Clinical appearance of our patient. Top row: at presentation, our patient had obvious difficulties to hold his right eyelid open in primary position due to ecchymosis, and there is a moderate limitation of upgaze. Middle row: one week after the trauma, there is still some limitation of upgaze, but the ecchymosis has resorbed enough so that he can hold the eyelid open. Bottom row: Three months after the injury, we did not observe any functional anomaly in primary or upward movement.

CT with 2.5 mm slice thickness showed a minimally displaced fracture of the ethmoid bone without haemorrhage, enophthalmos, and a gross accumulation of air in the right eyelid followed by pressure exertion over the right globe (Fig. 2, 3).
