What this study found
Daily lutein and antioxidant supplementation for 9 months did not improve contrast sensitivity in ARM-affected eyes compared with placebo. Baseline contrast sensitivity was similar between groups, and the 9-month change was +0.07 log units in placebo versus -0.02 log units in the active group. The between-group difference was not significant (z = -0.903, P = 0.376). Although placebo showed a small within-group improvement (P = 0.03), the active supplement did not show a meaningful benefit, and no adverse events were reported.
- Study & population

- Intervention
- Participants in the active arm took 1 oral tablet daily with food for 9 months.
- Key limitation
- The active arm was small, with only 13 analyzed participants, and the trial had short follow-up of 9 months.
