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
Methodology
Meta-analysis of 8 RCTs of lutein/zeaxanthin supplementation in age-related macular degeneration.
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 and zeaxanthin increased macular pigment optical density in a dose-response manner and modestly improved visual acuity in AMD.
Supplementation increased macular pigment optical density in a dose-dependent manner and improved best-corrected visual acuity and contrast sensitivity in AMD patients.
Outcomes Measured
Lutein and zeaxanthin increased macular pigment optical density in a dose-response manner.
