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.
报告了两例因交通事故导致前额受伤两小时后眼眶视神经前脱位并断裂而摘除眼球的病理变化。第一例中,小梁网和施莱姆管破裂,睫状体和平坦部上皮破裂,锯齿缘处巨大视网膜裂孔以及视盘处视网膜撕脱,周边部筛板部分破裂,中央部完全破裂,视神经有纵向撕裂,导致眶内视神经在眼球后22毫米处与其鞘膜完全断裂。这些损伤可能是由于额部外伤略呈斜行,伴有旋转力,随后眼球突然向前移动并脱位所致。第二例中,锯齿缘和平坦部有巨大裂孔,平坦部无色素上皮移位至睫状体上方,筛板后视神经束破裂,眼球后16.5毫米处视神经硬膜破裂。
