Abstract :
A feasibility study on an intraocular magnetic sensor for continuous monitoring of the pressure inside the eyes is introduced. In this first approach the system consists on a coil designed for special goggles and on a small cylinder of magnetic material aimed at simulating the magnetic sensor. The analysis has been carried out from both an experimental and theoretical point of view. In particular perturbative methods have been adopted for evaluating the inductance variation. Results from measurements have shown a good agreement with theory and they appear to be encouraging for further studies.
