the ambient pressure is within a predetermined range as shown in fig2 b as is well known by those of skill in the art the random motion of the eye is continuous and slight pressure fluctuations are constant in the case of an ocular implant the range of nominal pressure would be the normal pressure range for a normal human eye if the ambient pressure is above the predetermined range the bladder sidewalls 22 with the appropriate thickness and flexibility as discussed above will become inwardly deflected as shown in fig3 and 4 fluid will flow as indicated by arrows 60 from the bladder 20 into and through discharge conduit 38 to the distribution plate 70 discharge conduit 38 may be connected to an additional conduit not shown to pump fluid away from the implant area to the back of the eye and over the distribution plate 70 note that the combination of conduit 77 and distribution plate 70 in a way act like the traditional valves such as the ahmed valve u s pat no 5 785 674 baerveldt u s pat no 5 476 445 krupin u s pat no 5 454 796 or molteno u s pat no 4 570 901 however these valves are passive shunts and create a scar tissue bleb which forms around the assembly often occluding the opening of the drainage conduit and rendering the device non functional the present invention provides an active continuously pumping aqueous humor and is thus unlikely to allow any bleb to form the discharge conduit 38 may also include a widened end.
