Download or read book Intravitreal Steroids written by Albert J. Augustin and published by Springer. This book was released on 2015-02-19 with total page 113 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explains how to use intravitreal steroids optimally in the management of patients with intraocular inflammation (uveitis) and macular edema. The rationale for this treatment approach is first explained by examining the pathophysiology of these disease entities, with particular attention to the major role of inflammatory processes. Devices for the delivery of steroids to the eye are discussed, and guidance provided on the role of imaging studies before, during, and after steroid therapy. The value of different steroidal approaches is then considered in detail. Other topics addressed include the use of steroids as a surgical adjunct and within a combination strategy. Uveitis and macular edema are common sight-threatening diseases or complications of diabetes and retinal vein occlusion for which no adequate treatment was available until recently. Both trainees and practitioners will find Intravitreal Steroids to be an invaluable aid in combating these blinding diseases.
Download or read book Diabetic Retinopathy written by S. Riaskoff and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: The evaluation of diabetic retinopathy is often difficult, because the clinical picture is complex due to the mUltiplicity of symptoms. Omission of treatment by photocoagulation at the right moment may have grave consequences. Forthe evaluation of diabetic retinopathy we have to estimate first the developmental degree of each symptom and secondly we have to estimate what the natural history of each particular retinopathy will be. There exists a number of classification systems, into the frame of which the clinical picture of diabetic retinopathy can be placed. Without entering into the details of these systems we want to mention that our classification has been developed from the method of Oakley and the classification model conceived at the Airlie House meeting in 1968. The essence of this classification is that standard pictures are used for the estimation of the developmental degree of the different symptoms in diabetic retinopathy. In our classification we use for each symptom two standard photographs instead of one, as originally proposed at the Airlie House meeting. (1,2). Standard photograph number one stands for the moderate (grade 1 ) manifestation and standard photograph numbertwo stands forthe marked (grade 2) manifestation of the symptom. Ifthe manifestation ofthe sympton is less marked than in standard photograph one, it is referred to as 1 ; if it is more marked than in standard photograph two, it is referred to as 2.

Download or read book Retinal Image Processing for Automated Detection and Grading of Diabetic Retinopathy written by Hussain Fadhel Hamdan Jaafar and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The main eye condition associated with diabetes is called diabetic retinopathy and is, the main cause of blindness. The earliest signs of this disease include damage to retinal blood vessels and then the formation of lesions such as exudates and red spots. Such lesions are normally detected manually by clinicians in intensive and time-consuming processes. Computer:--aided detection and grading of such conditions could facilitate an immediate and accurate Criagnosis. Whilst some progress has been made to detect these diseases, there is no complete system for automated detection and grading of diabetic retinopathy and this is hindering the development of automated methods to support assessment of diabetic eye disease. The aim of this work is to develop computer algorithms that can be used in the medical screening system for evaluating the condition of the retina leading to successful treatment. This work comprises five stages: 1) image pre-processing, 2) retinal structure extraction; 3) hard exudate detection, 4) red lesion detection and 5) grading of diabetic retinopathy. The aim of image pre-processing is to prepare the image with better quality where shade correction using morphological processes and contrast enhancement using fuzzy logic-based method are applied to the image. In the retinal structure extraction, multi-scale morphological technique and classification procedure are proposed for blood vessel detection. Vasculature loop-based method for the optic disc localisation is proposed, while for fovea localisation, a method based on its features and geometric relationships with the other retinal structures is developed. These methods have the advantage of lower computational complexity and competitive performance compared to the existing related methods. A novel coarse to fine strategy is proposed to detect hard exudates, where a local variation operator is used to calculate the standard deviation around each pixel followed by automated thresholding, morphological operations, and classification to segment coarse hard exudates. To fine-tune the result of coarse hard exudates, two region-based segmentation techniques are investigated to detect fine hard exudates. The significance of this method is manifested by its superior performance, lower computational complexity (compared to the current state of the art) and the ability to deal with a variety of image qualities. A novel red lesion detection method is proposed using mathematical morphology to segment candidate red lesions followed by refining them from traces of retinal structures and then a classification based on red lesion features is used to detect red lesions with high degree of discrimination between genuine red lesions and artifacts and as a result its detection performance has proved to be favourable. Grading of diabetic retinopathy is a very important stage after the detection of retinal lesions to evaluate their severity and to decide appropriate treatment. The most reliable medical approaches to diabetic retinopathy grading were investigated to build a novel computer-aided model for automated grading based on the clinical criteria and results of the earlier lesion segmentation. This model quantifies the nature, extent and spatial distribution of all the detected features and provides a clinical grading assessment. This is among the first of such models published and as such the novelty is considered to be one of the main contributions of this thesis.

This book was released on 2006 with total page 49 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diabetes mellitus is an important public health problem worldwide, and more than 75% of patients who have had diabetes mellitus for more than 20 years will have some sort of retinopathy. Diabetic retinopathy correlates with the duration of diabetes; thus with increasing life expectancy, diabetic retinopathy and the ensuing blindness will tend to increase. In view of the increasing prevalence of diabetes mellitus and diabetic retinopathy throughout most of the world, a consultation on prevention of blindness from diabetes mellitus was convened by the World Health Organization to review the current status of diabetic retinopathy care and to define approaches to screening, early detection and management in populations in different settings. This publication reports on the findings of the consultation and provides recommendations and guidelines for the prevention and care of blindness from diabetes mellitus.
