An increase in pressure within your eye can lead to damage to the optic nerve at the back of your eye. When this occurs it is called glaucoma. Glaucoma can lead to a loss of vision if it is not treated. Treatment with acetazolamide helps to reduce eye pressure, and this helps to prevent further eye damage. You will also be given other medicines to help reduce the pressure in your eyes, commonly as eye drops.
