Photocoagulation is an accepted method of local treatment for proliferative diabetic retinopathy. It has been shown that 73 25 per cent. of eyes with proliferative diabetic retinopathy have new vessels on the optic disc at the initial visit (Taylor and Dobree, I970). These vessels cannot be treated directly by photocoagulation. Aiello, Beetham, Balodimos, Chazan, and Bradley (I969) treated all ...

Objectives. We investigated the relationship between the stage of diabetic retinopathy and pulse wave velocity (PWV). Methods. This was a cross-sectional study of 689 patients (406 men and 283 women) with type 2 diabetes who were admitted to our hospital from 2004 to 2007. Brachial-ankle pulse wave velocity (baPWV) was measured by an arterial pressure measurement device as PWV/ABI. Diagnosis of...

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...

Diabetes mellitus is one of the most frequently occurring metabolic disorders (DMs), impairing healthy life around globe, with mild-to-severe secondary complications. DM associated complications, including diabetic retinopathy (DR), which damages retina and can lead to vision loss. Diabetic patients often suffer from extreme retinal capillary aneurysms, hemorrhage, edema, likely non-proliferati...

BACKGROUND Non-proliferative diabetic retinopathy is the early stage of diabetic retinopathy. Automatic detection of non-proliferative diabetic retinopathy is significant for clinical diagnosis, early screening and course progression of patients. METHODS This paper introduces the design and implementation of an automatic system for screening non-proliferative diabetic retinopathy based on col...

Diabetes mellitus is a heterogeneous clinical syndrome characterized by hyperglycaemia and the long-term complications are retinopathy, neuropathy, nephropathy, and cardiomyopathy. It is a leading cause of blindness. Diabetic retinopathy is the progressive pathological alterations in the retinal microvasculature, leading to areas of retinal nonperfusion, increased vascular permeability, and the...

AIM To summarize findings from studies reporting the prevalence and incidence of diabetic retinopathy and diabetic maculopathy in African countries in light of the rising prevalence of diabetes mellitus. METHODS Using a predefined search strategy, we systematically searched MEDLINE, EMBASE, Science Citation index and Conference Proceedings Citation index, African Index Medicus and the grey li...

Diabetic retinopathy has become one of the major causes of adult blindness in many countries (Winter, I960; Vedel-Jensen, I962; Caird and Garrett, I963; Lee, McMeel, Schepens, and Field, I966; Caird, Burditt, and Draper, I968; Caird, Pirie, and Ramsell, I969; Lindstedt, I969). Proliferative retinopathy is the severest form of the diabetic fundus disease, and although it occurs in only a small p...

OBJECTIVE Diabetic nephropathy clusters in families, suggesting that genetic factors play a role in its pathogenesis. We investigated whether similar clustering exists for proliferative retinopathy in families with two or more siblings with type 1 diabetes. RESEARCH DESIGN AND METHODS The FinnDiane Study has characterized 20% (4,800 patients) of adults with type 1 diabetes in Finland. In 188 ...

BACKGROUND Diabetic retinopathy is one of the most common and serious complications of type 2 diabetes mellitus and a leading cause of blindness not only in Pakistan but also worldwide. So we conducted this study to record the frequency of diabetic retinopathy in known diabetic patients ten years after diagnosis of type 2 diabetes mellitus. METHODS The study was conducted at Liaquat Universit...
