BACKGROUND The study describes the relationship of retinal vascular geometry (RVG) to severity of diabetic retinopathy (DR), and its predictive role for subsequent development of proliferative diabetic retinopathy (PDR). METHODS The research project comprises of two stages. Firstly, a comparative study of diabetic patients with different grades of DR. (No DR: Minimal non-proliferative DR: Sev...

AIM To estimate the overall prevalence of diabetic retinopathy (DR) in Iran by a systematic review and Meta-analysis. METHODS We conducted a search of all published literature on diabetic patients for the prevalence of DR using Web of Sciences, PubMed, Scopus, Google Scholar, and national electronic databases SID, Magiran, and Iranmedex from their inception until September 2016 with standard ...

PURPOSE To evaluate the presence of hyperreflective spots (HRS) in diabetic patients without clinically detectable retinopathy (no DR) or with nonproliferative mild to moderate retinopathy (DR) without macular edema, and compare the results to controls. METHODS 36 subjects were enrolled: 12 with no DR, 12 with DR, and 12 normal subjects who served as controls. All studied subjects underwent f...

OBJECTIVE Omentin, a new discovered adipokine, is implicated to inhibit inflammation. Inflammation is one important mechanism of diabetic retinopathy (DR). The purpose of this work was to evaluate serum and vitreous concentrations of omentin-1 in patients with diabetic retinopathy (DR). METHODS This study enrolled 204 diabetic patients (60 without DR, 49 with NPDR, and 95 with PDR) and 65 con...

diabetic retinopathy is the leading cause of blindness in the world. strict control of blood sugar, blood pressure, laser therapy, pharmacotherapy and vitrectomy are of among common diabetic retinopathy treatments. further studies to investigate the effect of protein kinase c inhibitors, angiotensin converting enzyme inhibitors, growth hormone and other proposed treatments for diabetic retinopa...

Diabetic retinopathy (DR) is a common and potentially sight-threatening complication of diabetes. Early detection accurate diagnosis DR are crucial for effective treatment prevention vision loss. In recent years, deep learning techniques have shown remarkable success in various medical imaging tasks. This research paper presents general model designed specifically detecting diabetic retinal ima...

BACKGROUND The influence of diabetes mellitus on ocular pulse amplitude (OPA), an indirect measure of choroidal perfusion, is unclear. METHODS OPA, using the Langham ocular blood flow (OBF) system, applanation intraocular pressure (IOP), systemic blood pressure (BP), heart rate, and haemoglobin (Hb) A(1c) were measured in patients with insulin dependent diabetes mellitus (IDDM) with no (DR-0,...

PURPOSE To study the subbasal corneal plexus (SCP) in patients with diabetic retinopathy (DR) treated or nontreated with panretinal Argon laser photocoagulation (ALP). METHOD Fifty consecutive patients with DR and 50 age- and sex-matched normal control subjects were examined with retinal tomography by a masked evaluator. The following subbasal plexus nerves parameters were considered: number ...

INTRODUCTION Color Doppler Imaging (CDI) is used widely to study retrobulbar circulation. OBJECTIVES To determine the association between progression of diabetic retinopathy (DR) and alterations in retrobulbar arterial circulation using CDI studies. MATERIALS AND METHODS Prospective observational case series. It is single institutional study of 50 eyes of nonproliferative diabetic retinopat...

BACKGROUND Diabetic retinopathy (DR) is the most common microvascular complication of diabetes. It can lead to significant visual loss. The aim of this study was to determine the frequency and clinical profile of diabetic retinopathy, and assess the outcomes of laser photocoagulation therapy in a diabetic population in Cameroon. METHODS We carried out a prospective cohort study during 24 mont...
