Intraocular pressure sensor with external pressure compensation

摘要

An intraocular pressure sensor system has a first pressure sensor located in an anterior chamber of an eye and a remote pressure sensor located remotely from the first pressure sensor. The remote pressure sensor measures or approximates atmospheric pressure. A difference between readings from the first pressure sensor and the remote pressure sensor approximates intraocular pressure.

1. A glaucoma treatment device comprising:
an end cap with proximal and distal ends; an anterior chamber pressure sensor integrated with and located at the proximal end of the end cap and in fluid communication with an anterior chamber of an eye; a remote pressure sensor, the remote pressure sensor measures or approximates atmospheric pressure, the remote pressure sensor integrated with and located at the distal end of the end cap and under a conjunctiva of the eye; and a tube with proximal and distal ends, the tube fluidly coupling the anterior chamber to a location outside the anterior chamber wherein the end cap is located in and seals the distal end of the tube; wherein the end cap is configured to be located in the eye.
