Biomechanical simulation of eye motility disorders & strabismus surgeries.

For more than 19 years already, the research project SEE-KID / CEVD has been dealing with the computer-based simulation of eye motility disorders and their operational treatment. A major goal here is the development of the software system SEE ++ as a new teaching and learning tool which supports vivid thinking, especially with complex functional disorders.

For this purpose, the software provides a biomechanical model of the human eye, which was developed within the project, as well as a 3D virtual patient with a realistic visualization of the shape and movement of the extraocular eye muscles. On this basis, the system allows an interactive simulation of eye motility disorders and their surgical correction.

In order to further improve the use of software in teaching and training, the 3D representation of the virtual patient has been steadily expanded in recent years. The most recent extensions are the integration of the brain, as well as a dynamic representation of the individual parts of the brain. The multiple ways to interact with the brain parts as well as the possibility to visualize different classifications on the brain surface and retrieve medical information for them essentially contribute to a better knowledge of the anatomical and functional relationship between the eyes and the brain. The future project work will focus on the further development of the biomechanical model as well as on the simulation of new surgical techniques.

Since 2010, a new application called AmblyoCare has been continuously developed. AmblyoCare offers standardized and variable tests on the computer for the classic amblyopic treatment methods in order to better capture additional visual characteristics and thus make them more useful for everyday use. The daily work with the patient is made much easier by the flexibility of the software.

The practical use of AmblyoCare in the clinic is currently being evaluated in Austria in amblyopia diagnosis and therapy and early-stage screening, where it is increasingly supplementing or even replacing conventional devices such as the nystagmus drums or picture cards.

AmblyoCare is registered in the Austrian register of medical devices as an active medical device and can therefore be used as a medical tool for diagnosis and therapy by professionals (without any concerns). To keep the usage of the tool simple and efficient while offering an extensive pool of functionalities at the same time, AmblyoCare gets continuously improved with the help of doctors and users in order to extend the examination possibilities and simplify the user interface.

Furthermore there soon will be a separate version of AmblyoCare which focuses on treatment at home. This version will considerably simplify the usage of the software, leading to a stronger focus on an efficient and successful therapy. New ways are thus created to assure an effective and promising treatment for amblyopia and other visual diseases.

Examiners as well as patients get access to their examination workflows from anywhere at any time and have the possibility to exchange them between each other. The required data gets anonymized and is saved in a database which is protected against unauthorized access by using authentication- and authorization mechanisms.
