Abstract

The invention provides a glaucoma drainage implant. The glaucoma drainage implant comprises a hollow cylindrical pipeline, a friction increasing structure for increasing friction resistance and a through groove are formed in the outer portion of the pipe wall of the cylindrical pipeline in the length direction, the through groove is formed in the length direction of the outer portion of the pipe wall of the cylindrical pipeline, the through groove enables the interior of the cylindrical pipeline to communicate with the outside from the side face so as to increase the aqueous humor circulationarea, and the width of the through groove is 20-130 micrometers. The invention further provides a glaucoma drainage device. According to the glaucoma drainage device and the glaucoma drainage implantthereof, the friction increasing structure is arranged on the outer wall of the cylindrical pipeline, so that the friction force between the glaucoma drainage implant and a schlemm pipe is increased,movement is avoided, the long-term treatment effect is good, and the aqueous humor circulation area is large.

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...
