The consequences of changes in the oculomotor system on the three-dimensional eye movements are difficult to grasp. Although changes to the rectus muscles can still be approximately understood with simplified geometric models, this approach no longer works with the oblique muscles. It is shown how SEE++, a biomechanical model of the oculomotor plant that(More)
"Grid-Enabled SEE++" is based on the SEE++ software system for the biomechanical simulation of the human eye. "Grid-Enabled SEE++" extends SEE++ in several steps in order to develop an efficient grid-based tool for "Evidence Based Medicine", which supports surgeons in choosing optimal surgery techniques for the treatment of certain eye motility disorders.(More)
SEE-GRID is based on the SEE++ software system for the biomechanical simulation of the human eye. The goal of SEE-GRID is to extend SEE++ in several steps in order to develop an efficient grid-based tool for " Evidence Based Medicine " , which supports surgeons in choosing optimal surgery techniques for the treatment of certain eye motility disorders.(More)
PURPOSE Eye motility disorders with axial high myopia and an enlarged globe are often characterized by a hypotropia of the affected eye, usually referred to as heavy-eye syndrome. Based on an intuitive interpretation of magnetic resonance (MR) images, the cause of the hypotropia has typically been assigned to the rectus muscles. In this study, the(More)
This document describes the functionality of the " SEE++ to Grid Bridge " , which is the initial component of SEE-GRID. SEE-GRID is based on the SEE++ software for the biomechanical simulation of the human eye. SEE++ was developed in the SEE-KID project by the Upper Austrian Research and the Upper Austria University of Applied Sciences. SEE++ consists of a(More)
PURPOSE To simulate and check the plausibility of the proposed mechanisms of X-pattern exotropia and to determine the least invasive surgical method that can be used to treat the disorder. DESIGN Computational supported analysis and retrospective study. METHODS The oculomotor model SEE++ was used to simulate the effects of the different causes that have(More)
We describe an apparatus for measuring scattering length density and structure of molecular layers at planar solid-liquid interfaces under high hydrostatic pressure conditions. The device is designed for in situ characterizations utilizing neutron reflectometry in the pressure range 0.1-100 MPa at temperatures between 5 and 60 °C. The pressure cell is(More)
In the previous phase of the SEE-GRID project, we implemented the "SEE++ to Grid Bridge", via which normal SEE++ clients are able to access and exploit the computational power of the Austrian Grid. This document discusses the theory and the design of a new functionality of the SEE-GRID system called pathology fitting and described its two simple(More)
SEE-GRID is based on the SEE++ software for the biomechanical simulation of the human eye. The goal of SEE-GRID is to adapt and to extend SEE++ in several steps and to develop an efficient grid-based tool for``Evidence Based Medicine'', which supports the surgeons to choose the best/optimal surgery techniques in case of the treatments of different syndromes(More)
Collision and containment detection between three-dimensional objects is a common requirement in simulation systems. However, few solutions exist when exclusively working with deformable bodies. In our ophthalmologic diagnostic software system, the extraocular eye muscles are represented by surface models, which have been reconstructed from magnetic(More)
