Intraocular pressure
Measurements at different times can reveal fluctuations. We interpret the reading alongside corneal thickness.
Protecting the optic nerve in the long term
Glaucoma diagnosis and treatment
Glaucoma usually damages the optic nerve gradually. Reliable assessment brings together several tests and changes over time, rather than relying on one pressure reading.
Understanding the procedure
Structure, function and risk factors belong together.
Eye pressure is the most important treatable risk factor for glaucoma. But a high reading does not always mean glaucoma, and glaucoma can occur without high pressure. We therefore assess the optic nerve head, nerve fibre layer and visual field together.
Repeated, comparable measurements are especially valuable. They show whether findings remain stable or structure and function change over time.
- Core measurements
- pressure, optic nerve, visual field
- Imaging
- OCT of nerve fibres
- Additional measurement
- Corneal thickness
- Objective
- Detect and brake damage early
Used where needed
The components of glaucoma testing.
The tests needed depend on the optic nerve, pressure, age, family history and previous findings.
Assessment of the optic nerve
We assess the optic nerve head’s shape, rim and possible cupping, documenting it with photographs where needed.
OCT
High-resolution measurements of the nerve fibre layer and selected optic nerve structures are compared with previous images.
Visual field
Perimetry tests visual function, showing characteristic losses of sensitivity and whether they worsen over time.
Step by step
From suspected disease to reliable follow-up.
We recheck an unusual reading and interpret it in the context of all the findings.
Identifying risk
We consider symptoms, family history, medicines, existing conditions and previous readings.
Basic examination
We assess vision, the front of the eye, pressure, drainage angle and optic nerve as needed.
Measuring structure and function
OCT, pachymetry, photographs and visual field tests add targeted information to the examination.
Planning your target pressure and follow-up checks
If glaucoma is confirmed, we agree on treatment goals, therapy and follow-up intervals for your individual case.
Understanding the results
Change over time is crucial.
Devices compare readings with reference data. This is helpful, but cannot replace medical assessment of the optic nerve, image quality, individual anatomy and changes over time.
Treatment aims to reduce your individual risk of further damage. Options include eye drops, selective laser trabeculoplasty and, depending on the type of glaucoma, surgery.
Well prepared
How to prepare for your visit
- Glaucoma drops as prescribed
- Bring current list of medications
- Bring previous OCT, visual field or eye pressure results
- Remove contact lenses before pressure or corneal measurements as instructed
Frequently asked questions
Clear, concise answers.
Is measuring eye pressure enough for an eye health check?
No. Glaucoma assessment also requires specialist examination of the optic nerve. OCT, visual field testing, pachymetry and other tests are added as needed.
Why is visual field testing repeated?
Readings may vary with concentration, tiredness and familiarity with the test. Repeat tests show whether a defect is reproducible and changing.
Can a glaucoma be cured?
Existing optic nerve damage is usually permanent. Timely pressure reduction and regular checks can often slow or stop further progression.
