摘　　要：视神经具有损伤后不可修复再生的特殊性。在视神经相关疾病中,视网膜神经节细胞坏死、凋亡、轴突丢失,继而导致不可逆性的视觉损伤。过氧化物酶体增殖物激活受体(peroxisome proliferator-activated receptors,PPARs)经相应配体激活后,对外周器官及中枢神经系统急慢性损伤具有潜在的神经保护作用。视神经属间脑白质在外周的延伸,其病理生理过程与中枢神经系统具有相似之处,从而使PPARs在视神经保护中的作用成为眼科领域关注的热点。文章就PPARs在眼科领域对视神经损伤的保护作用及其可能机制的研究进展进行综述。Neuronal death is thought to be irreversible. In optic nerve-related diseases, the death and axonal loss of retinal ganglion cells could lead to irreversible visual impairment. A large number of studies support the hypothesis that the peroxisome proliferator-activated receptors（PPARs）, once activated by particular ligands, could have a potential neuroprotective effect on the peripheral organs and the central nervous system suffering from acute or chronic injury. Optic nerve belongs to the extension of white matter in the central nervous system and shares similar pathophysiological processes with the central nervous system, which makes PPARs a hot spot in the field of optic nerve protection. This paper reviewed the effect of PPARs in optic nerve protection and its possible mechanism.
