Intraocular Pressure Sensing And Control For Glaucoma Research, Simon Antonio Bello
Intraocular Pressure Sensing And Control For Glaucoma Research, Simon Antonio Bello
USF Tampa Graduate Theses and Dissertations
Animal models of ocular hypertension are important for glaucoma research but come with experimental costs. Available methods of intraocular pressure (IOP) elevation are not always successful, the amplitude and time course of IOP changes are unpredictable and irreversible, and IOP measurement by tonometry is laborious. This dissertation focuses on the development and implementation of two novel systems for monitoring and controlling IOP without these limitations. The first device consists of a cannula implanted in the anterior chamber of the eye, a pressure sensor that continually measures IOP, and a bidirectional pump driven by control circuitry that can infuse or withdraw …
