- How it Works
April 19, 2019
If your ophthalmologist has told you that you have high eye pressure, you could be at risk for developing glaucoma. It’s important to understand the risks of glaucoma and treatment options so that you can prevent serious issues such as permanent vision loss.
Eye pressure is also called intraocular pressure or IOP, and it measures the level of fluid pressure inside your eye. Here’s how it works:
Behind your eye’s pupil, lens, and iris, there is a jelly-like fluid called the vitreous gel. Your eye also contains a liquid called aqueous humor between the cornea (the clear protective layer covering the front of your eye) and the iris (the colored part of your eye surrounding the pupil).
If your eyes are healthy, small amounts of aqueous humor enter the eye as equal amounts drain out. This regular flow of aqueous humor maintains healthy eye pressure.
If you experience high eye pressure without any other symptoms, you have a condition called ocular hypertension. Usually, people with this condition won’t experience any vision loss or other symptoms. However, ocular hypertension can lead to glaucoma, which damages the optic nerve and will lead to blindness if left untreated.
Unfortunately, high intraocular pressure and glaucoma often do not have noticeable warning signs until the disease has led to permanent vision loss. Your ophthalmologist can test for high eye pressure during your next complete eye exam. When this condition is spotted early, your ophthalmologist can prescribe medicated eye drops to slow or prevent glaucoma.
Here are some ways to help prevent glaucoma:
