 Abstract: Described is an eye monitoring device (300) for inductive orientation measuring on an eye (2) of a proband (1), in particular for use in combination with a magnetic resonance tomography unit (200), wherein said eye monitoring device (300) comprises: a transmitting device (320, 310) which is adapted for generating a magnetic field which changes over time, with which magnetic field an induction voltage can be induced in a receiving device (310, 320); a generator device (330) for generating at least one excitation voltage for the transmitting device (320, 310); and a signal processing device (350) for processing induction voltage signals of the receiving device (310, 320), wherein one of the transmitting or receiving devices comprises an eye coil device (310) with an eye coil (311) which can be connected to the eye (2) and which is movable with said eye (2), while the other one of the transmitting or receiving devices comprises a visual-field coil device (320) with at least one visual-field coil (321, 322) which is smaller than the head (3) of a proband (1) and which is equipped during the process of measuring to be arranged so as to be fixed in front of the eye (2), adjacent to a field of view of said eye (2). Also described is an examination device which comprises an eye monitoring device for inductive eye-orientation measuring, as well as a magnetic resonance tomography unit.
