What Is the Difference Between Ocular Hypertension and Glaucoma?
have a tube on one end putting water in the balloon and a valve at the other end draining the water from the balloon. If this is kept at a steady pace, the balloon will remained filled and the pressure in the balloon will remain constant. Now, if you partially close the drain valve, the balloon will get bigger because you have more water coming in then you have going out. The water pressure in the balloon will also get higher especially if the balloon cannot expand to accept the increased water coming in. The eye cannot expand and so the pressure in the eye goes up and that would be considered ocular hypertension which can lead to damage to the optic nerve. A normal pressure is generally considered to be less than 20 although there are many other factors that need to be evaluated when the eye is examined. Generally speaking, when the pressure is above 20 and no damage has occurred to the optic nerve we call that ocular hypertension. This ocular hypertension can be acute due to some act
