short term outcome of saffron supplementation in patients with age-related macular degeneration: a double-blind, placebo-controlled, randomized trial

in modern pharmacological medicine, saffron is used for various purposes due to its antioxidant effect. this study evaluated retinal function after treatment with saffron supplementation during a follow-up period of 6 months to provide further insight into the efficacy and safety considerations of this treatment. sixty patients with wet or dry age-related macular degeneration (amd) were randomly assigned to oral saffron 30 mg/d or placebo supplementation for 6 months. optical coherence tomography (oct), electroretinography (erg), fluorescein angiography (fa), and visual acuity (va) testing were recorded at baseline, 3 months, and 6 months after treatment. the main outcome measures were oct, erg amplitude, and implicit time. six months after treatment, no statistically significant decrease in oct resultswas observed between the groups with dry amd (p=0.282). however, there was a statistically significant increase in erg results between thegroups at 3 months (p=0.027). in addition, there was a statistically significant decrease in oct results between groups with wet amd atfollow-up (p=0.05). finally, there was a statistically significant increase in erg findings between the groups with wet amd at 3 months (p=0.01), but these changes decreased after 6 months (p=0.213). in conclusion, daily supplementation with 30 mg of saffron for 6 months may induce a mid-term, significant improvement in retinal function in patients with amd.
