Effects of Xanthophylls on Optical Density

Alteration of Optical Density and Plasma Xanthophylls After Short Term Supplementation With Macular Carotenoids in Patients With AMD

The objective of the study was to investigate the influence of a intervention with lutein und zeaxanthin from crucifers on the optical density of the macular pigment of patients with non exudative age-related maculopathy. It is hypothesized that the applied study beverage elevates plasma concentrations of the administered xanthophylls and the optical density after 4 weeks of intervention.

Inclusion Criteria:

• patients with non exudative age-related maculopathy

Exclusion Criteria:

• intake of dietary supplements containing lutein and zeaxanthin
