Synthesizing images of the eye fundus is a challenging task that has been previously approached by formulating complex models of the anatomy of the eye. New images can then be generated by sampling a suitable parameter space. In this work, we propose a method that learns to synthesize eye fundus images directly from data. For that, we pair true eye fundus images with their respective vessel tre...
The paper address the problem of retinal image segmentation, and aims at describing a novel segmentation technique, based on the watershed algorithm, able to separate in a clear way blood vessels from background. Automatic accurate analysis and quantitative characterization of diagnostically relevant features of retinal images can help clinicians for diagnosis and follow-up of eye diseases.
Introduction: Age-related macular degeneration (AMD) is one of the retina diseases in which retinal pigment epithelium cells are degraded and lead to blindness. Available treatments only slow down the progression of it. In this study, human embryonic stem cells (hESCs) differentiated into retinal pigment epithelium cells were cultured on a polycaprolactone scaffold. Methods: The optimization o...
Introduction: Degenerative retinal diseases are main cause of irreversible blindness. Stem cells therapy is a promising way in these diseases. Therefore, mesenchymal stem cells because of its safety can produce degenerated cells and can play important role in treatment. The aim of this study was to examine morphological changes in injured retinal pigment epithelium (RPE) and photoreceptor cells...
