The Research On Physical Modeling Of The Human Eyeball And The Biomechanical Analysis With Application To Glaucoma

The parametric modeling of human body and human apparatus and the emulational research based on these models are the foreland of biomedicine all over the world. Eye is one of the most complex and important part of all human apparatus. So the modeling of human eye and the research based on the models are significative. To constitute a system of"virtual human eye", which can work just like the real one, the Geometrical model of human eye must be built firstly, then the Physical model, in which all the parts can have their own physical properties, at last Functional model will be set up, which can simulate the function of human eye.With the method of"From Simple to Complicated", a set of 3D-parametric geometrical models of human eye were established in this paper based on reasonable hypothesis and predigestion. The Finite Element Analysis tool——"ANSYS"was adopted here when modeling. And the medicinal clinical data of human were used as the input parameters. The Physical model was established by meshing, in which the Geometrical model could be dispersed in limited numbers of small segments with the properties of corresponding tissue of human eye. Based on the hypothesis, predigestion, the displacement loading and pressure loading were applied to the models according to the object of this research——"glaucoma". Solved with finite element method, the models can result in the resolutions of the contour of all the Nodes'displacement, which could be helpful for the research of the clinical symptom of glaucoma.It is only the element research of the physical modeling of human eye described in this paper. And the models established here can be used in the analysis. All the results and attempts could benefit the lucubrate of this area. Followings are some main innovations in this thesis:Established a set of parametric 3D physical models of human eye, which1. make it possible that the system of"Virtual Human eye"can be applied to the biomechanical analysis. Because the structure and Physical attribute of human eye is very intricate, it is necessary to make hypothesis and predigest before establishing the models. Different models are established on the base of different hypothesis and...
