Optical Coherence Tomography, OCT, is a relatively recent imaging technique that allows high resolution imaging of the retina. It relies in certain optical characteristics of light to provide information of the eye fundus, facilitating the diagnosis of certain eye pathologies. Our goal is to build a mathematical model that describes the electromagnetic wave's propagation through the eye's structures, using Maxwell's equations, in order to create a virtual OCT scan. With this virtual exam, we will be able to test different characteristics of the medium and assess their effect on the final image.
