case_images: The patient was referred for computed tomography (CT) of the head which revealed a predominantly left-sided cerebral contusion without fracture to the skull with localized traumatic subarachnoid hemorrhage (Figure 1). This result was discussed with the regional neurosurgical center who elected for local admission and observation. Given the report of left eye monocular diplopia, assessment began on the right eye which revealed optic nerve prominence, increased optic nerve sheath diameter (ONSD) consistent with papilledema (Figure 2 and Video S1).
case_images: Right eye posterior structures, note the presence of increased optic nerve sheath diameter (ONSD) of 7mm (normal is up to 5mm) and the prominence of the optic nerve into the retina consistent with papilledema measuring 1.4mm from retina base.

case_images: Given the report of left eye monocular diplopia, assessment began on the right eye which revealed optic nerve prominence, increased optic nerve sheath diameter (ONSD) consistent with papilledema (Figure 2 and Video S1).
case_images: Left eye posterior structures, note the presence of increased optic nerve sheath diameter (ONSD) of 7.8mm (normal is up to 5mm), measuring 1.9mm from retina base. The altered probe position avoids the central mass to allow for accurate assessment.

case_images: Left eye vitreous hemorrhage can now also be appreciated anterior to the prominent optic nerve.

case_images: On the assessment of the left eye, a dense irregular mass not fixed to the retina was also visualized (Figure 4).
