The Cost-effectiveness of Vitamin Therapy for Age Related Macular Degeneration

This 2007 study simulated the incidence and natural history of age-related macular degeneration (AMD) with and without the use of prophylactic antioxidant vitamin plus zinc supplements to prevent advanced vision threatening disease. The study found that the universal use of vitamin therapy would reduce the percentage of patients with early AMD who ever developed visual impairment in the better-seeing eye to 5.6% compared to 7.0% without such therapy. Compared to no therapy, vitamin therapy cost approximately $21,000 per quality adjusted life (QALY) gained, in 2003 dollars, a cost that was favorable compared to other ocular health interventions.
