Glaucoma Screening in Puchong

What is glaucoma?

Glaucoma refers to a group of eye conditions that can damage the optic nerve — the nerve that carries visual information from the eye to the brain. It's often associated with raised pressure inside the eye, though it can occur at other pressure levels too. Left unmanaged, the optic nerve damage it causes can affect vision, typically starting with peripheral (side) vision before it's noticeable in day-to-day life.

One thing that makes glaucoma worth screening for is that it can develop gradually and without obvious symptoms in its early stages — many people don't notice a change in their vision until the condition has progressed. This is why screening looks for signs of risk before symptoms appear, rather than waiting for a patient to report a problem.

Why glaucoma screening matters

Because early glaucoma often has no noticeable symptoms, a routine screening is one of the few ways to pick up on relevant risk factors or early signs before they affect daily vision. Identifying a potential concern early gives more options for monitoring or management than identifying it later.

Screening is not a guarantee — it cannot prevent glaucoma from developing, and it cannot guarantee that every case will be caught at an early stage. What it does is give you and your optometrist useful information to act on, as part of your overall eye health picture.

Who should consider glaucoma screening?

Glaucoma risk isn't limited to one age group, though it does become more common with age. Screening may be worth considering if any of the following apply to you:

• You are around 40 or older
• You have a family history of glaucoma
• You have not had your eye pressure or optic nerve checked before
• You have other risk factors your optometrist has discussed with you, such as certain existing eye or health conditions
• You simply want a baseline check as part of general eye health, regardless of age

If you're unsure whether screening is relevant for you, our optometrists can advise based on your history during a comprehensive eye examination.

What does glaucoma screening involve?

At EyeDeal, glaucoma screening looks at a few different pieces of information together, rather than relying on a single measurement on its own.

Eye pressure / tonometry

Tonometry measures the pressure inside your eye. Pressure that is higher than typical can be one relevant factor in glaucoma risk, though it is only one part of the overall picture — pressure alone does not confirm or rule out glaucoma.

Optic nerve assessment

The appearance and condition of the optic nerve at the back of the eye is assessed for signs that may be associated with glaucoma-related changes.

Risk assessment

Your optometrist considers your eye pressure, optic nerve appearance, and relevant personal and family history together, rather than treating any single measurement as a standalone diagnosis. This combined view helps determine whether monitoring, further assessment, or no action is appropriate.

How often should you have a glaucoma screening?

There isn't a single interval that applies to everyone. How often screening makes sense depends on your age, personal and family risk factors, and any previous findings — your optometrist can advise on a suitable interval for you personally. As a general starting point, adults from around 40 without other risk factors are often advised to have periodic checks, while those with a family history or other risk factors may be advised to be screened more frequently. This is guidance rather than a fixed rule, and your optometrist's recommendation should take priority over any general guideline.

What happens if something looks concerning?

If a screening finds something that warrants a closer look — such as a higher eye pressure reading or an optic nerve appearance that isn't typical — your optometrist will explain what was found and what it may mean. This might involve monitoring the finding over subsequent visits, further assessment, or a referral for specialist evaluation where appropriate. A single unusual reading does not necessarily mean a diagnosis of glaucoma; it means further information is needed, which is why findings are followed up rather than acted on in isolation.
