Elevated intraocular pressure (IOP) is the main risk factor for glaucoma and is currently the only treatable risk factor. IOP is dynamic with regular circadian variations and random short-term and long-term fluctuations. Current glaucoma management is mostly based on single IOP measurements during office visits which may not accurately represent a patient’s 24-h pressure profile. Most of glaucoma patients have their highest IOP outside clinic hours, usually during the nocturnal period. Currently, the only available approach for 24-h IOP monitoring is by using repeated tonometry which is inconvenient, expensive, and does not provide continuous monitoring of IOP. The goal of continuous IOP monitoring is to provide automated 24-h ambulatory recording of IOP. In this article, we review the existing technologies for IOP monitoring and evaluate new innovative methods for continuous 24-h IOP monitoring, including temporary non-invasive and permanent invasive approaches that currently being developed.
