Figure 1

Transbulbar sonography and MRI of the optic nerve sheath. (A) The eye bulb and the optic nerve are displayed by B-mode sonography. The optic nerve sheath diameter was measured 3 and 5 mm behind the papilla (dotted arrow) in an axial plane showing the optic nerve in its longitudinal course. Transverse (B) and sagital (C) T2-weighted TSE sequences were created to schedule coronal and orthogonal HASTE sequences of the optic nerve sheath 3 mm (D) and 5 mm (E) behind the papilla.
