Automated Segmentation of Hard Exudates Using Dynamic Thresholding to Detect Diabetic Retinopathy in Retinal Photographs
Retinal images are in use by ophthalmologists for the clinical analysis and diagnosis of different retinal diseases. The ocular disease known as Diabetic Retinopathy (DR) is a retinal disease that causes microvascular changes in the eye retina. Hard Exudates (HE) a retinal lesion can be seen as bright yellowish spots in colored fundus photograph and as bright white blobs in red free fundus imag...
متن کاملComments on Retinal Sensitivity Over Hard Exudates in Diabetic Retinopathy
455 Dear Editor, We read with interest the article “Retinal Sensitivity over Hard Exudates in Diabetic Retinopathy” by Raman et al.[1] The authors analyzed 12 eyes with diabetic retinopathy with hard exudates using microperimetry. They found reduced retinal sensitivity in the areas of hard exudates which correlated negatively with retinal thickness, but not with the size of exudation. We would ...
متن کاملRetinal Sensitivity over Hard Exudates in Diabetic Retinopathy
PURPOSE To evaluate retinal sensitivity over hard exudates in correlation with the spectral domain optical coherence tomography (SD-OCT) findings in eyes with diabetic retinopathy. METHODS Twelve eyes of 10 patients with hard exudates associated with diabetic retinopathy were enrolled in this study. All subjects underwent a complete ophthalmic examination including SD-OCT (Copernicus, Zawierc...
متن کاملAutomatic Exudates Detection from Non-dilated Diabetic Retinopathy Retinal Image Using Fuzzy C-means Clustering
Exudates are the primary signs of diabetic retinopathy which are mainly cause of blindness. It could be prevented with an early screening process. Pupil dilation is required in the normal screening process but this affects patients’ vision. Automatic computerized screening should facilitate screening process, reduce inspection time and increase accuracy. In this paper we proposed an automatic m...
متن کاملRetinal image analysis based on mixture models to detect hard exudates
Diabetic Retinopathy is one of the leading causes of blindness in developed countries. Hard exudates have been found to be one of the most prevalent earliest clinical signs of retinopathy. Thus, automatic detection of hard exudates from retinal images is clinically significant. In this study, an automatic method to detect hard exudates is proposed. The algorithm is based on mixture models to dy...
