Problems solved by technology

It embeds the drainage disc under the conjunctiva by making a conjunctival flap, which can easily cause fibrous tissue hyperplasia around the drainage disc, scarring around the drainage disc, and the formation of wrapping bubbles, resulting in the inability of the aqueous humor to diffuse, resulting in an increase in intraocular pressure again, causing surgery. fail

Embodiment Construction

[0023] Combine now figure 1 , figure 2 To further illustrate the present invention, a glaucoma aqueous humor drainage device includes a device body, the device body includes a pressure valve 1, and the pressure valve 1 is connected with an air channel for draining the anterior chamber water into the pressure valve 1. The internal drainage catheter 2 and the pressure valve 1 in the cavity drain the anterior chamber fluid in the cavity of the pressure valve 1 to the external drainage catheter 3 on the ocular surface after reaching the threshold. The inner diameter of the inner drainage catheter 2 is 1mm, and the length is 8mm.

[0024] The pressure valve is a flat structure, which fits the temporal sclera through the curvature of the surface to avoid discomfort, and controls the opening and closing of the valve through the change of the pressure in the cavity.

[0025] The pressure threshold of the pressure valve 1 is 12mmHg. When the intraocular pressure exceeds 12mmHg, the...

Abstract

A glaucoma aqueous humor drainage device and a glaucoma aqueous humor drainage method, the switch of the valve is controlled by the change of the cavity pressure in the pressure valve, when the intraocular pressure exceeds 12mmHg, the valve is opened, and the valve is connected with drainage The tube drains the aqueous humor to the ocular surface, and relieves the patient's discomfort and dry eyes. It can effectively drain the aqueous humor and avoid scarring caused by the conjunctival flap embedding device and the generation of filtering blebs that lead to increased intraocular pressure and cause surgical failure. .

Description

technical field [0001] The invention specifically relates to the technical field of ophthalmology, in particular to a glaucoma aqueous humor drainage device and a glaucoma aqueous humor drainage method. Background technique [0002] Glaucoma, the second leading cause of blindness in the world, is a group of optic neuropathy diseases characterized by structural changes in the optic nerve head, causing visual field defects and ultimately blindness. By 2020, approximately 79.6 million people worldwide will suffer from glaucoma, and more than 11 million people will suffer from glaucoma in both eyes. Lowering eye pressure is the only method proven to be scientifically effective in slowing the progression of glaucoma. Lowering eye pressure in glaucoma patients can be achieved with medication, lasers, and surgery. Anti-glaucoma surgery commonly used clinically at present: trabeculectomy, simple cataract surgery, cataract combined surgery, cyclophotocoagulation. Trabeculectomy is...
