PURPOSE: The objective of this study was to investigate the optic nerve's elastic properties and optic nerve sheath diameter (ONSD) using shear-wave elastography (SWE) in patients with idiopathic intracranial hypertension (IIH) compared to healthy individuals.
METHODS: The study included 22 IIH patients and 15 healthy subjects. SWEs were performed on the optic nerve and ONSD, and optic nerve stiffness were measured.
RESULTS: The patients with IIH demonstrated higher stiffness of the optic nerve compared with that of healthy volunteers (P < 0.001). The optic nerve sheath diameter of the optic nerve in the IIH group was significantly larger than that in the control group (P < 0.001). There was no correlation between the disease duration and SWE values in the Spearman correlation test.
CONCLUSION: These findings suggest that ONSD can be used as a follow-up method in the treatment of IIH. However, there was not any correlation between the disease duration and SWE-based stiffness measurement of the optic nerve.
