The results from a new NEI-sponsored study suggest that low ocular levels of antioxidants lutein and zeaxanthin - carotenoids found in dark green, leafy vegetables such as spinach and kale - could contribute to age-related macular degeneration (AMD). The research team also reports that AMD patients who had begun taking high-dose lutein supplements after initially diagnosed with AMD were able return those levels back to normal (1).
Macular carotenoid levels declined with age, reaching a stable low level after age 60, when AMD incidence begins to rise dramatically (Fig 1). They also found that macular pigment levels in the eyes of AMD patients not consuming high-dose lutein supplements were 32 percent lower than elderly normal eyes (p = 0.001) (Fig 2). Patients who began taking high dose lutein supplements (ranging from 4 - 20 mg) after their initial AMD diagnosis had significantly higher macular pigment levels compared to those who did not (p = 0.038). In fact, macular content of the AMD patients using high-dose supplements was also similar to that of normals.
"These results taken together lead us to believe that low macular levels of lutein and zeaxanthin represent a pathogenic risk factor for the development of AMD," (2,3) said lead investigator Paul Bernstein. "As a safeguard, patients at risk for visual loss from AMD should consider supplementing their diets with at least 4 mg of lutein each day along with other antioxidant nutrients."
