Fig. 1: Schematic illustration of uveal melanoma detection with EIS.
From: Evaluation of electrical impedance spectroscopy of bovine eyes for early detection of uveal melanoma
a Two electrodes are placed on cornea and the current flows from electrode to the eye and return to the second electrode. The presence of tumors in uveal tract changed the current density in eye, b The equivalent circuit of the biological tissues. Low frequency currents flow through intercellular fluid and high frequency currents flow through cells.
