Pressure Monitor
First Claim
1. A sensor comprising:
- a. a body;
b. an adhesion substrate placed on a portion of said body, wherein said adhesion substrate is formed to adhere to the surface of a sclera;
c. a pressure monitoring device affixed to said body and abutting said sclera, wherein said pressure monitoring device measures the intraocular pressure and generates a signal that may be correlated to the measured pressure; and
d. a transmitter affixed to said body, wherein said transmitter transmits said signal from said pressure monitoring device.

Abstract
A sensor and method of use thereof for continuously measuring intraocular pressure (IOP) is disclosed. The sensor is designed to be adhered to the sclera of an eye and may be passive or active, with or without flash memory or other data storage media. The sensor includes a pressure monitoring device that abuts the sclera and generates a signal that may be correlated to IOP. The sensor then transmits this signal to either a receiver in a base unit or to flash memory within the sensor. In exemplary embodiments the pressure monitoring device includes a strain array and/or a resonant circuit, but any pressure monitoring device may be used. In one embodiment the sensor includes a microprocessor unit that controls the other electrical components of the sensor and directly interrogates the pressure monitoring device for a each IOP measurement.
