    Published in Investigative Ophthalmology & Visual Science

    Methodology

    Meta-analysis of 8 randomised controlled trials of lutein and zeaxanthin supplementation in patients with age-related macular degeneration.

    Key Findings

    Supplementation increased macular pigment optical density in a dose-dependent manner and improved best-corrected visual acuity and contrast sensitivity in AMD patients.

    Conclusions

    Lutein and zeaxanthin improve macular pigment density and some measures of visual function in established AMD.

    Limitations

    Small trials with heterogeneous doses and outcome measures; short follow-up; several industry funded.
