From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.
The trial is looking for people over 50 years who may have giant cell arteritis, an inflammation of blood vessels. It tests whether an eye ultrasound measuring the optic nerve sheath helps diagnose it.
- Age
- Over 50 years
- Sex
- All
- Disease stage
- Suspected giant cell arteritis (GCA), not yet diagnosed before.
- Earlier treatment
- People cannot join if they used corticosteroids above 0.5mg/kg in the last 2 weeks.
Main reasons for not taking part
- Past diagnosis of GCA
- Past polymyalgia rheumatica (PMR) without a first PET scan
- Past retinal disease, demyelinating disease (damage to nerve coating), or high pressure inside the skull
- Corticosteroids above 0.5mg/kg in the last 2 weeks

About the trial
What the trial wants to find out
The purpose of this study is to evaluate whether the measure of the optic nerve sheath is a reliable diagnostic marker for giant cell arteritis
The group in the trial
- Orbital ultrasoundsTreatment being tested
Orbital ultrasounds on patients suspected of GCA at the enrollment (M0) and at 6 months if the suspicion of GCA is confirmed after all the tests realized at the enrollment.
Treatment: orbital ultrasound
