METHOD FOR THROMBOSIS TREATMENT IN CENTRAL VEIN OF RETINA AND ITS BRANCHES

摘要

FIELD: medicine, ophthalmology.;SUBSTANCE: under ophthalmoscope a single dose 500 IU of haemase is introduced into the eye epiretinal space, near thrombotic obturation zone of the vein. 14-16 days later, the retina coagulation by argon laser is carried out. Firstly, barrage of macular zone is implemented in horseshoe form, the fugure being opened towards disk of optic nerve. Coagulates are applied at the distance not less than 2500 mcm from the central pit in single flashes mode, rated 300 to 400 mW, exposition time 0.1-0.2 sec, and light beam diameter 50 mcm. Number of applications is 20 to 30. Then the laser is switched to automatic mode and coagulation of the rest retina parts is implemented, excluding the papillo-macular bundle. The same radiation parameters are used, except the light beam diameter is 100 mcm. Up to 500 application are made altogether, distanced to 2000 mcm one from another. In case of thrombosis of retina central vein branch, focal laser coagulation is carried out in the damaged branch quadrant only, by making up to 150 applications.;EFFECT: high and constant therapeutic effect under sparing laser therapy technique; complications diminishing during and after the treatment.;2 ex, 4 dwg, 6 tbl
