Abstract
Glaucoma is a serious disease, affecting millions of people worldwide requiring continuous monitoring of Intra Ocular Pressure (IOP) to avoid the risk of blindness. Current laboratory measurements are infrequent, intrusive and do not indicate the progression of the disease. The paper reports on the development of an implantable Glaucoma monitoring system that can monitor IOP in the eye to indicate any elevation in risk to the patient. A mathematical model of the anterior chamber of the eye was used to analyze the complex fluid flow and pressure balance in the eye. This was done in order to determine the performance requirements of the actuator, sensor and transmission electronics that could be integrated on a single microchip using microelectromechanical systems (MEMS) technology, to carry out the testing internally. The accuracy of the system was theoretically tested against results from external medical tests. The results were found to be comparable.
