A tonometry test, often called an eye pressure test, measures the pressure inside your eyes, known as intraocular pressure (IOP). Tracking IOP is crucial for diagnosing and managing conditions like ocular hypertension and glaucoma, both of which can damage the optic nerve and affect vision if not detected early.
Why Eye Pressure Testing Matters
- Glaucoma Detection: High eye pressure is a major risk factor for glaucoma, one of the leading causes of irreversible blindness.
- Ongoing Monitoring: Regular testing helps eye specialists check how well glaucoma treatments are working and identify issues early.
- Vision Protection: By spotting pressure changes before symptoms appear, tonometry can help prevent long-term vision loss.
Types of Tonometry Tests
- Applanation Tonometry (Goldmann Standard)
- A small flat-tipped device gently touches the cornea to measure eye pressure.
- Considered the most accurate method.
- Non-Contact Tonometry (Air Puff Test)
- A quick puff of air is directed at the cornea.
- No drops or contact needed, making it fast and comfortable.
- Rebound (Digital) Tonometry
- A light probe with a tiny ball briefly touches the eye.
- Provides a painless and quick reading.
What to Expect During the Test
Preparation:
- Remove contact lenses.
- Inform your doctor about any medications or steroids you use.
- Stay relaxed to ensure accurate results.
Procedure:
- Numbing drops may be used for some methods.
- The device measures how much force or resistance is needed to check IOP.
- Results are displayed in millimeters of mercury (mmHg).
Normal Range:
Eye pressure typically falls between 10–21 mmHg. Values outside this range may indicate risk of glaucoma or other eye conditions.
How Often Should You Get Tested?
- Healthy adults: At least once a year.
- People over 40 or with family history of glaucoma: More frequent checks are recommended.
- Glaucoma patients: As advised by your eye specialist for close monitoring.
Takeaway: Protect Your Eyes with Regular Pressure Checks
Tonometry is quick, painless, and one of the most effective ways to safeguard your vision. Regular eye pressure screenings help detect glaucoma early and keep your eyes healthy for years to come.
At Eyemastr, we believe that prevention is the key to lasting eye health. If you’re due for a check-up or have risk factors like age, family history, or eye conditions don’t wait. Book your comprehensive eye exam today and take control of your vision health.
