Abstract

Drainage for the treatment of glaucoma containing a film of hydrophilic material, characterized in that it is made in the form of a corrugated film with the possibility of reciprocating movement along its central axis of symmetry.

Description

Drainage for the treatment of glaucoma.

The utility model relates to. areas of medicine.

Known drainage containing a plating membrane made of hydrophilic material described in (KrupinT., Kenjiron P. ct aL Filering valve implant snrgeru for eyes with neovascular glaucoma. Amer.Z-Ophtham, 1983, v 99, N 6, P. 338-343.).

However, this drainage has a significant drawback: it is not sufficiently effective.

The technical task is to increase efficiency.

The specified technical problem is solved in that in the drainage for the treatment of glaucoma, containing p-enquis hydrogel material, characterized in that: the drainage is performed in

in the form of corrugated shshmkk. . -- .with an opportunity

. its reciprocating motion is along the central axis

symmetry. / -. . .

The drainage is illustrated by the drawing of FIG. 1,2.

Drainage consists of a hydrophilic material. 1 4 (drainage. Made in the form of a corrugated film I (Fig. 1,2),

made with the possibility of reciprocating motion along the main axis of symmetry.

 Work with. drain; "it is made. as follows. The method is as follows. 11. Initially, the conjunctival flap is cut out and thrown back onto the cornea. Next, make a cut 1/3 thick s.leg

-rys in the form of an isosceles triangle with the base to the limb / Scleralnx flap detached "recline on the cornea. Deep sclerectomy is performed in the form of an isosceles triangle with the base to the limb, opening the anterior chamber and producing an iridectomy. The proposed drainage with the inner end is implanted in the anterior chamber, covered. the ciliary body, and the outer end is removed to the episclera. The superficial scleral flap is returned to its place, covering the drainage, and its apex with the outer end of the drainage is fixed with a nodal suture. Ife. the lateral sides of the scleral triangle impose one conjunctival-scleral suture one at a time, -on the continuous conjunctiva, a continuous suture. Example No. 1. Patient F., born in 1939 , sent to MNTK about an acute attack of post-traumatic glaucoma s / y unstabilized, repeatedly operated.

Medical history. In 1993, a shrapnel wounded his left eye. He went to the doctor, an operation was performed to remove the lens and hanging shells. After 5 months, glaucoma was first detected. From 1993 to 1996, the patient was operated on b or 7 times for glaucoma, of which the last two operations were using drainages made of Teflon and silicone. In both cases, recurrence of IOP elevation was observed after 3 months after surgery. In September 1996, a deep sclerectomy with implantation of the proposed drainage was performed at MBTK MG. From September 1996 to September 1998 the patient did not have a single increase in IOP over 25 mm Hg; Art.

-Example N 2. Patient S., born in 1944, sent to the MNTK MG for secondary neovascular glaucoma (Sturge-Weber syndrome) of the right eye. The diagnosis of secondary glaucoma was

- 2 delivered in 1995, the patient was operated 3 times in the leading institute in Moscow. The interval between the last two operations was 3 months. After the last operation, the recurrence of IOP elevation was felt after 2 months despite the instillation of beta-blockers .; In November 1996, the patient underwent a deep sclerectomy with 1 implantation of the proposed drainage. The operations and the postoperative period were uneventful, from November 1996 to October 1998 the patient did not have a single increase in intraocular pressure. despite the absence of instillations of antihypertensive drugs.

Thus, the conduct of antiglaucomatous surgery with implantation of the proposed insert, allowed to normalize intraocular pressure in both cases, when other methods

were not effective. ..
