Drainage device special for glaucoma ciliarotomy

Abstract

The invention discloses a flat strip-shaped drainage device which is applied to the operation implantation at the pars plana of a ciliary body to treat the refractory glaucoma. Aqueous humor in an eye is led out of the eye and oozed to the lower part of a conjunctiva through aqueous humor drainage ports and aqueous humor drainage grooves, the aqueous humor drainage volume which is needed in the treatment of the refractory glaucoma can be satisfied, the vitreous-body incarceration at an incision and the incision scar are avoided, and the anterior chamber complication is reduced. The special drainage device is processed by adopting material silica gel or absorptive biomaterial, and is provided with two aqueous humor drainage ports, two or three aqueous humor drainage grooves, and two suture holes. One end of the drainage device is an intraocular implanting end which is 3mm from the suture holes; a head takes the shape of a smooth oval flat strip; the aqueous humor drainage ports are respectively arranged in the two corresponding drainage grooves; when in operation, the implanting end is implanted in the eye and is fixed through suture; the other end of the drainage device is an extraocular drainage end which is relatively long and 10mm from the suture holes, and is provided with two or three drainage grooves.

Description

Technical field [0001] The special drainage device for the pars plana of the glaucoma of the present invention is an aqueous humor drainage device surgically implanted in the pars plana of the human eyeball, and is suitable for treating refractory glaucoma. Background technique [0002] Refractory glaucoma refers to glaucoma that is difficult to respond to conventional drugs and conventional surgery. [0003] At present, the aqueous humor drainage device used clinically for the treatment of refractory glaucoma is only suitable for implantation in the anterior chamber of the human eyeball. The aqueous humor drainage device is composed of a drainage tube and a liquid collector. The aqueous humor is discharged to the liquid collector through the drainage tube, and then seeps into the subconjunctiva of the eye to reduce intraocular pressure and treat glaucoma. However, clinically, many patients often lose the drainage function due to the blockage of the drainage tube or the fi...

AI Technical Summary

Problems solved by technology

However, clinically, many patients often lose the drainage function due to the blockage of the drainage tube or the fiber wrapping of the fluid collector after operation, the intraocular pressure increases, and the glaucoma recurs.

On the other hand, the aqueous humor drainage device implanted in the anterior chamber is limited in the diameter of the drainage tube due to postoperative complications, and it is difficult to obtain the drainage volume required for the treatment of refractory glaucoma, so the clinical application effect is not satisfactory. Aqueous humor drainage devices are complex in structure, expensive and difficult to popularize
