Age Related Macular Degeneration Clinical Trial
— TARHFOfficial title:
Rationalization of the Systemic Treatment of Age-related Macular Degeneration With Rheohemapheresis (RHF)
In this research rheohemapheresis will be used for the treatment of patients with high-risk dry form of age-related macular degeneration. Correction of rheologic parameters and activation of retinal functional reserves after the therapy will positively influence functional condition of retina. The newest special electrophysiologic methods will be used to determine retinal changes in time. The investigators will also evaluate some important immunologic factors and complement changes as well as define indication criteria more precisely.
