Embodiment Construction

[0022] In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the subject technology. It should be understood that the subject technology may be practiced without some of these specific details. In other instances, well-known structures and techniques have not been shown in detail in order not to obscure the subject technology.

[0023] As noted above, glaucoma filtration surgery often results in an undesirably low intraocular pressure in the anterior chamber of the eye, and often results in hypotony. The present disclosure provides various embodiments of methods and devices that, by regulating flow through an intraocular shunt, enable the clinician to substantially prevent post-glaucoma filtration surgery while enabling the clinician to ensure adequate pressure relief. low intraocular pressure. As used herein, the term "shunt" includes hollow microfistulas (of the type generally described in US Patent N...

Abstract

An implanted intraocular shunt can be manually manipulated, without surgical intervention, to modify the flow resistance of the shunt, thereby providing relief from high intraocular pressure while avoiding hypotony. For example, through the application of pressure along a surface of the eye, a portion of the shunt can be displaced or separated relative to the shunt, thereby decreasing the flow resistance of the shunt.

Description

Background technique [0001] Glaucoma is an eye disease that affects millions of people. Glaucoma is associated with increased intraocular pressure due to a malfunction in the eye's drainage system that fails to adequately remove aqueous humor from the anterior chamber of the eye or due to excessive production of aqueous humor by the ciliary body in the eye. The buildup of aqueous humor and the resulting intraocular pressure can cause irreversible damage to the optic nerve or retina, which can lead to irreversible retinal damage and blindness. [0002] Glaucoma can be treated in many different ways. One treatment modality involves the delivery of drugs, such as beta-blockers or prostaglandins, to the eye to reduce the production of aqueous humor or to increase the outflow of aqueous humor from the anterior chamber of the eye. Glaucoma filtration surgery is a surgical procedure typically used to treat glaucoma. This procedure involves placing a shunt in the eye to relieve pre...
