Lutein and zeaxanthin supplementation and association with visual function in age-related macular degeneration
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
Supplementation increased macular pigment optical density and improved contrast sensitivity in a dose-dependent way; best-corrected visual acuity gains were small.
Conclusions
Lutein and zeaxanthin improve contrast sensitivity more reliably than acuity.
Limitations
Heterogeneous doses; short trials; industry funding common.
Supplements Studied
Zeaxanthin with lutein improved macular pigment density and contrast sensitivity dose-dependently.
Lutein supplementation improved macular pigment optical density and contrast sensitivity.
Outcomes Measured
Lutein/zeaxanthin improved macular pigment optical density and contrast sensitivity.
