This project deals with new therapeutic options for glaucoma. Glaucoma is the second most common cause of blindness in the world, and there is currently no treatment available. In a large proportion of those affected, increased internal pressure in the eye poses a risk for the development of glaucoma. The goal of this project is to develop an intraocular pressure sensor and regulator for glaucoma, that can minimize medical intervention and revision surgeries. Empa researchers, together with the Department of Ophthalmology at the Animal Hospital in Zurich, are developing a self-regulating system consisting of a tiny, highly sensitive sensor that can normalize intraocular pressure by allowing drainage of the chamber fluid in the eye via a valve made of a biocompatible hydrogel.
