Abstract

Usage: in medicine, namely in ophthalmology. Essence: in the cavity of the eye as a chemical component using a solution of PVP with mol. weighing 350,000 daltons. Advantageous effect: the method allows to achieve a steady increase in ophthalmotonus.

Description

The invention relates to medicine, namely to ophthalmology.

The purpose of the invention is a persistent increase in ophthalmotonus.

The goal is achieved by increasing the osmotic pressure of the vitreous by introducing polyvinylpyrrolidone into the vitreous with mol. weighing 350,000 daltons.

Example. Patient F., 38 years old, husband, medical history Mg 798, was admitted to KKOKB 01/30/89.

Diagnosis: stage II subatrophy, rapidly progressing, corneal scar, atrophy of the iris of afaka. mooring, coarse destruction of the vitreous body, subtotal detachment of the retina of the left eye.

From the anamnesis: December 1, 1988, penetrating wound of the cornea, intraocular metallic foreign body of the left eye. On December 2, 1988, in the traumatology department, an IMHO of the wound was performed, the intraocular magnetic was removed

foreign body, extraction of traumatic cataract. He was in the department on January 2, 1989, where local and general anti-inflammatory, desensitizing therapy was carried out. At discharge, the vision of the right eye is 1.0, the left eye is pr.certa. Ophthalmotonus of the right eye 25 mm Hg, left eye - 20 mm Hg Examination data at the time of admission 01/30/89: right eye -1.0

left eye 12 mmHg 1.02.89 g operation: the introduction of PVP into the vitreous body of the left eye. The operation was carried out as follows: treatment of the surgical floor according to Bakkal, retrobulbar anesthesia and akinesi 2%

novocaine solution. Breeding eyelids of the operated eye with blepharostat. A stitch-seam is applied to the superior rectus muscle to provide immobilization of the ocular block. A conjunctiva is incised 4-5 mm from the limbus, the sclera is exposed. At the incision site of the conjunctiva, deathermocoagulation of the sclera was performed, after which a U-shaped suture was made in this area, in the lumen of which the sclera was punctured with a Tsur-Nadden needle towards the center of the vitreous body, through which the prepared sterile solution of P0P 33% was slowly pumped . Injected 0.8 ml of the solution until a steady tonus of the eye appears in the range of 20-25 mm Hg. After the introduction of the polymer, the needle was removed and the U-shaped suture was tightened. Conjunctival suture. The operation ended with the parabulbar administration of ristomycin 20,000 units and the application of a monocular ointment dressing. The HDL solution was prepared before surgery. The sterilized PVP solution was stored in the syringe until it was used. In the postoperative period, the patient received local anti-inflammatory therapy, parabulbar injections. The postoperative period was uneventful.

Survey data on the 6th day after surgery:

right eye - 1.0

left eye - 22.1 mm

right eye - 25 mm Hg

Survey data 14 months after administration of the PVP solution into the vitreous body remained stable.

The method enables a metered stable increase in the volume of the subatrophic eye and a persistent increase in ophthalmotonus.
