Elevated ICP

Eyes directed forward

Axial image, consider both longitudinal and transverse images

Locate optic nerve, measure diameter of optic nerve sheath 3 mm posterior to the globe

2-3 measurements taken

Upper limit: 4 infants, 4.5 mm children, 5 mm adults

*note bilateral optic nerve sheath dilation in elevated ICP, if unilateral other etiology must be considered (i.e., tumor obstructing fluid dynamics in affected eye)

Infection

- Orbital cellulitis

Animation - Normal

Animation - Abnormal

Attention to tissue behind the globe – appropriate depth and gain necessary to visualize

Diffuse swelling, widened orbital soft tissue, thickened medial rectus muscle, fluids in sub-Tenon’s space deep to the sclera
