Neueste Erkenntnisse aus Biomechanik und Klinik ermoeglichen eine computerunterstutzte Darstellung der Augenmotilitat von Schielen und komplexen Augenmotilitatsstoerungen. Die biomechanischen Faktoren und die grundsatzlichen Operationsmethoden werden aufgezeigt. Die funktionelle Anatomie des Augenbewegungsapparates und dessen zentraler Steuerung, die anschauliche Beschreibung einfacher mathematischer Grundlagen der Okulomotorik und biomechanischer Augenmodelle, die Darstellung einer "funktionellen Topographie" als Orientierungshilfe fur die Diagnostik und Simulation stehen im Mittelpunkt. An Beispielen werden parallel klinische und biomechanische Gesichtspunkte der Messung, Differentialdiagnostik und Simulation horizontaler und vertikaler Motilitatsstoerungen besprochen. Ein interaktives Computerprogramm (SEE++) zur Simulation von Motilitatsstoerungen sowie deren operativer Korrektur liegt als CD bei. Ein umfangreiches Literaturverzeichnis sowie zahlreiche Abbildungen und Tabellen vervollstandigen das Buch.

The goal of this work was the development of a biomechanical model of the human eye. The research work SEE-KID (Software Engineering Environment for Knowledge based Interactive Eye motility Diagnostics), described in this work, tries to connect aspects of biomechanical modelling with methods of modern Software Engineering. An interactive software system was implemented, called SEE++ which allows physicians to obtain a better understanding of the mechanics of eye movements. This software visualizes and simulates pathologies and eye muscle surgeries, based on the biomechanics of the eye. It can be used in preoperative planning, medical training and basic research, and shows how Medical-Informatics can improve the diagnosis and treatment of patients. The project SEE-KID is based also on the software system Orbit (www.eidactics.com) and on other biomechanics software. The SEE-KID project and the SEE++ software system are meant as extension to Orbit with more clinical relevance while providing essential functionality similar to what Orbit offered. Additionally, SEE-KID tries to extend existing functionality and combine different aspects of modelling into one single system.

The authors have developed a computer program that can be of valuable assistance in surgical decision-making for strabismus surgery. The combination of diagnostic data of individual surgical cases, related diagnosis and treatments are incorporated into a well designed, clinically applicable software system. A new way of interactive, virtual eye muscle surgery and preoperative planning is proposed, based on a biomechanical model of the human eye, which enables the prediction of surgical outcomes on the basis of objective, anatomically related and measured data. Additionally, a realistic three-dimensional visualization of the human eyes and their muscles is used to support detailed evaluation and meaningful interpretation of eye motility disorders. This software system is not intended to replace common clinical diagnostics, nor surgical expertise but it should improve the accuracy of clinical decisions in an objective manner.
