对人类慢性青光眼和猴实验性青光眼的组织学研究表明,青光眼时视网膜节细胞及其轴突首先丧失。临床上通过视盘和神经纤维层变化(包括杯/盘比、盘沿面积、神经纤维层缺损和神经纤维层相对厚度等)来评价青光眼视神经损害的程度。然而,尚不清楚视盘特征的改变与视神经纤维数之间的确切关系。作者通 Histological studies of experimental chronic glaucoma and monkeys in humans show that retinal ganglion cells and their axons are first lost in glaucoma. Clinically through the optic disc and nerve fiber layer changes (including cup / disk ratio, plate area, nerve fiber layer defects and nerve fiber layer relative thickness, etc.) to evaluate the degree of glaucomatous optic nerve damage. However, it is not yet clear what the exact relationship between changes in optic disc features and the number of optic nerve fibers is. Author pass
