The front part of our eyes is bathed in a clear fluid called aqueous humor. This fluid is constantly being produced and recycled providing nutrition to microscopic parts or our eye’s anatomy, and there is an intricate balance of fluid production and drainage, which defines our intraocular pressure. It’s easy to think about if you compare the front part of your eye to a kitchen sink. If the faucet is on too high, or the drain is not draining properly, more water is collected and stored. In the case of the eye, this causes pressure to elevate. High eye pressure is typically caused by too much aqueous humor production, or more commonly, a problem with the eye’s drain.
