A prospective, multicenter Canadian diagnostic and longitudinal cohort study evaluating optic nerve sheath diameter (ONSD) measured by ultrasound as a novel tool for the diagnosis and monitoring of giant cell arteritis (GCA). The study integrates standardized imaging, clinical assessment, and biomarker data over 24 months to determine diagnostic accuracy and responsiveness to treatment.
