Abstract

In this paper, mathematical model of the electric and magnetic in the eye volume conductor will be developed. Eye volume conductor is assumed consist of six layers where each of layer is homogen. Each layer is solved numerically by linear trianguler finite element method (FEM) and simulated with Matlab 5.31. From the simulation result indicate that electric potential distribution of the outer extraoculer (radius 49 mm) has the maximum value 3.4 × 10^-4 mV, the maximum magnetic field is 1.07 × 10^-14 mTesla. In the layer aqueous and vitreous humor (radius 6.75 mm) has the maximum electric potential 7.4 × 10^-2 mV and the maximum magnetic field is 1.8 × 10^-12 mTesla. The distribution in the other radius and variation of the conducting medium is achieved too.
