青光眼目前是全世界第二位的致盲眼病 ,其特点为视神经萎缩和视野缺损 ;目前认为其病理基础是视网膜节细胞 (retinalganglioncells ,RGCs)的不断丢失及其轴突数目的不断减少。长期以来 ,一直认为病理性眼压增高是青光眼发病的唯一原因 ,随着对青光眼损害的不断研究 ,目前认为病 Currently, glaucoma is the second leading cause of blindness in the world. It is characterized by atrophy of the optic nerve and visual field defects. Currently, it is thought that its pathological basis is the continuous loss of retinal ganglion cells (RGCs) and the decrease of the number of axons. For a long time, pathological elevated intraocular pressure (IOP) has long been considered as the only cause of glaucoma. With the continuous research on the damage of glaucoma,
