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.
