Objective—A prospective cohort study was designed to clarify the relations between occupational exposure to carbon disulphide (CS2) and its eVects on arteriosclerosis in workers in 11 Japanese rayon manufacturing factories. This report is a cross sectional baseline observation in the first study year. Methods—Study subjects were 432 male rayon workers (mean (range) age 35.5 (19.1–47.8); duratio...

Diabetic Retinopathy is a microvascular complication of diabetes mellitus. According to WHO (World Health Organization), there are more than 347 billion people who suffer from diabetes. This disease will become the seventh leading cause death in world 2030. Based on research Indonesia, it estimated that 42.6% diabetic retinopathy. Therefore, this final project plans system assist doctors identi...

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...

Microaneurysms (MAs) are known to be the early signs of diabetic retinopathy (DR). An automated MA detection system based on curvelet transform is proposed for color fundus image analysis. Candidates of MA were extracted in two parallel steps. In step one, blood vessels were removed from preprocessed green band image and preliminary MA candidates were selected by local thresholding technique. I...

Article history: Received : 07 April, 2017 Accepted : 12 May, 2017 Online: 04 June, 2017 The presence of microaneurysms(MAs) in retinal images is a pathognomonic sign of Diabetic Retinopathy (DR). This is one of the leading causes of blindness in the working population worldwide. This paper introduces a novel algorithm that combines information from spatial views of the retina for the purpose o...

We compared the performance of three computer based classification methods when applied to the problem of detecting microaneurysms on digitised angiographic images of the retina. An automated image processing system segmented 'candidate' objects (microaneurysms or spurious objects), and produced a list of features on each candidate for use by the classifiers. We compared an empirically derived ...

Purpose To test the risk of progression to macular edema (ME) of different phenotypes of mild nonproliferative diabetic retinopathy (NPDR). Methods Data from 882 patients with mild NPDR, Early Treatment Diabetic Retinopathy Study grades 20 and 35, with no prior laser treatment, enrolled in four separate longitudinal studies during 2007-2015 using the same reading center and with the same incl...
