What Causes High Pressure Inside the Eye?

High pressure inside of the eye is caused by an imbalance in the production and drainage of the fluid in the front of the eye (aqueous humor). The channels that normally drain the fluid from inside the eye consequently do not function properly or are blocked. Since more fluid is continually being produced within the eye but cannot be drained because of the improperly functioning or blocked drainage channels, the result is an increased amount of fluid inside the eye itself, thus raising the pressure.

Another way to think of high pressure inside the eye is to imagine a water balloon. The more water that is put into the balloon, the higher the pressure inside the balloon. The same situation exists with too much fluid inside the eye, which unlike a balloon, is not distensible. The more fluid, the higher the pressure within the fixed space of the eye. Also, just like a water balloon can burst if too much water is put into it, the optic nerve in the eye can be damaged by pressure that is too high.
