Fig. 80. Traumatic evulsion of the optic nerve. A. Extensive intraretinal and subretinal hemorrhage is present in the region around the optic disc. The optic disc tissue is not present and appears to be retrodisplaced below the plane of the retina and choroid. B. No optic nerve tissue can be identified in the scleral canal in this histologic section. Extensive retinal and choroidal detachment with proteinaceous fluid in the subretinal and suprachoroidal space is present. There is extensive hemorrhage in the anterior and posterior chambers.
