hi ( my english is bad sorry)

 My eye pressure is 21-21 (goldmann tonometry) 

And my CTT =614-610

 My cup disc ratio = 0.46 and 0.49 

but he did term me as a Glaucoma suspect, and he wants to see me in 6 months to make sure things are stable. At that point, if they are, it will be just once a year. No treatment for now. my corneal thick.

 

What is my true IOP. How do I have a risk for glaucoma. Can I see a lifetime ?
