Optic nerve avulsion (ONA) is a rare condition with high morbidity that is characterized by mechanic disinsertion of optic nerve from ocular globe, with total or partial nerve fibers lesion (Foster et al. 1997), mainly associated with high-energy blunt ocular trauma. ONA is reported in automotive accidents, falls, and sport traumas (Chaudhry et al. 2006).
