The effects of oxygen-ozone therapy on 20 patients affected by age-related degenerative maculopathy have been studied. Visual acuity and eye fluorangiography were the parameters used in order to evaluate the efficacy of the therapy. Medical ozone was administered intravenously according to the technique called "ozonized major autohemoinfusion", the total amount of ozone ranging from 1,500 to 2,000 micrograms per session for a 4 months period. The results have indicated that the majority of patients showed an improvement of their ocular condition, suggesting continuation of this type of investigation on a larger group of people.
