Abstract

The invention provides a glaucoma drainage implant. The glaucoma drainage implant comprises a hollow cylindrical pipe, wherein a friction increase structure for increasing the frictional resistance isarranged outside a pipe wall of the cylindrical pipe along the length direction. The invention further provides a glaucoma drainage device. According to the glaucoma drainage device and the glaucomadrainage implant thereof provided by the invention, the frictional force between the glaucoma drainage implant and a schlemm tube is increased through the arrangement of the friction increase structure on the outer wall of the cylindrical pipe, so that movement is avoided and the long-term treatment effect is good.

Description

technical field [0001] The present application relates to the technical field of medical equipment, in particular to a glaucoma drainage device and a drainage implant thereof. Background technique [0002] Glaucoma is a group of diseases characterized by optic disc atrophy and depression, visual field defect and vision loss. Pathological increased intraocular pressure and optic nerve insufficiency are the primary risk factors for its onset. The tolerance of optic nerve to pressure damage Sex has also been linked to the onset and progression of glaucoma. Obstacles in any part of the aqueous humor circulation pathway can lead to pathological changes caused by elevated intraocular pressure, but some patients also present with normal intraocular pressure glaucoma. Glaucoma is one of the three major blindness diseases that cause blindness in humans, with an incidence rate of 1% in the general population and 2% after the age of 45. Clinically, glaucoma is divided into three cate...
