CURRENT APPROACH TO THE TREATMENT FOR RETINA VEINS OCCLUSIONS
- retina veins occlusion, treatment, current methods
- In order to determine the treatment tactics and prognosis of retina veins occlusions the authors suggested to take into consideration its localization, type, initial vision acuity and general factors (age, presence of diabetic retinopathy and non-controlled arterial hypertension). They recommended regular examinations within first 3 months then each 2 months per first year of the observation. Each visit should include biomicroscopy, gonioscopy and optical coherent tomography; fluorescent angiography in order to reveal ischemia zones. The treatment should be started from the correction of system risk factors. Systemic use of anticoagulants, fibrinolytic agents and antiaggregants were ineffective and unjustified because it increased the risk of hemorrhage complications. The alternative procedure in first 4-6 weeks from occlusion manifestation was isoor hypervolemic hemodilution in the absence of complications. The administration of troxerutin or pentoxiphylline had to be effective for the improvement the vision acuity prognosis. Necessary attention should be paid to the instillation therapy for glaucoma and ophtalmohypertension (hypotensive medicamentous treatment was conducted by beta-blockers and carboanhydrase inhibitors). In the presence of cystic macular edema the authors recommended to administer corticosteroids (intravitreal implant with dexamethazon, periocular injections of triamcinoloni acetonidum), carboanhydrase inhibitors, non-specific anti-inflammatory drugs instillations, in some cases - retina laser coagulation. Surgical treatment (cornea paracentesis, radial optical neurotomy) was accompanied by high risk of complications and was not practiced on a large scale.
