METHOD FOR SURGICAL MANAGEMENT OF CLINICAL OUTCOME OF RETINAL VENOUS THROMBOSIS Russian patent published in 2015 - IPC A61F9/08 A61N5/67 A61K31/10 A61K31/195 A61K33/14 A61K31/00 A61P27/02 

FIELD: medicine.

SUBSTANCE: method involves performing a vitrectomy with removing a posterior hyaloids of a vitreous body, and a laser retinal endocoagulation at wave length 532 nm, emitting power 120-200 mWt, pulse length 0.1-0.2 s, spot diameter 150-200 mcm. A chorioretinal venous anastomosis (CRVA) is induced by exposing the branches of the central vein of the retina to the third-order laser light at wave length 532 nm in a number of 4 coagulated, emitting power 500 mWt, pulse length 1 sec and spot diameter 50 mcm. The vitrectomy is preceded by the intramuscular injections of 12.5% etamylate 4ml and the intravenous administration of 0.5% tranexamic acid 1 g 25-30 minutes before. That is followed by the droplet intravenous administration of an infusion solution containing 0.1% perlinganit 10 ml in 0.9% normal saline 100 ml at an initial rate of 5 mcg/min. The area to be exposed to laser is specified at least in 3 diameters of the disk from the optic disk. The third-order laser applications are applied on the branches of the central vein of the retina in a number from 2 to 4 at wave length 532 nm, emitting power 300-400 mWt, exposure 0.5 s, spot diameter 500 mcm in two points in the proximal and distal direction from the CRVA induction point. Immediately before the CRVA induction, a salt-water infusion flow is increased until the central retinal artery starts pulsating. The surgical management is completed by plugging the vitreal cavity with 20% air-gas mixture SF6.

EFFECT: effective management of the clinical course of the retinal venous thrombosis by considerable reduction of postoperative haemophthalmias.
