Glaucoma is a serious eye condition that can lead to permanent vision loss if not treated. One of the main challenges with this condition is that it often develops silently, causing it to remain undetected. There are usually no noticeable symptoms in the early stages, and by the time symptoms such as peripheral vision loss become apparent, the damage is often already irreversible.
Regular glaucoma screening plays a crucial role in early detection and timely management. Through comprehensive eye assessments, it is possible to identify early signs of glaucoma before significant vision loss occurs.
At our clinic, we provide thorough glaucoma screening using advanced diagnostic tools, allowing for accurate evaluation and personalised care to help protect your long-term vision.

What Is Glaucoma and Why Does Early Screening Matter? |
|
|
Glaucoma is an eye condition that damages the optic nerve, which is responsible for transmitting visual information from the eye to the brain. This damage is often linked to increased pressure building up within the eye.
The condition can be difficult to detect because vision loss tends to begin at the outer edges of the visual field, rather than the centre. As central vision remains clear in the early stages, everyday activities such as reading or using digital devices are often unaffected. This makes the changes less noticeable, allowing the condition to progress without drawing attention.
Early screening and detection are important as they allow changes in eye pressure and optic nerve health to be identified before vision is significantly affected.

Who Should Consider Glaucoma Screening? |
|
|
Glaucoma screening is recommended for individuals who may have a higher risk of developing the condition, even if there are no noticeable symptoms. You may want to consider screening if you:
- Are over the age of 40, or have a family history of glaucoma
- Have been informed by a doctor that you have high eye pressure, or have suffered from a previous eye injury
- Have chronic medical conditions such as diabetes or hypertension
- Experience frequent changes in vision or require regular updates to your spectacle prescription
If you fall into any of these groups, regular eye assessments can help detect early changes and support timely management.

What Happens During a Glaucoma Screening? |
|
|
A glaucoma screening involves a series of non-invasive tests to assess different aspects of your eye health. These tests are quick, routine and designed to detect early signs of glaucoma before noticeable symptoms develop.
During your screening, you may undergo these tests:
- Visual acuity test: Checks how clearly you can see at different distances, helping to assess overall vision quality
- Tonometry (eye pressure test): Measures the pressure inside your eye, as elevated pressure is a key risk factor for glaucoma
- Optic nerve assessment: The doctor examines the optic nerve for signs of damage or changes associated with glaucoma
- Retinal imaging: Advanced scans capture detailed images of the retina and optic nerve
All tests are generally comfortable and do not involve any surgical procedures. Most can be completed within a single visit, making glaucoma screening a straightforward step in protecting your long-term eye health.

Frequently Asked Questions (FAQs) About Glaucoma Screening |
|
How often should I go for glaucoma screening?
Adults aged 40 and above should undergo glaucoma screening once every 1–2 years. If you have higher risk factors such as a family history of glaucoma, high eye pressure or existing medical conditions like diabetes, screening should be done annually or as advised by your eye specialist.
|
|
Will I need surgery if I have glaucoma?
In most cases, glaucoma is first managed with medicated eye drops, which help reduce eye pressure by either decreasing fluid production or improving drainage.
If eye drops are not sufficient, laser surgical treatments may be used to further improve fluid outflow or control pressure.
More advanced interventions are only considered when these methods are not effective or the condition is progressing. The overall goal of treatment is to lower eye pressure and prevent further damage to the optic nerve, rather than to cure the condition.
|
|
Can children or younger adults get screened?
Yes. While glaucoma is more common in older adults, children and younger individuals can still develop certain types of glaucoma or have risk factors that require monitoring. Screening can be performed at any age if there are concerns about eye health.
|
|
How long does a glaucoma screening session take?
A glaucoma screening typically takes about 30–60 minutes. This includes all necessary tests such as eye pressure measurement, optic nerve assessment and imaging scans.
