The Sonographic Assessment of the Optic Nerve Sheath in GCA (SONIC-GCA) study will: 1) assess the performance, in terms of sensitivity and specificity, of the optic nerve sheath diameter (ONSD) to detect new-onset, active GCA; 2) evaluate the intra- and interobserver reliability of ONSD measures; 3) establish if an association exists between the ONSD and the presence of GCA retinal findings; and 4) evaluate if the ONSD is a dynamic biomarker of GCA remission and relapse.
