How does glaucoma progress?

Answer 1

There are many different types of Glaucoma, but I don't have time to tell you all of them, do I?

I'll tell you the two most common types though.

Two types of Glaucoma is "open angle" and "closed angle". Closed angle is when Glaucoma comes suddenly and painfully. Vision loss comes quickly and but the pain quickly leads those infected with it to medical help before the permanent damage is done. Open angle lets the glaucoma disease progress slowly and unpainfully. The person infected usually doesn't know they have vision loss until damage is permanent.

Answer 2

If untreated can lead to optic nerve damage resulting in progressive, permanent vision loss, starting with unnoticeable blind spots at the edges of the field of vision, progressing to tunnel vision, and then to blindness.
