What is ocular hypertension? It is the condition that arises when the pressure around or inside your eyes, known as the intraocular pressure or IOP, is above normal levels. This is a serious issue, because when not treated abnormally high pressure of the eye could lead to glaucoma and possibly even long term loss of sight in severe cases. However, this is not always the case.
Ocular hypertension (OHT) happens when the drainage of fluid in and around the eye or aqueous humor is inadequate. The Ocular Hypertension Treatment Study estimates that between 4% and 9% of Americans above the age of 40 suffer from this condition. Unfortunately, you probably wont notice if you have ocular hypertension without seeing a medical professional. This is because the only noticeable symptom is red eyes.
The many factors that can lead to or are believed to correlate with ocular hypertension tend to be identical, or close to identical, to the factors which lead to glaucoma. These factors include over-production of the aqueous.
The aqueous humor (often referred to as the aqueous) is a colorless liquid produced by something called the ciliary body in the eye. This is a gland which is found at the back of the iris. The liquid moves through the eye and fluids the space in between the cornea and the iris, known as the anterior chamber.
The eye contains something known as the trabecular meshwork. This is reasonable for draining the eye of the aqueous. It is located in between the cornea and the iris, and when it doesn’t drain the fluid effectively, it causes hypertension of the eye.
Ocular hypertension is a difficult condition to test, as it has no noticeable signs or symptoms. If you want to check if you have it, ask your doctor of optometry to check the pressure in your eyes with an instrument called a tonometer.
Unfortunately, some medications can lead to ocular hypertension, such as steroid medicines that you may use to for asthma among a host of other disorders. Popular steroidal drops that are often prescribed following eye surgery can result in this problem.
Cannabidiol (CBD) eye drops are a new and innovative way to deal with ocular hypertension. While research into the effects of CBD on the eye in both the short and long-terms, it looks as though CBD drops could play a role in the treatment of ocular hypertension in years to come.
