Diabetic retinopathy is one of the main causes vision loss, and it can be identified through ophthalmological examinations that aim to locate presence retinal lesions such as Microaneurysms, Hemorrhages, Soft Exudates, Hard Exudates. The development computerized approaches perform instance segmentation these help in early diagnosis disease. However, instances artifacts retina a complex task due...

Diabetic retinopathy is the leading disease that occurs due to the diabetic mellitus. Several computer aided diagnosis helps ophthalmologists to diagnosis the severity of retinopathy but still the annual screening of retinal images is very important to detect diabetic retinopathy by an automatic assessment system for analyzing the images through region based method, filtering techniques, templa...

D iabetic retinopathy is the most frequent cause of new cases of blindness among adults aged 20 –74 years. During the first two decades of disease, nearly all patients with type 1 diabetes and 60% of patients with type 2 diabetes have retinopathy. In the Wisconsin Epidemiologic Study of Diabetic Retinopathy (WESDR), 3.6% of younger-onset patients (type 1 diabetes) and 1.6% of olderonset patient...

Diabetic retinopathy is a leading cause of visual impairment and blindness in developed countries due to macular edema and proliferative diabetic retinopathy (PDR). For both complications laser treatment may offer proven therapy: the Diabetic Retinopathy Study demonstrated that panretinal scatter photocoagulation reduces the risk of severe visual loss by >50% in eyes with high-risk characterist...

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...

BACKGROUND Folate deficiency is associated with cardiovascular disease, megaloblastic anemia, and with hyperhomocysteinemia. This study has been undertaken to investigate the role of folate status during the progression of the diabetic retinopathy. METHODS We measured the plasma levels of homocysteine, folic acid, and red cell folate in 70 diabetic type 2 patients with nonproliferative diabet...

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...

Aim: Diabetes Mellitus is a global public health challenge with major and potentially devastating complications, concomitant complications include retinopathy neuropathy due to hypoxia microvascular dysfunction. In this study, we investigated the effect of hyperbaric oxygen therapy as method transiently improve tissue oxygenation on diabetic in streptozotocin induced type-1 rat model (Wistar). ...

purpose: to study recordings of oscillatory potentials (ops) of the electroretinogram (erg) in diabetic eyes that have no visible fundus alterations, to ascertain whether changes in sensitivity are evident when compared with recordings from age-matched controls. methods: ops of the erg were measured from 68 eyes of 34 patients with diabetes without retinopathy and from 30 eyes of 15 normal subj...
