Age-related macular degeneration (ARMD) is a progressive disease affecting the central vision of patients older than 55 years. Typically, ARMD patients are classified into dry and wet forms based on clinical characteristics. This has important implications with respect to their clinical presentation, prognosis and management options. Important risk factors in the progression of disease include age, smoking and drusen characteristics. The promising results of a new study on vitamin supplementation provide direction for treatment and prevention, as well as the understanding of the role of antioxidants in ARMD pathogenesis. High-dose vitamins (beta- carotene, vitamins C and E and zinc) should be considered in certain patients with ARMD.
