Abstract

Age-Related MACULAr Degeneration (AMD) is the second disease diabetes which causes blindness in aged people. The only remedy for AMD is intravenous injection of bavecizumab. To prove the efficiency of remedy, the degenerated cells in MACULA should be measured. In this article, a modern system is introduced to measure Auto-Fluorescence in MACULA part of retina in order to obtain number of degenerated cells. The system consists of three main parts: Preprocessing stage is omission of margins and reversion of images in retina. Analysis stage is in charge of classification of images and elicitation of their features. In classification the target areas are identified by methods like MORPHOLOGY, dynamic threshold and CONNECTED COMPORTMENTS and the features of target area including Euclidean distance to the center of image and density. In the stage of understanding by gathering the features of each class, we will get the measurable parameter of evaluating Auto Fluorescence by the help of which we can count the number of degenerated cells of MACULA area. The results are coming from statistical analysis, including linear regression and correlation of data.Experiments have been done on a database of 34 RETINA IMAGES of AMD patients. The average statistical error rate is equal to76 percent. In clinical reviews, the founded relation to disinflation of MACULA has been proved, while there were no proved relations to the vision decreasing or increasing of patients.
