Abstract
There are many eye infections and eye diseases like Diabetic Retinopathy, Glaucoma, Age-related Macular Degeneration, Cataract, etc., which cause eye blindness. Glaucoma is one of the major eye diseases that can cause complete blindness. According to National Eye Institute (NIH), there are 2.72 million people are suffering from Glaucoma in the U.S. The primary cause for Glaucoma is higher Intraocular Pressure (IOP), so detecting IOP in the early stages is a vital aspect in the assessment of patients at hazard from glaucoma. The instrument used to measure IOP is called Tonometer and usually used for clinical purposes. However, some part of the Glaucoma research in the research labs tonometer is not practical. Therefore, there is a need to design and develop an IOP measuring device. This device should also have additional features to save the experimental data for later analyzing. Therefore, the primary objective of the current work is to design, develop, assemble, and to validate an electronic measuring device that would help the research on an eye in particular Glaucoma. As a thesis study work, we have designed and developed a measuring device, which can show the real-time sensor data with a Graphical User Interface. The IOP measuring device uses commercially available disposable blood pressure sensor (5uV/V/mmHg), to measure IOP. The IOP device has self-calibration feature to offset any measurement errors due to elevation changes, or errors due to changes sensor sensitivity. In addition to that, the device has a 4x20 (4 lines 20 characters) LCD that shows basic measurement results in addition to external VGA display. It is a very useful feature if there is no external VGA monitor available. Finally, the device has the capability to save the data into Universal Serial Bus (USB) drive for later analyzing the data.
