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?
