Brief Summary:
The Sonographic Assessment of the Optic Nerve Sheath in Giant Cell Arteritis (SONIC-GCA) study will evaluate the performance of the optic nerve sheath diameter (ONSD), measured via ultrasound, to diagnose and monitor GCA. SONIC-GCA builds upon our previous pilot studies and will answer the following questions:
1. What is the performance of ONSD to identify patients with new-onset, active GCA?
2. Is ONSD useful for monitoring GCA relapses during follow-up?
3. What is the intra- and interobserver reliability of ONSD measurements?
4. Does ONSD differ between patients with and without GCA-related retinal findings?
Detailed Description:
SONIC-GCA is a prospective cohort and validation study conducted in centers of the Canadian Vasculitis Research Network (CanVasc).
