Causes of Pressure in the Eye


Our bodies need fluid in just about every area to keep it working properly. The eyes are no exception. The eyes have fluid in them that is supposed to be at a continual, particular pressure to keep the eyes working at their optimum. But sometimes the pressure can get off-balance and get too low or too high. There are typically physical reasons for any imbalance in pressure, but when pressure gets too high in the eyes, there can be tremendous consequences that can be devastating for the patient.


We need fluid in the eyes for the eyes to function properly. This fluid is called aqueous humor. It constantly circulates to keep the eyes moist and lubricated. It protects the eyes as well as helps them to move properly and keep them from getting too dry or irritated. The eyes are very sensitive organs and require a constant lubrication to keep functioning properly inside and out. The fluid not only helps give the eyes their shape, but it also plays a role in giving them their mobility and ability at sight.


Pressure in the eyes is when the fluid, or aqueous humor, builds to too much, whether from a lack of proper draining or making too much fluid. It can be in one particular area of the eye or throughout the eye. The pressure should stay at a constant level. When the fluid level rises in the eye, the pressure rises in the eye. This pressure is what is dangerous for the eye and its components. The aqueous humor should be able to move about the eyes without building in any particular area to any degree.


There are a few different reasons why someone would get increased pressure in his or her eyes. The biggest reason for pressure on the eyes is glaucoma. Glaucoma is a disease of the eyes in which the pressure in the eyes slowly climbs. This can be due to an overproduction of aqueous humor or because the drainage system does not work properly. When the pressure rises, this can cause pressure on the eye's organs, and eventually there is loss of sight. Diabetes can also lead to glaucoma.

Potential Dangers

When the pressure rises in the eye, it creates problems with the sight of the eye. One organ that is significantly affected in the eye is the optic nerve. Once the optic nerve is damaged due to too much pressure, there is a greater risk for loss of sight.


The first preferable type of treatment for high pressure in the eye is eye drops called prostaglandins. These drops help to shrink areas of the eye that may be inflamed and not allow the aqueous humor to flow properly. Beta-blocker drops may be the next step. If the inflammation does not go down, the beta blockers can help in decreasing the production of the aqueous humor. If neither of the drops works, surgery may be the next step. Most times, because the eye is so intricate and sensitive, surgery for the eye is done under laser surgery.


Prevention of pressure in the eye is pretty quite simple. First, it requires regular visits to the doctor. You should see your optometrist regularly, especially if you have had glaucoma and especially if you have been diagnosed with diabetes. Taking your diabetic medication as directed is also important.
