Abstract

In this paper, a three-dimensional finite element method is developed to simulate the heat distribution in the human eye with different types of tumors to understand the effect of tumors on heat distribution in the human eye. The human eye is modeled as a composition of several homogeneous regions and the physical and thermal properties of each region used in this study are more accurate than the models used in previous studies. By considering the exact and complicated geometry of all parts, the finite element method is a proper solution for solving the heat equation inside the human eye. There are two kinds of boundary conditions called the radiation condition and the Robin condition. The radiation boundary condition is modeled as a Robin boundary condition. For modeling eye tumors and their effect on heat distribution, we need information about eye tumor properties such as heat conductivity, density, specific heat, and so on. Thanks to no accurate reported information about eye tumor properties, the properties of other types of tumors such as skin, and bowel tumors are used. Simulation results with different parameters of eye tumors show the effect of eye tumors on heat distribution in the human eye.
