Claim:
An implantable drain for venting fluid from the anterior chamber of an eye comprising: a shunt having a first end and a second end and a passageway therethrough; said first end of said shunt adapted to engage within the anterior chamber of an eye; a conduit having a sidewall running between a first end and a second end, said conduit having an axial passage running therethrough and communicating with said first end; a plurality of apertures communicating through said sidewall with said axial passage; means for a removable sealed engagement of said first end of said conduit with said second end of said shunt; said sealed engagement connecting said passageway with said axial passage; and said conduit adapted for mounting within a space formed in the plane formed by the scleral layer of said eye, whereby fluid from said anterior chamber communicated to said scleral layer when said shunt is engaged with said anterior chamber; said conduit having a beginning at said first end of said conduit and to a serpentine shaped portion; said serpentine portion formed by a plurality of segments of said conduit traversing back and forth across an axis extending from said first end to said second end of said conduit; said serpentine portion having a plurality of said apertures therein; said serpentine portion and said neck portion combining to yield a total aggregate length of said conduit which is longer than a first length of said conduit running along a line directly between said first end and said second end; and said aggregate length providing means to place a longer conduit within said sclera within a space in said sclera adapted in a length of said space to house a said conduit of said first length therein.
