Effects of Glaucoma
Chronic (primary open-angle) glaucoma is the commonest type, and dangerously it has no symptoms until eyesight is lost at a later stage. Damage progresses very slowly and destroys vision gradually, starting with the side vision. One eye covers for the other, and the person remains unaware of any problem until a majority of nerve fibres have been destroyed, and a large part of vision has been destroyed. This damage is irreversible by any means and it's is progression is usually relentless. Treatment cannot recover what has been lost. But it can arrest, or at least, slow down the damage process.
