多种因素可影响成年哺乳动物视网膜神经节细胞 (简称节细胞 )损伤后的存活和再生能力 ,其中轴突损伤距胞体的距离甚为重要。既往研究发现 ,于颅内切断视神经后 ,节细胞的存活率显著高于眶内视神经切断者 ;将周围神经移植于眶内切断的视神经残端时 ,可见大量节细胞的受损轴突再 A variety of factors can affect the adult mammalian retinal ganglion cells (hereinafter referred to as ganglion cells) after the survival and regeneration of the injury, in which axonal damage away from the cell body is very important. Previous studies have found that in the intracranial cut optic nerve, the survival rate of ganglion cells was significantly higher than orbital optic nerve cut off; the peripheral nerve transplanted into the orbital sever optic nerve stump, we can see a large number of ganglion cells damaged axons
