Evulsion of the optic nerve: a clinicopathological study.
Four patients with evulsion of the optic nerve caused by blunt trauma were clinically evaluated. The evulsion was complete in two of the patients and incomplete in the other two. The patients' visual acuity ranged from counting fingers to no light perception. In addition, two eyes were histopathologically studied. Several explanations of the exact cause and the extent of the evulsion are advanced within this report.
