Early Detection of Diabetic Retinopathy in Fluorescent Angiography Retinal Images Using Image Processing Methods
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...
متن کاملAutomatic Detection of Microaneurysms in Color Fundus Images using a Local Radon Transform Method
Introduction: Diabetic retinopathy (DR) is one of the most serious and most frequent eye diseases in the world and the most common cause of blindness in adults between 20 and 60 years of age. Following 15 years of diabetes, about 2% of the diabetic patients are blind and 10% suffer from vision impairment due to DR complications. This paper addresses the automatic detection of microaneurysms (MA...
متن کاملHyperoxia improves contrast sensitivity in early diabetic retinopathy.
AIM The cause of vascular and visual pathology in diabetic retinopathy remains unknown. If retinal hypoxia plays a role, then early in the course of diabetes 100% oxygen breathing should normalise both contrast sensitivity and retinal blood flow. METHODS This hypothesis was tested in 12 diabetic patients with minimal retinopathy who, none the less, exhibited reduced contrast sensitivity (p = ...
متن کاملAbnormal Cambridge low-contrast grating sensitivity results associated with diabetic retinopathy as a potential screening tool.
Contrast sensitivity is proposed as a potential screening tool for the early detection of diabetic retinopathy. A cross-sectional study was performed in a tertiary referral university eye centre. A total of 80 diabetes patients were recruited and tests were performed on 154 eyes. Contrast sensitivity was checked using Cambridge low-contrast grating. Abnormal contrast sensitivity was observed in...
متن کاملVisual evoked potential and contrast sensitivity function in diabetic retinopathy.
survival in elderly patients but enormously enhances the quality of remaining life. How often hypopituitarism is responsible for postural hypotension is unclear, but pointers seen in our patients included low serum thyroxine concentrations without the expected raised thyroid stimulating hormone, hyponatraemia, and disproportionately pale facies. Visual evoked potential and contrast sensitivity ...
متن کاملThe ChromaTest, a digital color contrast sensitivity analyzer, for diabetic maculopathy: a pilot study
BACKGROUND To assess the ability of the Chromatest in investigating diabetic maculopathy. METHOD Patients with Type 2 diabetes and no concurrent ocular pathology or previous laser photocoagulation were recruited. Visual acuities were assessed followed by colour contrast sensitivity testing of each eye using Chromatest. Dilated fundoscopy with slit lamp biomicroscopy with 78 D lens was then pe...
