Continuous 24-Hour Monitoring of Intraocular Pressure Patterns With a Contact Lens Sensor

Abstract
Elevated intraocular pressure (IOP) is a major risk factor for glaucoma.1 Goldmann applanation tonometry (GAT) is considered the criterion standard for measuring IOP,2 but its measurements are influenced by central corneal thickness (CCT), corneal biomechanical properties, and scleral rigidity.3,4 The most significant shortcoming of GAT, however, is the static nature of its measurements. Yet, IOP is a dynamic parameter with distinct circadian rhythms that vary among individuals, and single IOP measurements may fail to reflect the true range of an individual's IOP.5,6
