    Lutein and zeaxanthin supplementation and association with visual function in age-related macular degeneration: a meta-analysis

    Liu R, Wang T, Zhang B

    Published in Investigative Ophthalmology & Visual Science

    Key Findings

    Lutein and zeaxanthin supplementation increased macular pigment optical density in a dose-response manner and modestly improved best-corrected visual acuity in AMD.

    Conclusions

    Consistent macular pigment effect, modest visual gain.

    Limitations

    Heterogeneous doses and durations.

    Supplements Studied

    Lutein
    Compound

    Lutein and zeaxanthin increased macular pigment optical density in a dose-response manner and modestly improved visual acuity in AMD.

    Zeaxanthin
    Compound

    Zeaxanthin with lutein improved macular pigment density and contrast sensitivity dose-dependently.

    Outcomes Measured

    Lutein and zeaxanthin increased macular pigment optical density in a dose-response manner.
