1. A hand held portable tonometer device for monitoring the intraocular pressure in an eye through the sclera, comprising:

  • a tubular frame having an axis and forming a handle, said handle including pressure transducer means for generating intraocular pressure measurements, said transducer means including scleral probe means for scleral indentation;

    biasing means for positioning said transducer means along said axis and for permitting movement thereof along said axis in response to pressure applied by urging said scleral probe means against the sclera;

    contact means at a location along said axis for defining a zone of measurement within which said transducer means must be located to enable measurement of pressure, said zone having limits which correspond to predetermined upper and lower limits of measurable intraocular pressure and for providing a signal when said transducer means is in said zone;

    output means mounted in said frame for displaying measurement of pressure by said transducer means in said zone of measurement upon receipt of said signal.
