"The thickest corneas I have ever seen"

My father had glaucoma for many years.  At my last eye exam, the intraocular pressure was a little high, so I went for a retest today.  Pressure reading is 22 mmHg which is slightly elevated, but the corneal thickness is 680µm.  Since "typical" thickness is only 550µm, this gives a corrected pressure of only 15 mmHg which is within normal range.

Apparently very few folks have corneas that are thicker than 600µm.
