DETECTION OF BRIGHT LESIONS IN DIGITAL FUNDUS IMAGES Diabetic retinopathy is a serious complication of diabetes mellitus and primary cause of blindness in Indian adults. Bright lesions such as hard exudates and cottonwool spots are the visible signs of diabetic retinopathy. These bright lesions are also an indicator for the incidence of co-existent retinal edema. If present in the macular area,...

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...

AIMS To estimate the prevalence of diabetic retinopathy among self reported diabetics in a population of southern India. METHODS A cross sectional sample of subjects aged 50 years and older was selected using a cluster sampling technique from Palakkad district of Kerala state. Eligible subjects were identified through a door to door survey. Ocular examinations including visual acuity and ante...

OBJECTIVE To determine if improved foot sensitivity to the Semmes-Weinstein 10-g (5.07) monofilament, originally impaired because of diabetic peripheral neuropathy, might be associated with a reduced incidence of new diabetic foot wounds. DESIGN Retrospective cohort study using a health status questionnaire. SUBJECTS Sixty-eight individuals over age 64 with diabetes, diabetic peripheral neu...

A 22 year old man presented with a severe ischaemic diabetic retinopathy and, in spite of photocoagulation therapy, was blind in one eye 16 months after diagnosis. Four similar cases of aggressive diabetic retinopathy are reviewed. There is increasing evidence that a small group of young men with insulin dependent diabetes (IDD) may develop severe diabetic retinopathy at, or soon after, diagnosis.

BACKGROUND Diabetic retinopathy is an increasing cause of blindness. The prevalence of retinopathy in hospital attending diabetics in Ibadan is reported to be 42 %. This study assessed the barriers identified by patients and service providers to delivering good services for diabetic retinopathy in Ibadan, Nigeria, Sub-Saharan Africa. METHODS A qualitative survey using non-participatory observ...

Background and aims: The economic burden resulting from diabetic retinopathy (DR) consumes a major portion of resources allocated for health-care services. Cost-effectiveness of various interventions on DR and its complications has relatively been well explored in developed countries, but these are almost absent in developing countries. The present study was undertaken to assess the cost-effect...

BACKGROUND/AIMS Proteinuria, nearly a universal finding in progressive kidney disease, has been the subject of frequent recent analyses in the renal literature. Proteinuria is a hallmark of diabetic nephropathy: microalbuminuria is the principal early predictor for progression of diabetic glomerulopathy, and proteinuria may be viewed as a measure of the severity and promoter of progression of n...

Although abnormal iris vessels and secondary glaucoma in a patient with proliferative diabetic retinopathy was described over 8o years ago by Nettleship (i888), Salus (1928) was the first to call attention to rubeosis of the iris as a specific manifestation of long-term diabetes and to point out that the neovascularization of the iris resulted in haemorrhagic glaucoma. Neovascularization of the...

AIMS To determine whether software processing of digitised retinal images using a "sharpen" filter improves the ability to grade diabetic retinopathy. METHODS 150 macula centred retinal images were taken as 35 mm colour transparencies representing a spectrum of diabetic retinopathy, digitised, and graded in random order before and after the application of a sharpen filter (Adobe Photoshop). D...
