VIDEO: Corneal hysteresis value aids glaucoma detection, management
LAS VEGAS — Corneal hysteresis is an objective measurement that can help clinicians diagnose and manage glaucoma, Nate Lighthizer, OD, FAAO, said at Vision Expo West.
“We’ve got a lot of different pieces of the puzzle in glaucoma,” Lighthizer faculty member at Oklahoma College of Optometry, said. “We have IOP, OCT, visual fields, but we have no perfect test.”
The Ocular Response Analyzer (Reichert) provides IOPg, which is a Goldmann equivalent, Lighthizer said, and IOPcc, which is corneal compensated IOP.
In addition, it provides a corneal hysteresis measurement, “which is a measure of the shock-absorbing properties of the eye,” he said. “Studies have shown that glaucoma suspects are more likely to convert if they have a low corneal hysteresis, and glaucoma patients are more likely to progress.”
A higher corneal hysteresis measurement of 10 and above is desirable, Lighthizer said. A value of 8 or lower could indicate risk for glaucoma progression.
