Magnetic fields produced by the human eye (invited)

Abstract

The retina and the pigment epithelium of the human eye contain sources of bioelectric currents, which give rise to intra- and extraocular electric current densities. This paper first gives a review on the magnetic fields arising from ocular currents: the magneto-oculogram (MOG) and the magnetoretinogram (MRG). A mathematical model is presented for calculation of the field distributions and a comparison with experimental data is made. Finally results from experiments on motion and light induced changes in ocular magnetic fields are used to determine retinal current densities.
