Glaucoma,a group of optic nerve degenerative diseases,is characterized by papillary atrophy,visual field defects,and decreased vision.It is also the leading cause of irreversible blindness worldwide,significantly reducing patients'the quality of life of patients and posing considerable health economic burdens.However,the pathogenesis of glaucoma remains unclear,and promoting aqueous humor outflow to reduce intraocular pressure is the only treatment option available to slow disease progression.The main pathway for aqueous humor outflow is through the trabecular meshwork into Schlemm's canal and finally into the episcleral veins,highlighting the crucial role of the trabecular meshwork in regulating aqueous humor outflow and maintaining intraocular pressure balance.In recent years,there have been notable breakthroughs in in vivo and in vitro aqueous humor outflow measurement techniques and trabecular meshwork imaging technologies.Many studies suggest that the trabecular meshwork exhibits pressure-dependent rhythmic pulsation,playing a crucial role in the pulse-like outflow of aqueous humor.Unfortunately,in glaucoma,this pulsation weakens or even disappears as the disease progresses.This article focuses on the trabecular meshwork's pump theory and summarizes the latest research progress in aqueous humor outflow in glaucoma,exploring potential effective therapeutic strategies aimed at restoring trabecular meshwork function.This provides new insights for the clinical diagnosis and treatment of glaucoma.
