[Contusion and luxation of the eyeball with rupture of the optic fascicle in fronto-basal trauma (author's transl)].
A report is given of the pathological changes in two eyes which were enucleated because of anterior luxation with rupture of the orbital optic nerve two hours after a traffic accident with frontal head injury. In the first case there was rupture of the trabecular meshwork and Schlemm's canal, the ciliary body and epithelium of the pars plana, a giant retinal tear at the ora serrata and a retinal avulsion at the optic disc, a partial rupture of the peripheral and a complete one of the central lamina cribrosa with a longitudinal tear in the optic nerve which lead to a complete rupture of the orbital optic nerve together with its sheats 22 mm behind the globe. The lesions produced arised probably from a slightly oblique course of the frontal trauma with a suggested additional rotating force followed by a sudden anterior movement of the eye with subsequent luxation. In the second case there was a giant tear at the ora serrata and at the pars plana with dislocation of unpigmented epithelium of the pars plana over the ciliary body, a rupture of the optic fascicle behind the lamina cribrosa, and a rupture of the optic dura mater 16.5 mm behind the globe.
