Evidence of orbital deformation in indirect optic nerve injury. Weight lifter's optic neuropathy.
A 16-year-old boy developed monocular visual loss due to optic neuropathy following frontal head trauma. His trauma was unique in that it consisted of a static loading force to the brow, rather than the dynamic impact more commonly associated with blunt orbital injuries. This case demonstrates the role of isolated deformation of orbital bones in the pathogenesis of indirect optic nerve injury.
