Research progress of trabecular meshwork cell oxidative stress in the pathogenesis of glaucoma

Glaucoma is a common irreversible blinding eye disease, pathological elevated intraocular pressure is the main clinical feature. The formation of intraocular pressure, related to aqueous circulation, will be pathologically elevated when the aqueous cycle is abnormal. Trabecular network, which plays a key role in maintaining normal intraocular pressure, is the main component of aqueous outflow channel. Imbalance of oxidative stress manifested as oxidation and antioxidant effects is a direct risk factor for elevated intraocular pressure in glaucoma. When it comes to the trabecular meshwork cells, a series of changes such as deposition and degeneration of extracellular matrix, autophagy and aging will eventually occur, and finally the dysfunction of trabecular meshwork cells and increased aqueous outflow resistance, causing intraocular pressure pathological elevated. In this paper, we reviewed the research progress on the relationship between oxidative stress in trabecular meshwork cells and the pathogenesis of glaucoma, in order to provide evidence for further research and reference for exploring the pathogenesis, prevention and treatment of glaucoma.
