An American study questions the effectiveness of top selling nutritional eye supplements.

Only the AREDS and AREDS2 formulas, composed of antioxidants and zinc, proved effective in slowing down the progression of AMD, and only when the disease was in a moderate-to-advanced stage.

Only four products had doses equivalent to AREDS and AREDS 2, four others had doses that were much too weak, and four added vitamins, minerals and superfluous herbal extracts. In addition, none of them indicated for which types of patients a nutritional supplement could be effective.

An anti-inflammatory could be used as a weapon against AMD.

A high concentration of oxygen, also called oxidative stress, is suspected of aiding in the development of several diseases, particularly eye diseases such as macular degeneration. Researchers from Florida claim that sulindac, a well-known anti-inflammatory, may protect the eyes against AMD-related oxidation.

In patients diagnosed with AMD, the retinal pigment epithelial cells that feed retinal cells are damaged by oxidative stress. The researchers demonstrated that sulindac protects these cells against such damage. This could be used as an inexpensive and relatively non-toxic therapy for AMD.
