Glaucoma screening is a set of quick eye tests used to look for early signs of glaucoma before noticeable symptoms develop. It is especially important for people with risk factors such as family history, high eye pressure, or older age.
What it involves
Screening does not replace a full eye exam but can highlight who needs detailed assessment.
- Measurement of eye pressure, often with a puff of air or a handheld device
- Simple optic nerve checks with a light or camera
- Basic visual field screening to look for blind spots
- Referral for comprehensive glaucoma testing if anything looks suspicious
Why it matters
Glaucoma damage is usually permanent, so early detection is key.
- Helps pick up disease while vision is still normal or only mildly affected
- Allows timely treatment with drops, laser, or surgery to protect sight
- Recommended at regular intervals for high‑risk groups
- Should always be followed by full specialist review if abnormalities are found
