What is normal eye tension?
Eye pressure is measured in millimeters of mercury (mm Hg). Normal eye pressure ranges from 10-21 mm Hg. Ocular hypertension is an eye pressure of greater than 21 mm Hg.
What percentage of glaucoma is normal tension?
In the United States, roughly half of all glaucoma patients have normal-tension glaucoma, with eye pressures below 22, according to the Baltimore Eye Study.
What is a high number for eye pressure?
Measuring Eye Pressure Normal eye pressure ranges from 12-22 mm Hg, and eye pressure of greater than 22 mm Hg is considered higher than normal. When the IOP is higher than normal but the person does not show signs of glaucoma, this is referred to as ocular hypertension.
How is eye tension measured?
Your ophthalmologist will instruct you to position your head into a device called the slit lamp. Then, a small tip gently touches the surface of the eye and the eye pressure is measured. The eye pressure is measured based on the force required to gently flatten a fixed area of the cornea.
Can ocular hypertension be cured?
There is no cure for ocular hypertension. However, with careful monitoring and treatment, when necessary, you can decrease the risk of damage to your eyes.
What happens if eye pressure is too high?
High eye pressure significantly increases your risk of damage to the optic nerve, causing glaucoma and permanent vision loss. If you have ocular hypertension, your eye doctor may recommend a visual field test to check for glaucoma-related vision loss.
Will I go blind with normal tension glaucoma?
Conclusions.: The probability of blindness in eyes with NTG is much lower than previously reported in patients with high-tension glaucoma. Nevertheless, special care should be taken to follow NTG patients, and especially those with worse BCVA and more advanced visual field loss at diagnosis.
What is the best treatment for normal tension glaucoma?
Normal tension glaucoma is generally treated the same way as open angle glaucoma— by reducing the IOP to an even lower level than normal. This is usually accomplished through anti-glaucoma eye drops, laser treatments, or surgery.
How can I lower my eye pressure fast?
These tips may help you control high eye pressure or promote eye health.
- Eat a healthy diet. Eating a healthy diet can help you maintain your health, but it won’t prevent glaucoma from worsening.
- Exercise safely.
- Limit your caffeine.
- Sip fluids frequently.
- Sleep with your head elevated.
- Take prescribed medicine.
Can stress raise eye pressure?
Some studies have suggested that psychological stress can increase eye pressure. The relationship is not known, though it may be that certain hormones and chemicals released during times of stress can affect receptors in the eye. It stands to reason, then, that stress reduction may be useful for glaucoma management.
