Soluble schlemm pipe sounding and flushing supportTechnical Field
The invention particularly relates to the technical field of glaucoma treatment apparatuses, in particular to a soluble schlemm pipe sounding and flushing bracket.
Background
Glaucoma is the first irreversible blinding eye disease worldwide, and is a major public health problem in China. Current treatment of glaucoma is focused mainly on lowering intraocular pressure (intraocular pressure, IOP) to protect the optic nerve. Dynamic balance of aqueous humor production and outflow plays a key role in IOP regulation. Trabecular meshwork and schlemm tubes are the primary resistance sites to aqueous outflow, glaucoma patients present with abnormal accumulation of trabecular meshwork extracellular matrix and metabolites and collapse of schlemm tubes. Restoring or reestablishing physiological aqueous humor drainage is the direction of future treatment of glaucoma.
