Eye Pressure Check

An eye pressure check, clinically known as tonometry, is a vital diagnostic test used to measure the intraocular pressure (IOP) within your eyes. Maintaining the correct balance of fluid pressure is essential for protecting the optic nerve, which transmits visual information to the brain. Because high eye pressure is the primary risk factor for glaucoma—a "silent" condition that can lead to irreversible blindness—regular monitoring is a cornerstone of proactive eye care.

At Eyesight.sg, our eye pressure checkup clinic offers precise assessments using modern technology to ensure your eyes remain healthy and your vision stays clear.

Why Is an Eye Pressure Check Important?

The front part of your eye is filled with a clear fluid called aqueous humor. This fluid is constantly produced and drained to maintain a stable internal pressure. If the drainage system is blocked or the eye produces too much fluid, the pressure rises, potentially damaging the optic nerve.

The Connection to Glaucoma

A professional glaucoma screening in Singapore almost always begins with an IOP measurement. Glaucoma often progresses without any pain or early symptoms. By the time a patient notices "tunnel vision" or sight loss, the damage is already permanent. An eye exam with pressure check is the only way to detect these changes in their earliest, most treatable stages.

Normal vs. High Eye Pressure

While every individual is different, "normal" eye pressure typically ranges between 10 and 21 mmHg.

• Ocular Hypertension: Pressure consistently above 21 mmHg. While not everyone with high pressure will develop glaucoma, they are at a significantly higher risk and require regular monitoring.
• Normal-Tension Glaucoma: Interestingly, some patients develop nerve damage even with "normal" pressure readings. This highlights the importance of a comprehensive eye screening package that looks at both pressure and the physical health of the optic nerve.

Common Methods for an Eye Pressure Test

At our eye examination clinic, we utilise different tonometry methods depending on the patient's comfort and clinical needs.

1. Non-Contact Tonometry (The "Air Puff" Test)

This is the most common screening method. A specialised machine sends a quick, gentle puff of air against your cornea. The machine measures how the cornea flattens in response to the air to calculate your IOP. It is fast, requires no numbing drops, and is ideal for routine eye care pressure checks.

2. Applanation Tonometry (Goldmann Method)

Regarded as the "gold standard" for accuracy, this method involves a small probe that gently touches the surface of the eye. Before the test, numbing eye drops and a yellow dye (fluorescein) are applied so you won't feel any discomfort. This method is often used if the "air puff" test shows an elevated reading.

3. Electronic Indentation Tonometry

A portable, pen-like device (often called a Tono-Pen) is used to lightly tap the cornea. This is highly effective for patients who may have difficulty sitting at a larger machine or those with irregular corneal shapes.

What to Expect During Your Eye Pressure Checkup

An eye pressure check in Singapore is a quick, non-invasive procedure that usually takes less than five minutes.

• Preparation: If you wear contact lenses, you will be asked to remove them before the test.
• The Measurement: You will look into a device (for the air puff) or have your eyes numbed (for applanation). You simply need to remain still and look straight ahead.
• Results: The results are available immediately. Your optometrist will explain what your numbers mean in the context of your overall eye health.

Eye Pressure Test Cost in Singapore

The eye pressure test cost can vary depending on whether you are seeking a standalone check or a comprehensive package.

• Basic Screening: Standalone tonometry or basic vision checks can range from $30 to $80 at many private clinics.
• Comprehensive Eye Screening Packages: These packages, which include eye pressure checks, retinal imaging, and specialist consultations, typically range from $150 to $388. These are highly recommended for individuals over age 40 or those with a family history of glaucoma.

At Eyesight.sg, we believe in transparent pricing and provide various eye screening packages to suit different needs and budgets.

Who Should Get Regular Eye Pressure Checks?

High eye pressure can affect anyone, but you should prioritise a glaucoma screening in Singapore if you fall into any of the following categories:

• Age: Individuals over the age of 40 are at a higher risk for increased IOP.
• Family History: Glaucoma has a strong genetic component.
• High Myopia: Very high nearsightedness (above 6.00) is linked to a higher incidence of glaucoma.
• Medical Conditions: Patients with diabetes, high blood pressure, or those who have used corticosteroid medications for long periods should be checked annually.
• Previous Eye Injury: Trauma to the eye can damage the drainage system, leading to "secondary glaucoma" years later.

Our eye pressure checkup clinic is dedicated to providing high-quality, patient-centred care.

• Advanced Technology: We use calibrated, modern tonometers to ensure the highest accuracy.
• Professional Optometrists: Our team is trained to spot subtle signs of optic nerve changes that often accompany high pressure.
• Holistic Approach: We don't just look at the pressure; we evaluate your corneal thickness (pachymetry), which can influence your pressure readings.

Frequently Asked Questions

Q: Does the "air puff" test hurt?

A: No. While the sudden puff of air might cause a momentary blink reflex, it is entirely painless.

Q: Can I drive after an eye pressure check?

A: Yes. Unlike exams that require pupil dilation, a standard eye pressure check does not blur your vision or make you light-sensitive.

Q: Is high eye pressure the same as glaucoma?

A: No. High eye pressure (ocular hypertension) is a risk factor. Glaucoma is a disease characterised by actual damage to the optic nerve. You can have high pressure without glaucoma, but you need regular checks to ensure the nerve remains healthy.

Q: How often should I have an eye pressure check?

A: For healthy adults, once every two years is standard. If you are in a high-risk group, your optometrist may recommend an annual check.
