Glaucoma is an eye condition where your optic nerve is damaged by the pressure of the fluid inside your eye. 

This may be because your eye pressure is higher than normal, or because of a weakness to your optic nerve. Your eye needs a certain amount of pressure to keep the eyeball healthy and in the right shape. But if the pressure is too high, it can cause your optic nerve to become damaged at the point where it leaves your eye. This damage is called glaucoma.
