title: [A case of evulsion of the optic nerve].
abstract: We examined a 2-year-old child with optic nerve evulsion after facial contusion. The optic nerve head could not be seen because of overlying preretinal and vitreous hemorrhage. Fluorescein angiography demonstrated no infusion of dye into the central retinal artery in the right eye. The electroretinogram was subnormal, and visual evoked potential revealed poor response with right eye stimulation. Ten days later, the fundus could not be seen due to vitreous opacity, so pars plana vitrectomy was performed 62 days after injury and optic nerve evulsion was recognized. This case revealed the possibility of traumatic optic nerve evulsion, even if only very slight skin injury were found around the orbital and ocular regions.
