Why Is Corneal Thickness Relevant?
The corneal thickness is usually measured at the first clinic visit using an ultrasound device. IOP measurements may be read too high if the thickness is above average or too low if the thickness is below average.
Patients with thinner than average thickness corneas (less than 500 microns) may be at increased risk of glaucoma, depending on other risk factors. A thick cornea (greater then 570 microns) may indicate that risk of glaucoma may be low, in the absence of other risk factors.
