1. An apparatus for draining aqueous humor from an eye for reducing intraocular pressure, the eye having an anterior chamber and including a cornea, a surrounding marginal limbus by which the cornea is continuous with a scleral layer and a conjunctival layer, and an exposed ocular surface of the eye and under eyelids, the draining apparatus comprising:
a tube extending between an inlet end configured to be disposed at the anterior chamber of the eyeball and an outlet end, the tube defining a passage for fluid flow between the inlet end and the outlet end; and an outlet assembly having an inner surface and an outer surface and configured to be disposed such that the inner surface contacts the conjunctival layer externally of the eyeball, the outlet assembly comprising
a housing defining a cavity in fluid communication with the outlet end of the tube and having an aperture opening into the cavity for allowing egress of aqueous humor onto the external ocular surface,a resistive component disposed in the cavity of the housing between the outlet end of the tube and the aperture, the resistive component configured for providing resistance to a flow of aqueous humor for controlling the flow through the tube from the anterior chamber of the eyeball to the external ocular surface, anda pair of tabs projecting outwardly in opposite directions from the housing, the tabs adapted to be disposed subconjunctivally for securing the draining apparatus relative to the eyeball. |
