在电镜下观察了兔眼视网膜铁锈症中Müller氏细胞的变化。其变化有:(1)细胞变形,极性特征消失;(2)胞突扩张,填补细胞变性的空隙;(3)胞浆内出现大量线粒体;(4)并见色素颗粒及感光细胞的残片;(5)在视网膜不同层次,Müller氏细胞之间形成排列紊乱的粘着小带。证实Müller氏细胞具有相当活跃的吞噬及修补功能。推测含铁物质的毒性可能通过Müller氏细胞传递,影响视网膜色素上皮细胞及感光细胞。
Under electron microscope, the changes of Müller’s cells in retinal rust of rabbit eyes were observed. The changes are: (1) cell deformation, polar characteristics disappear; (2) expansion of the cell process to fill cell degeneration of the gap; (3) a large number of cytoplasmic mitochondria; (4) and see the pigment particles and photoreceptor cell fragments ; (5) at different levels of the retina, Müller cells formed between the disordered adhesion of the small band. Müller cells confirmed that there are quite active phagocytosis and repair function. It is speculated that the toxicity of iron-containing substances may be transmitted through Müller’s cells, affecting the retinal pigment epithelium and photoreceptor cells.
