APPLICATIONS OF INFORMATION TECHNOLOGIES FOR RESEARCH IN CLINICAL OPHTHALMOLOGY A.Paunksnis1,2, S.Kurapkienė1,2, V.Barzdžiukas1,2, A.Lukoševičius3, G.Dzemyda4 1 Telemedicine Center of Kaunas University of Medicine, 2Dept. of Ophthalmology of Institute for Biomedical Research of Kaunas University of Medicine, 3 Kaunas University of Technology,, 4Vilnius Mathematics and Informatics Institute, Lithuania [email protected] Lithuania is implementing the eHealth strategy by the pilot national projects creating the common structure and R&D components of the integrated national eHealth system [2]. The main targets of applications of information technologies for research in clinical ophthalmology are images (optical and ultrasound data) and signals (ultrasound data) - the most informative sources for differential diagnosis [1, 3, 4]. The main activities: Registration and parametrization of diagnostic signals and images, selection of most informative parameters, creation of databases and interfaces; Data mining in data bases and clinical decision support using learning algorithms, remote access to services and expertise of physicians. Development of prognostic, diagnostic and treatment recommendations using the knowledge portals created. Results: Methods and software for eye fundus images parametrization – including automatic recognition of optical nerve region, automatic outlining of this region and calculation of geometric parameters of the optical nerve and excavation. Calculation of the set of parameters reflecting the diagnostically important eye fundus features. The method of excluding of the network of blood vessels from fundus image was developed enabling to improve diagnosis of retinal damages. The methodology for ultrasonic diagnostic information registration and collection created, the effective processing methods and algorithms created and improved, quantitative ultrasonic diagnostic parameters calculated and their functional relation with other parameters and tasks of clinical ophthalmological practice evaluated.
