Abstract
Age-related macular degeneration (ARMD) leads to impaired vision and potential blindness. Globally, it accounts for approximately 9% of vision loss cases, and a projected 288 million individuals will be affected by 2040. Current treatments have limitations such as variable effectiveness, high costs, and potential side effects. Additionally, atrophic ARMD management remains challenging. As saffron has shown promising neuroprotective and antioxidant effects by potentially delaying disease progression, this study aims to review the mechanistic, pre-clinical, and clinical evidence of the effects, safety, and tolerability of saffron in ARMD treatment. The Scale for the Assessment of Narrative Review Articles was applied in this narrative review. To find relevant literature, the syntax "(saffron OR crocus) AND (retin* OR "geographic atrophy" OR "choroidal neovascular*" OR "macular degeneration")" was searched in PubMed/MEDLINE. Pre-clinical and clinical original investigations of the effects of saffron in ARMD along with the eligible studies cited in their reference lists were identified and included. Saffron and its active compounds, crocin and crocetin, have shown promising results in improving visual function and delaying ARMD progression. Several clinical studies have found that daily supplementation with 20-50 mg of saffron or 5-15 mg of crocin for 3-12 months significantly improved best-corrected visual acuity, contrast sensitivity, and retinal function as measured by electroretinogram and microperimetry, with benefits observed in both dry and wet forms of ARMD. The effects were independent of genetic risk factors and maintained during the follow-up periods, suggesting the potential role of saffron as a long-term treatment option. Saffron reduces ARMD progression via anti-angiogenic, neuroprotective, and antioxidant mechanisms. Moreover, saffron is safe and well tolerated. Although further research is needed to confirm long-term safety and efficacy, current evidence supports the use of saffron or crocin supplements as a safe and tolerable adjunct therapy for ARMD management.
