What is an eye measurement that is done on patients that have or are suspicious for having glaucoma?

The measurement is called Corneal Hysteresis. Corneal hysteresis is defined as “the difference between the pressure at which the cornea bends inward during an airjet applanation and the pressure at which it bends out again.

This measurement is important as the standard measurement of eye pressure is by Goldmann applanation. Goldmann applanation assumes all corneas are shaped and act the same when pressure is applied to them.

Through different studies we know this is not true and that the thickness of the cornea can play a part in the actual eye pressure.
