Apparatus and method for self-measurement of intraocular pressure
First Claim
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.

Abstract
An apparatus and method for the self-measurement of intraocular pressure utilize a tonometer disposed within a housing and having a tonometer tip. The apparatus further includes an adjustment mechanism in communication with the tonometer for positioning the tonometer tip in contact with a test eye of the user, and an illuminator mounted within the housing adjacent the tonometer tip. A receiver is aligned with the tonometer tip for receiving an applanation pattern created by contact of the tonometer tip with the test eye, and a display is provided in communication with the receiver for displaying the applanation pattern to an observing eye of the user. 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.

10. A hand-held apparatus for the self-measurement of intraocular pressure by a user having a test eye and an observing eye, the apparatus comprising:
-
a housing having a first ocular portion and a second ocular portion on one side thereof; a tonometer disposed at least partially within the first ocular portion 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 disposed within the first ocular portion and aligned with the tonometer tip for receiving an applanation pattern created by contact of the tonometer tip with the test eye; and a display disposed in the second ocular portion and in communication with the receiver 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. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)

20. A method for the self-measurement of intraocular pressure by a user, the method comprising:
-
providing a housing having a tonometer disposed therein, the tonometer having a tonometer tip; placing a test eye and an observing eye of the user adjacent to the housing; illuminating the test eye; positioning the tonometer tip in contact with the test eye; receiving an applanation pattern created by contact of the tonometer tip with the test eye; displaying the applanation pattern to the observing eye; and determining the intraocular pressure of the test eye based on the force applied by the tonometer tip upon observation of a selected applanation pattern by the observing eye. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27)
