Definitions
- the present invention relates to an implant for draining aqueous humor from the anterior chamber into the episcleral veins, for use in glaucoma, consisting of the measures listed in the preamble of claim 1.
- Glaucoma is a disease characterized by chronic progressive optic nerve lesion with the main risk factor of increased intraocular pressure. Approximately 2 ⁇ l aqueous humor is produced inside the eye per minute, which can be seen through the trabecular meshwork in the anterior chamber of the eye and into the Schlemm 'canal, and from there via the aqueous veins into the venous system. The main physiological resistance for this aqueous humor outflow is in the juxta-canalicular part of the trabecular system, i.e. between the anterior chamber and the Schlemm 'see channel. This resistance is pathologically increased in chronic open-angle glaucoma.
- Fistulative glaucoma surgery is currently the standard procedure for the surgical lowering of eye pressure in glaucoma patients.
- the aqueous humor is drained from the anterior chamber under the conjunctiva through a scleral wound. There, the aqueous humor is absorbed by veins and transported away. While short-term success is acceptable at around 90%, wound healing often leads to occlusion of the fistula over a period of a few years and thus to a late failure of the operation.
- Cyclodialysis uses another drainage path for the aqueous humor.
- the sclera is cut about 3 mm from the limbus of the cornea and a spatula is inserted through it between the sclera and the underlying ciliary body.
- This spatula is pushed forward to the chamber angle and thus opens the anterior chamber of the eye.
- This creates a connection between the anterior chamber and the gap between the ciliary body and the sclera (ie the supra-ciliary gap).
- the success rates of this operation are acceptable, the technique has been tied very frequent and difficult to control hypotension.
- the device described in WO 00/13627 AI also aims to improve the outflow of aqueous humor from the anterior chamber into the Schlemm 'see channel, and at the same time to keep the Schlemm' see channel open.
- a stent is implanted in the Schlemm's canal, which stretches the trabecular structure and has openings directed towards the trabecular structure.
- the direct implantation of a drainage implant in the Schlemm's Canal appears to be a useful way. While this could offer the advantage of a physiological drainage path, such a solution is not an option for some patients.
- the Schlemm's canal could be partially obliterated or at least its function impaired (Ritch R, Surv Ophthalmol 2001; 45: 265). In these cases, direct drainage into the episcleral veins could help.
- the implant according to the invention has the features highlighted in the characterizing part of claim 1 Characteristics on.
- FIG. 1 is a schematic representation, the drainage implant partially in accordance with the present invention in the view from above;
- FIG. 2 shows a schematic illustration, which shows a drainage implant partially in accordance with the present invention viewed from the side;
- Figure 3 is a schematic diagram showing a detailed view of the distal end of a drainage implant partially in accordance with the present invention
- Figure 4 is a schematic illustration showing a drainage implant partially in accordance with the present invention after removal of the guidewire.
- Figure 5 is a schematic illustration showing a drainage implant partially in accordance with the present invention in one embodiment with two tubular parts.
- the present invention is directed to an implant for draining aqueous humor from the anterior chamber into the episcleral veins.
- Figures 1-4 show an embodiment of the present invention of the implant with a tubular part 1, which has at least one lumen and can be inserted with its open proximal end 2 to drain the aqueous humor into the anterior chamber of the eye, and with its open distal end 3 in an episcleral vein can be inserted.
- the tube 1 is covered with plastic, this covering in the central area 5 being designed as a plate 6 with eyelets 7 in order to enable stabilization and fixation of the implant by means of sutures.
- the implant inside the tube 1 contains a guide wire 8 sharply pointed at the front, which on the one hand stabilizes the very thin tube 1 and with which the vein is punctured secondly.
- the conjunctiva is opened, an episcleral vein is shown and punctured with the tip of the guide wire 8.
- the distal end 3 of the tube 1 is pushed into the vein and then fixed sclerally at the eyelets 7 with sutures.
- the guide wire 8 is removed and the proximal end 2 of the implant is introduced into the anterior chamber of the eye by a limbal incision of suitable diameter.
- the proximal area 4 and the central area 5 of the implant can be placed under a scleral flap.
- FIG. 5 shows an exemplary embodiment in which the proximal region 4 and the central region 5 of the implant are designed as a double-lumen tube. This branches at the distal end 3 into two separate tubes 1, each of which can be inserted into an episcleral vein.
- the double tube is sheathed with plastic in the proximal area 4 and in the middle area 5, this sheathing being formed in the middle area 5 as a plate 6 with eyelets 7 to enable the implant to be stabilized and fixed by means of sutures.
