An ocular drainage
system is provided for treating diseases that produce elevated intraocular pressures, such as
glaucoma, wherein the
system includes an implantable device and an external
control unit, the implantable device includes a non-invasively adjustable valve featuring at least one deformable tube and a disk rotatably mounted within a housing, such that rotation of the disk using the external
control unit causes the disk to apply a selected amount of compression to the deformable tube, thereby adjusting the fluidic resistance of the deformable tube and regulating the
intraocular pressure.
