1. An apparatus for the self-measurement of intraocular pressure by a user having a test eye and an observing eye, the apparatus comprising:

  • a housing;

    a tonometer disposed within the housing and having a tonometer tip;

    an adjustment mechanism in communication with the tonometer for positioning the tonometer tip in contact with the test eye;

    an illuminator mounted within the housing adjacent the tonometer tip;

    a receiver aligned with the tonometer tip for receiving an applanation pattern created by contact of the tonometer tip with the test eye; and

    a display in communication with the receiver and oriented toward the user for displaying the applanation pattern to the observing eye,wherein the intraocular pressure of the test eye is determined from a force applied by the tonometer tip upon observation of a selected applanation pattern by the observing eye.
