Abstract

Most patients with glaucoma exhibit elevated intraocular pressure (IOP). A cost effective device that allows the patient to measure IOP at regular intervals may reduce vision loss. This research tested the Bausch & Lomb Proview self tonometer against a calibrated force meter. It further compared the Proview tonometer with results from the clinical gold standard, the Goldmann tonometer. Results show that the Proview tonometer has inaccuracies in calibration and uncertainties in clinical applications. If the Proview's calibration is corrected (using our results, e.g.), and the inaccuracies can be reduced, a device like the Proview has the potential to be clinically useful.
