A device used to measure intraocular pressure within a patient's eye includes
a
probe typically having an end to which is attached a resilient member with a hollow
interior that decreases in volume as the member is pressed against the eye. The
greater the intraocular pressure within an eye, the more the volume decreases.
A liquid moves in response to this change and this movement is detected to signal
if the intraocular pressure is at a safe level.
