METHOD FOR SURGICAL MANAGEMENT OF THROMBOSIS OF CENTRAL RETINAL VEIN AND ITS BRANCHES Russian patent published in 2015 - IPC A61F9/08 A61N5/67 A61K38/43 A61P27/02 

FIELD: medicine.

SUBSTANCE: method involves sclera puncture in one of external oblique meridians of an eyeball, epiretinal administration of Gemasa 500 international units as close to an occlusion point as possible and retinal laser coagulation in the postoperative period at power 300-400 mW, exposure time 0.1-0.2 s. Immediately before the enzymatic preparation is introduced, the involved vein is massaged with a hooked end of an injection needle by performing 5-7 motions along the involved vascular stem from a distal to proximal end for 20-30 s. The contact-free retinal laser coagulation follows 2 or 3 days later. Thrombosis of the central retinal vein first requires a macular barrage in the form of a horseshoe open to an optic disk; the coagulates are applied at min. 2550-2600 mcm from a fovea; a spot diameter is 50 mcm in the single flash mode in the number of 20-25 applications; the laser is then taken to an automatic operation; and the other retinal segments are coagulated in the staggered order, thereby increasing a spot diameter up to 80-100 mcm, except for a papillomacular bundle; about 400-450 applications are used in a back pole. Treating retinal vein occlusion is ensured by paravasal laser coagulation; the laser coagulates 80-100 mcm in diameter are applied along the involved branch of the central retinal vein at min. 1600 mcm from each other in the number of 100-140 applications.

EFFECT: method enables producing a stable therapeutic effect.
