1. An ophthalmic device for measuring relative pressure of fluid inside an ocular globe, the device being of the type adapted to cooperate with a fluid transfer means which is located external of the ocular globe and capable of supplying or removing intraocular fluid in response to predetermined signals, the device comprising:

  • (a) an elongated surgical instrument adapted to penetrate the ocular globe;

    (b) pressure sensitive means mounted on the instrument for moving in response to relative pressure changes in intraocular fluid;

    (c) transducer means communicating with the pressure sensitive means for generating signals in response to movement of the pressure sensitive means;

    (d) signal means for transmitting signals to the fluid transfer means; and

    (e) first conduit means operatively connected between the fluid transfer means and the interior of the ocular globe so that fluid can be supplied to or removed from the ocular globe in response to said signals.
