METHOD FOR SURGICAL TREATMENT OF ACUTE AND CHRONIC DISORDERS IN OCULAR CIRCULATION (VARIANTS) Russian patent published in 2004 - IPC

FIELD: medicine, ophthalmosurgery.

SUBSTANCE: in the first variant of method's implementation one should form a tunnel to posterior ocular pole in inferior-internal quadrant of patient's eyeball to introduce there an elastic polymeric magnetic implant with axis-symmetrical radial or axis-symmetrical axial sign-variable direct magnetic field at induction ranged 0.4-1.6 mTl to be placed around an optic nerve. Implant has got the shape of a strip with the help of which one should embrace an optic nerve, posterior short ciliary arteries and the part of retrobulbar fiber and fix strip's ends together. On finishing therapy course the implant should be left at the site of its location. In the second variant one should toward form two tunnels to posterior ocular pole in inferior-internal and superior-external quadrants of an eyeball. Each tunnel should be introduced with elastic polymeric magnetic implant with axis-symmetrical radial or axis-symmetrical axial sign-variable direct magnetic field at induction ranged 0.4-1.6 mTl to be placed around an optic nerve. Moreover, tube-shaped implant should be precut along its axis into two parts necessary to embrace, by not locking them, an optic nerve, posterior short ciliary arteries and part of retrobulbar fiber. On finishing therapy course the implant should be left at the site of its location. The method enables to improve and stabilize visual functions, improve retinal hemodynamics and that of an optic nerve's disk due to decreased venous stasis, increase average and diastolic rate of circulation, decrease resistance index in the central retinal artery and short ciliary arteries and, also, widen patient's visual field.

EFFECT: higher efficiency of therapy.
