibition of response, and the dimensions of nature and character in type 2 diabetic retinopathy and normal individuals in Tabriz. Mate...
Background: Anemia may be considered to be an independent risk factor for the development of diabetic retinopathy (DR) in patients with renal failure. The purpose of this study was to investigate the association between blood hemoglobin level and retinopathy in diabetic patients with normal renal function tests.Methods: From 2009 to 2011, 1100 diabetic patients underwent retinal examination. Am...
In the present study, we have decided to evaluate if serum transforming growth factor-beta 1 (TGF- β 1) concentrations may have diagnostic value in predicting the occurrence of diabetic retinopathy (DR) in juvenile patients with type 1 diabetes mellitus (T1DM). The study included 81 children and adolescents with T1DM and 19 control subjects. All study participants had biochemical parameters exa...
Background and purpose: The aim of this study was to identify the factors affecting the progression of retinopathy in patients with type 2 diabetes. Materials and methods: In this historical prospective cohort study, 728 patients with type 2 diabetes, attending Sari Tooba Clinic, were followed up for retinopathy. Data analysis was performed using accelerated failure time Weibull regression mod...
Eye diseases such as diabetic retinopathy (DR) affect a large number of the population. Retinal fundus photographs are widely used in the diagnosis and treatment of various eye diseases in clinics. It is also one of the main resources for mass screening of diabetic retinopathy. The resulting retinal images must be examined by an expert human grader in a cumbersome and time-consuming diagnosis p...
