Computed tomography based measurement of ONSD and ETD. The ONSD was measured at a distance of 3 mm behind the eyeball, immediately below the sclera in a perpendicular vector with reference to the linear axis of the nerve. The ETD was defined as the maximal transverse diameter of the eyeball measured from one side of the retina to the other. ONSD, optic nerve sheath diameter; ETD, eyeball transverse diameter
