Glaucoma: testing and monitoring

Glaucoma damages the optic nerve, usually without symptoms until vision has been affected. Detection depends on testing rather than how your sight feels.

How we assess it

  • Eye pressure measurement.
  • Visual field testing.
  • Advanced retinal imaging of the optic nerve to track subtle change over time.

What happens next

Where findings suggest glaucoma or a risk of it, we refer into the hospital eye service and continue to monitor alongside your ongoing care.

Common questions

Can glaucoma be detected before symptoms appear?

Usually yes. Detailed optic nerve imaging, eye-pressure measurement and visual field testing pick up changes before you would notice them.

Can normal eye pressure still mean glaucoma?

Yes. Glaucoma can occur even when a pressure reading is within the usual range, so the optic nerve, visual field and change over time are assessed together.

Is sight lost to glaucoma recoverable?

No. Sight already lost cannot be restored, but early diagnosis and consistent treatment can often slow or prevent further damage.

What should I do about sudden severe eye pain?

Severe eye pain, a red eye, blurred vision, rainbow haloes, headache, nausea or vomiting can indicate acute angle-closure glaucoma. Seek emergency medical help immediately.

Who is most at risk of glaucoma?

Risk rises with age and is higher with a close family history, certain ethnic backgrounds, very short or long sight, diabetes, previous eye injury and some steroid treatments.
