Device and method for glaucoma management and treatment
First Claim
1. An integrated intraocular device comprising:
- an intraocular pressure sensor element;
an antenna element; and
an aqueous humour drainage element, wherein, the drainage element consists of a porous biocompatible material, wherein the porous biocompatible material substantially encases the intraocular pressure sensor element and the antenna element, and wherein the porous biocompatible material comprises substantially spherical interconnected open pores having a mean pore diameter between 20 μ
m and 40 μ
m and is configured to provide isotropic flow paths for draining aqueous humour into tissue.

Abstract
Described herein is a device for glaucoma treatment and monitoring that comprises a combination of an intraocular pressure (IOP) sensor and a glaucoma drainage device. The device comprises an IOP sensor and an inductive antenna mounted within a porous biocompatible material that forms the drainage path. The IOP sensor is mounted in a footplate portion of the device and is mountable in the anterior chamber of an eye. The footplate portion is connected to a body portion that houses the spiral antenna by a neck portion which retains the footplate portion in a suitable position within the anterior chamber. Due to its size, the footplate portion housing the IOP sensor can readily be inserted into the anterior chamber with the body portion housing the spiral antenna located outside of the anterior chamber in a sub-scleral space to disperse the aqueous humour.
