Abstract: Some embodiments of the system described herein provide non-invasive intraocular pressure monitoring throughout an extended period. Such monitoring systems can be used for the diagnosis and management of glaucoma patients and those at risk for glaucoma. In some embodiments, the monitoring system provides intraocular pressure monitoring in the patient's normal environment without the need to house the patient in a sleep laboratory.

Abstract: A bioinert implantable shunt device useful for controlling internal pressure includes a valve apparatus, a device for attaching the valve apparatus and an inlet tube. The valve apparatus includes an inlet port, an outlet port, a flexible tube connected therebetween and a pressurized enclosure. The flexible tube is positioned inside the pressurized enclosure whereby fluid flow from the inlet port to the outlet port is dependent on a differential pressure between a pressure in the flexible tube and a pressure outside the flexible tube in the pressurized enclosure. The inlet tube is connected to the inlet port of the valve apparatus. The pressurized enclosure may include a housing and a semi-permeable membrane in a wall of the housing whereby fluid can pass through the semi-permeable membrane into the pressurized enclosure thereby increasing the pressure in the pressurized enclosure. The implantable shunt device may be for use in the treatment of glaucoma.
