METHOD FOR MINIMALLY INVASIVE CORRECTION OF SUBMACULAR HEMORRHAGES Russian patent published in 2023 - IPC A61B17/00 A61F9/07 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to ophthalmology. The formation of sclerostomy with the installation of ports, subretinal injection of a solution of recombinant prourokinase, tamponade of the vitreal cavity with a gas-air mixture are carried out. When carrying out surgical treatment, 2 ports are used at 10 and 2 o'clock with a caliber of 27G instruments. While maintaining the vitreous body and the inner limiting membrane, without suturing sclerostomy. The injection of the subretinal cannula is carried out at an angle of 60 degrees. The volume of recombinant prourokinase solution 400-500 ME is injected through a 38 G cannula at an angle of 60 degrees in the area above 1-1.2 diameter of the optic nerve head from the highest hemorrhage height, 15-20% of the volume of the vitreal cavity is tamponade with a gas-air mixture of hexafluoroethane C2F6, in this case, in the postoperative period, the patient is given a position upside down for two hours after surgery. Then vertically with a directional gaze 60 degrees below the horizon for 48 hours.

EFFECT: method makes it possible to prevent irreversible loss of central vision and increase visual functions while minimizing the traumatic effect on the photoreceptor layer of the retina and preserve the vitreous body.
