Biomechanical simulation of eye motility disorders & strabismus surgeries.

The research initiative SEE-KID / CEVD has been dealing with the computer-aided simulation of eye malpositions and their surgical correction for more than 19 years. An essential goal is the development of the software system SEE++ as a new teaching and learning tool, which supports a clear thinking, particularly in the case of complex functional disturbances. In addition to a biomechanical model of the human eye, the software system also offers the simulation of a three-dimensional “virtual patient” in combination with a realistic representation of muscle shape and movement. This enables an interactive simulation of malpositions and eye muscle operations.

In order to further improve the use of the software in teaching and training, the 3D representation of the virtual patient has been continuously developed in recent years and also includes the integration of the brain, as well as a dynamic representation of individual parts of it. Different interaction possibilities for the individual parts of the brain, as well as the possibility to draw in different classifications on the brain surface and to display medical information about them, contribute significantly to a better understanding of the connections between eye and brain. Future research will focus on the further development of the biomechanical model and the simulation of new surgical techniques.

Work on the development of the new “AmblyoCare” application has been underway since 2010. It offers standardized and variable tests for the classic amblyopia treatment methods on the computer in order to better capture additional characteristics of the visual process and thus make the very best of it more usable for everyday life. The flexibility of the software makes daily work with patients much easier. The practical application of AmblyoCare in the clinic takes place in amblyopia diagnosis and therapy and in early visual aid, where it increasingly supplements or even replaces conventional aids such as the nystagmus drum or picture cards.
