| Zeaxanthin Visual Performance Randomized Trial | Results Across the 9 RCTs, lutein-containing supplementation significantly improved MPOD (Hedges' g = -0.589, p p = 0.001). | 1 | Wang WX (2026) | From Supplements to Sight: Quantifying the Impact of Lutein and Carotenoid on Age-Related Macular Degeneration-A Systematic Review and Meta-Analysis of Randomized Controlled Trials. |
| Zeaxanthin Visual Performance Randomized Trial | Contrast sensitivity and serum lutein concentrations also improved significantly. | 1 | Wang WX (2026) | From Supplements to Sight: Quantifying the Impact of Lutein and Carotenoid on Age-Related Macular Degeneration-A Systematic Review and Meta-Analysis of Randomized Controlled Trials. |
| Zeaxanthin Visual Performance Randomized Trial | Conclusion Lutein-based supplementation is associated with measurable structural and functional visual benefits in early-stage AMD. | 1 | Wang WX (2026) | From Supplements to Sight: Quantifying the Impact of Lutein and Carotenoid on Age-Related Macular Degeneration-A Systematic Review and Meta-Analysis of Randomized Controlled Trials. |
| Zeaxanthin Visual Performance Randomized Trial | Purpose To quantify the effects of lutein-containing supplementation on structural and functional visual outcomes in patients with age-related macular degeneration (AMD), with particular focus on disease stage and treatment exposure. | 1 | Wang WX (2026) | From Supplements to Sight: Quantifying the Impact of Lutein and Carotenoid on Age-Related Macular Degeneration-A Systematic Review and Meta-Analysis of Randomized Controlled Trials. |
| Zeaxanthin Visual Performance Randomized Trial | This systematic review aimed to evaluate randomized controlled trial (RCT) evidence on the effects of carotenoids, anthocyanins, polyunsaturated fatty acids, and combined nutraceutical formulations on refractive outcomes, axial length, macular pigment optical density (MPOD), visual function, and symptoms of visual fatigue. | 1 | Martinez-Perez C (2025) | Nutritional Supplementation for Myopia Prevention and Control: A Systematic Review of Randomized Controlled Trials. |
| Zeaxanthin Visual Performance Randomized Trial | Eligible studies were RCTs involving individuals with myopia or at risk of myopia, comparing nutritional supplementation with placebo or active controls. | 1 | Martinez-Perez C (2025) | Nutritional Supplementation for Myopia Prevention and Control: A Systematic Review of Randomized Controlled Trials. |
| Zeaxanthin Visual Performance Randomized Trial | Two reviewers independently screened studies, extracted data, and assessed risk of bias using the Cochrane RoB 2 tool. | 1 | Martinez-Perez C (2025) | Nutritional Supplementation for Myopia Prevention and Control: A Systematic Review of Randomized Controlled Trials. |
| Zeaxanthin Visual Performance Randomized Trial | Background/objectives Nutritional supplementation has been proposed as a potential adjunct strategy in myopia prevention and control through antioxidative, anti-inflammatory, and extracellular matrix-regulating mechanisms. | 1 | Martinez-Perez C (2025) | Nutritional Supplementation for Myopia Prevention and Control: A Systematic Review of Randomized Controlled Trials. |
