Middle East Afr J Ophthalmol. 2015 … WebNov 5, 2024 · Measuring corneal hysteresis, or CH, is the next evolutionary step in the process of understanding this. CH is much more than a measure of thickness—it’s a measure of the shock-absorbing capacity of the cornea, and hence, the shock-absorbing capacity of the eye. (A high level of hysteresis means the cornea has a large capacity for …

WebCorneal Hysteresis has consistently shown to be a more powerful predictor of, and strongly associated with, glaucoma progression, more so than key risk factors such as IOP and CCT. IOPcc is a pressure measurement that is less affected by corneal properties and more associated with glaucoma risk than Goldmann and other tonometers. st. lucia island resortsWebIn addition, hysteresis may enhance intraocular pressure (IOP) interpretation: low corneal hysteresis is associated with a larger magnitude of IOP reduction following various glaucoma therapies.
