Assessment of Biomechanics of Orbital Fracture: A Study in Goats and Implications for Oculoplastic Surgery in Humans

Impact energy applied to the orbit through the eyeball is absorbed and dissipated by three primary mechanisms: (1) globe deformation, (2) globe displacement, and (3) orbital fracture. Excess energy (above the energy required for deformation and displacement) ≥2350 mJ will result in an orbital fracture.
