Distribution of miicroanreurisms of the dataset Number and location of lesions for the optimisation of the screening interval in diabetic retinopathy Diabetic retinopathy is a leading cause of blindness in the Western World. The disease is detected by screening which includes visual acuity measurement and fundus photography (Stefansson et al. 2000; Jeppesen & Bek 2004; […]

During this period, the main goal was to go deeper in the analysis of diabetic patients’ images and try to find any possible indications of the early changes of the vasculature. Moreover the writing of a comprehensive review paper helped to go deeper in understanding the underlying mechanisms that affect the auto regulation of the […]

The beginning of this reporting period was mostly devoted to researching background information for my REVAMMAD project. Along with the literature review, my first step in the practical research included the creation of a data structure based on the object oriented programming technique. Recently I started to create a new algorithm which at the first […]

The main goal of my project is to define alternative strategies that can prove to be more efficient and/or cost saving in the detection of diabetic retinopathy. The first step of this process was an extensive literature review in order to gain a comprehensive understanding of the nature of the disease, the risk factors that […]

During this reporting period, I published a paper at the 36th Annual International Conference of the IEEE Engineering in Medicine and Biology Society and gave an oral presentation regarding my work related to retinal image registration and super resolution. Since then, I started working on a ED model of the eye, and a geometrical approach […]

During reporting period, model of the retinal vascular network was improved, network structure was changed fundamentally and made more realistic, mechanical properties of vessel wall were added, as well as autoregulation of vessel diameter. Program for 3D visualization of network structure and dynamics was written. In addition to modeling part of my work, were carried […]

In the first six month working on the REVAMMAD project we developed an automatic algorithm to generate a 3D mesh of the retinal vessels starting from segmented images of retinal fundus from Lincoln University. We also devised an ad hoc fluid structure interaction model for modeling the interaction between blood and vessel wall into the […]

During this reporting period, the first version of the algorithm to segment corneal endothelial cells was developed.  The corneal nerves segmentation algorithm was adapted and tested in mosaic images.

NUMBER AND LOCATION OF LESIONS FOR THE OPTIMIZATION OF THE EXAMINATION INTERVAL IN DIABETIC RETINOPATHYA recent study concluded that it is possible to construct a model for optimising the examination interval during screening for diabetic retinopathy in low-­‐risk patients. However, the model fails to predict the interval for patients in whom the primary assessment recommended […]

Most of the work done during this period has been on researching background information for my REVAMMAD project. Side projects have included work in confocal microscopy related to the detection of features in different layers of the cornea. This work has led to the submission of two abstracts, one of which has already been accepted […]

To approach retinal vascular diseases it is necessary to adopt different strategies to understand the mechanisms of the pathology and transfer that knowledge into practical clinical tools. Vasculature in the retina changes under pathological conditions. However, vessels are not alone and we have to understand the disease as a complex puzzle where every piece has […]

My REVAMMAD project concerns developing analytical models for simulation of blood flow and vascular structural adaptation in retinal microcirculation under physiological and pathophysiological conditions based on anatomical data from the segmentation of imaging data. In order to gain comprehensive insight into relevant mechanisms underlying function of retinal microvascular network, some other tissues in addition to […]

During last 6 months I reviewed a number of technologies that will be used in implementing the data warehouse and evaluation framework. Together with my supervisor, Dr Luca Antiga, we came up with a very exciting and revolutionary architecture of the data warehouse that will utilize state-of-the-art technologies. We addressed one of the biggest technological […]

During this period the main goal was to study the previous and the ongoing research on the early detection of diabetic retinopathy and find all the experiments that have been done until now. At the same time I had to attend a few training events and collaboration meetings at the university of Lincoln with local […]

During this reporting period, I produced an image registration method with sub-pixel accuracy. I employed such method as the first step for already existing super resolution methods, to produce higher quality images from low resolution datasets and submitted a paper. I also started researching on the topic of 3D reconstruction of the eye model employing […]

A novel method for digital curvature estimation has been proposed during this period. A paper has been written and it will be submitted shortly to a journal. This particular area has been investigated since I am working on corneal nerves tortuosity, in collaboration with Harvard Medical School.The problem is to assess image tortuosity and curvature […]
