Novel micromachined valved glaucoma drainage devices.

In this work two novel valve devices are proposed for treatment of glaucoma. By opening or closing, the proposed valves can be used to reduce high pressures in the eye (hypertony), or prevent low pressures in the eye (hypotony) respectively. These devices work based on the buckling of fluid channel connected to the anterior chamber of the eye. The first proposed valve is fully mechanical while the second proposed device is magnetically driven.
