NIJMEGEN, Netherlands — The prevalence rate of age-related macular degeneration is about twice as high in people with low antioxidant and lutein intake as it is in people with higher intakes of those substances, according to investigators here.
Researchers at the university here initiated a case-controlled study with 72 case and 66 control patients in which antioxidant intake, cigarette smoking, sunlight exposure and familial predisposition to age-related macular degeneration (AMD) were all calculated. The prevalence of AMD in people with low lutein and antioxidant intake was about twice as high as in patients with high intake. Further specification of intake data into quartiles of antioxidant intake and lutein intake showed a clear dose-response relationship.
The study is published in the August issue of Acta Ophthalmologica Scandinavica.
