Abstract

An apparatus for reducing pressure in an anterior chamber of an eye. The apparatus includes an anterior portion configured for implantation through a scleral tunnel such that a leading edge thereof is within the anterior chamber. A plurality of channels are defined through the anterior portion, the channels being open to an external environment of the anterior portion to provide fluid communication between the anterior chamber of the eye and the channels. The apparatus further includes a body portion extending from the anterior portion distal the leading edge of the anterior portion of the apparatus. The body portion is configured for implantation between conjunctival and scleral tissues of the eye. The body portion defines a channel therethrough, the channel being in fluid communication with one or more of the plurality of channels formed through the anterior portion of the apparatus. Occlusion means are disposed in one or more of the channels formed through the anterior portion of the apparatus. Each of the occlusion means has a first position in which flow through the channels formed through the anterior portion is obstructed and a second position in which flow through the channels formed through the anterior portion is not obstructed. The occlusion means is adjustable between the first position and the second position to provide selective control of the flow of aqueous through the apparatus.
