The invention provides minimally invasive microsurgical tools and methods to form an
aqueous humor shunt or bypass for the treatment of
glaucoma. The invention enables surgical creation of a tissue tract (7) within the tissues of the eye to directly connect a source of
aqueous humor such as the anterior chamber (1), to an ocular
vein (4). The tissue tract (7) from the
vein (4) may be connected to any source of
aqueous humor, including the anterior chamber (1), an aqueous collector channel, Schlemm's canal (2), or a drainage bleb. Since the aqueous humor passes directly into the venous
system, the normal drainage process for aqueous humor is restored. Furthermore, the invention discloses devices and materials that can be implanted in the tissue tract to maintain the
tissue space and fluid flow.
