SIMULATION OF ACTIVE EYE MOTION USING FINITE ELEMENT MODELLING
Abstract
DYNAMIC SIMULATION OF HUMAN EYE MOVEMENTS CAN SIGNIFICANTLY IMPROVE OUR UNDERSTANDING ABOUT THE VISUOMOTOR SYSTEM AND ALSO MAY BE USED FOR CLINICAL APPLICATIONS. IN THIS STUDY WE HAVE DEVELOPED A 3D FINITE ELEMENT MODEL OF THE EYE ORBIT. THE MAJOR NOVEL ISSUES WHICH ARE CONSIDERED IN THIS WORK ARE USING FINITE ELEMENT METHOD FOR PROPERLY MASS DISTRIBUTION MODELING DURING DYNAMIC SIMULATION AND ACTIVE MOTION SIMULATION BY EMPLOYING MUSCLE ACTIVATION PARAMETER. IN THIS MODELING, EXTRAOCULAR MUSCLES ARE MODELED USING A CONTINUUM CONSTITUTIVE HYPER-ELASTIC ENERGY FUNCTION. SIMULATION RESULTS OF FORCE DUCTION AND ACTIVE MOTION ARE PRESENTED AND COMPARED WITH THE EXPERIMENTAL RESULTS REPORTED IN THE AVAILABLE LITERATURE TO VERIFY THE ACCURACY AND TRUSTWORTHY OF THE PROPOSED MODELING. ORBITAL FAT DEFORMATION DURING EYE MOTION IS ALSO STUDIED THROUGH VARIOUS SIMULATIONS AND COMPARED WITH EXPERIMENTAL RESULTS. FINALLY, THE PROPOSED EYE MODEL AND AVAILABLE EXPERIMENTAL DATA ARE EXPLOITED TO INVESTIGATE MORE DETAILS ABOUT EYE SUSPENSION DEFORMATION AND EXTRAOCULAR MUSCLES CHARACTERISTICS.
