One of the major complications of diabetes is diabetic retinopathy. As manual analysis and diagnosis of large amount of images are time consuming, automatic detection and grading of diabetic retinopathy are desired. In this paper, we use fundus fluorescein angiography and color fundus images simultaneously, extract 6 features employing curvelet transform, and feed them to support vector machine...

OBJECTIVE The study was aimed at estimating the prevalence of type 2 diabetes mellitus and diabetic retinopathy in a rural population of South India. DESIGN A population-based cross-sectional study. PARTICIPANTS 13 079 participants were enumerated. METHODS A multistage cluster sampling method was used. All eligible participants underwent comprehensive eye examination. The fundi of all pat...

Diabetic retinopathy is caused by the retinal micro vasculature which may be formed as a result of diabetes mellitus. Blindness may appear as a result of unchecked and severe cases of diabetic retinopathy. Manual inspection of fundus images to check morphological changes in microaneurysms, exudates, blood vessels, hemorrhages, and macula is a very time-consuming and tedious work. It can be made...

abstractintroduction: diabetes mellitus is the most common human metabolic disease and chronic non healing diabetic foot ulcers are a critical complication for these patients. angipars is a new herbal extract which has been introduced to accelerate healing of these ulcers. the purpose of this study was to investigate the efficacy and safety of oral angipars in patients with chronic diabetic foo...

introduction: diabetic retinopathy (dr) is the single largest cause of sight loss and blindness in the working age population of western countries; it is the most common cause of blindness in adults between 20 and 60 years of age. early diagnosis of dr is critical for preventing vision loss so early detection of microaneurysms (mas) as the first signs of dr is important. this paper addresses th...

purpose: to determine the general population’s knowledge and awareness about cataract, glaucoma and diabetic retinopathy (dr) in tehran, the most populated and capital city of iran, in order to assess the need for health education programs. methods: this cross-sectional population-based survey was conducted during 2010 and a structured questionnaire was filled by 5 trained interviewers via tele...

It is suspected that radiation retinopathy is more likely to develop in an eye with preexisting diabetic retinopathy than in a normal eye. However, there is only one report of this occurring, at a radiation dose of 4500 rads. We present a woman with minimal diabetic retinopathy who had breast carcinoma which was treated with chemotherapy but metastasised to the choroid. Within nine months of ex...

The purpose of this study was to investigate the association between retinopathy and the levels of diabetic control found in type 2 non-insulin dependent diabetic patients. The study covered a four-year period and used retrospective, routinely recorded general practice and optometry records from 260 patients; those with retinopathy (n = 38) and those without retinopathy (n = 222). The study dem...

In spite of all advances in the understanding of chronic diabetic complications, diabetic retinopathy remains a significant clinical problem. The pathogenetic mechanisms leading to the development of diabetic retinopathy is indeed complex. Multiple interactive mechanisms may come into play leading to cellular damage and adaptive changes leading to the development of this devastating complicatio...
