Abstract
An acoustical tonometer having an ocular chamber in which a target eye is positionable, a drive chamber containing an acoustical generator and an inertia tube connecting the two chambers. Sound waves produced in the drive chamber are used to excite the target eye. The behavior of the eye on the resonant response of the system is used to determine the health of the eye.
