Eye pressure refers to the pressure within the eye, which is also known as intraocular pressure (IOP). It is an important measurement of eye health and can indicate the risk for certain eye diseases, such as glaucoma.
Understanding eye pressure, its causes and risks, can help individuals take proactive measures to maintain healthy eyesight.
What is Normal Eye Pressure?
Normal eye pressure typically ranges from 10 to 21 millimeters of mercury (mmHg). However, this range can vary depending on age, race, and individual health factors.
It is important to note that while high eye pressure is a risk factor for glaucoma, it does not necessarily mean that an individual will develop the disease.
What Causes High Eye Pressure?
High eye pressure occurs when there is an imbalance between the production and drainage of fluid in the eye. This fluid, known as aqueous humor, helps to nourish and protect the eye.
When the production of aqueous humor exceeds its drainage, it can build up in the eye and cause increased pressure.
Other factors that can contribute to high eye pressure include:.

What Causes Eye Pressure and How to Manage It
- Age – as individuals get older, the risk for developing high eye pressure increases
- Family history – individuals with a family history of glaucoma are at a higher risk for developing high eye pressure
- Eye injuries or surgeries – trauma to the eye or certain eye procedures can cause high eye pressure
- High blood pressure or diabetes – these conditions can increase the risk for high eye pressure and other eye diseases
- Medications – certain medications, such as corticosteroids, can cause high eye pressure
What are the Risks of High Eye Pressure?
High eye pressure can lead to an increased risk for several eye diseases, including glaucoma, optic nerve damage, and retinal detachment. These conditions can cause vision loss or blindness if left untreated.
How is Eye Pressure Measured?
Eye pressure can be measured with a test called tonometry. This test can be done in several ways, including:.
- Applanation tonometry – a small amount of numbing eye drops are applied to the eye, and a device is used to gently press on the surface of the eye to measure the pressure.
- Pneumatonometry – this method uses a small puff of air to measure eye pressure.
- Goldmann tonometry – this method involves placing a small prism on the eye’s surface and measuring the pressure by analyzing the reflection of light through the prism.
How is High Eye Pressure Treated?
Treatment for high eye pressure depends on the underlying cause and severity of the condition. In some cases, lifestyle changes such as regular exercise, a healthy diet, and reducing stress can help to reduce eye pressure.
Medications may also be prescribed to lower eye pressure. These can include eye drops or oral medications that reduce the production of aqueous humor or increase its drainage.
In more severe cases, surgery may be necessary to improve fluid drainage and lower eye pressure.
Conclusion
Maintaining healthy eye pressure is an important part of overall eye health. High eye pressure can increase the risk for several eye diseases, including glaucoma, optic nerve damage, and retinal detachment.
Understanding the causes and risks of high eye pressure can help individuals take proactive measures to maintain healthy eyesight.
