Figure 1

Magnetic resonance imaging scan of the retrobulbar optic nerve ((A) transversal section, and (B) oblique sagittal section) T2WI-FRFSE of the retrobulbar optic nerve (digital field of view = 8, window width = 2,000, window level = 1,000). These images were used to plan the position of three slices at 3, 9, and 15 mm behind the globe of T2WI-FRFSE fat-suppressed sequences to measure the optic nerve diameter, optic nerve sheath diameter, and width of the orbital subarachnoid space at 3, 9, and 15 mm behind the globe.
