作者报告2例视网膜中央动脉阻塞,因发病1个月后合并新生血管性青光眼而剧烈眼痛,3个月后摘除眼球。对其视神经连续切片作光镜和电镜观察发现,均在巩膜筛板部的视网膜中央动脉管腔内形成血栓。例1,左眼视神经连续切片的光镜观察:在巩膜筛板部的视网膜中央动脉管腔内,可见由增殖的内皮细胞、平滑肌细胞和胶原纤维组成的血栓。同时还存在有被以内皮细胞的小管腔,此乃血管的再通。这种血栓和血管再通现象,在视网膜中央动脉从进入视神经部到巩膜筛板部均可见到。但是,从视神经鞘到中枢侧
The authors reported 2 cases of central retinal artery occlusion, severe eye pain due to neovascular glaucoma 1 month after onset, and eyeball removal 3 months later. The optic nerve continuous section for light and electron microscopy showed that all in the scleral part of the retinal central artery lumen thrombosis. Example 1: Optical microscope observation of serial sections of left optic nerve: Thrombi composed of proliferating endothelial cells, smooth muscle cells and collagen fibers were observed in the central retinal artery lumen of the scleral part of the sclera. At the same time, there are small lumens of endothelial cells, which is the reopening of blood vessels. This phenomenon of thrombus and revascularization can be seen in the central retinal artery from the optic nerve to the scleral frit. However, from the optic nerve sheath to the central side
