What is it?
Glaucoma is a group of conditions with progressive damage to the optic nerve, often associated with raised eye pressure. As it may cause no clear symptoms early on, regular eye examinations are important.
The assessment includes eye pressure measurement, corneal thickness, optic nerve examination and a visual field test. The optic nerve and retinal nerve fibre layer can be imaged with optical coherence tomography.
Treatment usually starts with eye drops; laser or surgical options are considered when needed. Glaucoma requires long-term follow-up and its course is not the same for everyone; the plan is set with your doctor based on the measurements and updated at check-ups.
Who is it assessed for?
- Those with a family history of glaucoma
- People over forty who have not had regular eye examinations
- Those with high myopia
- Those using steroid medications for a long time
- Those previously found to have high eye pressure
Step by step
- 1
Measurements
Eye pressure and corneal thickness are measured.
- 2
Optic nerve examination
The optic nerve is examined and imaged.
- 3
Visual field test
Peripheral vision is assessed with a computerised visual field device.
- 4
Treatment plan
If needed, eye drops are started and their use is explained in detail.
- 5
Regular follow-up
Measurements are repeated at intervals and compared with earlier results.
Questions
Does high eye pressure mean I have glaucoma?
Not always. Some people have high pressure without optic nerve damage. Optic nerve and visual field assessment are needed to tell the difference.
What if I forget my drops?
Regular use of drops is important for pressure control. If you find it difficult, discussing it at your check-up helps adjust the plan.
How is the visual field test done?
While looking into a device, you press a button when you see lights appear. The test takes a few minutes per eye.
