I incorporated corneal hysteresis (CH) measurement into my clinical practice more than 7 years ago. My experience with CH and the published data on the biomechanics of the eye continue to show that CH is a vital sign of glaucoma. I depend on this value to help me individualize the care of each patient and to further risk-stratify glaucoma patients and glaucoma suspects. In fact, I do not make a clinical decision about a patient with glaucoma or a glaucoma suspect without knowing their CH value.

This article provides an update on recent studies demonstrating the clinical utility and importance of CH, corneal-compensated IOP (IOPcc), and the biomechanics of the eye as they pertain to glaucoma development and progression. Additionally, a case report shows how I used this information to care for a patient ...
