Swift, blunt, convex non‐penetrating orbital trauma displaces eye tissues backward. Ocular compression transmits intraorbital hydraulic pressure to the bony orbital pyramid walls. Abrupt ocular decompression occurs by means of a pyramid wall fracturing and allowing orbital tissues to herniate into adjacent sinuses: decompression valve. This mechanism of orbital kinetic energy de‐acceleration has been clinically, 1,2 and experimentally 1 described and classified 23 as a pure blow‐out fracture (Table I).
