Survey of AREDS2 Formula Intake in Korean Patients with Age-related Macular Degeneration

Purpose: To investigate the use of second AREDS2 formula in patients with intermediate or advanced age-related macular degeneration.Methods: A prospective survey was conducted between December 2019 and July 2020. The questionnaire consisted of 24 questions on demographics, disease perception, and formula intake.Results: The survey included 100 patients (males, 56%; age [>60 years], 89%). We found that 66%, 84%, and 93% of patients had a good understanding of their disease, had stopped smoking, and were aware of the need for antioxidant supplements; 58% of patients were aware of the supplement they were prescribed, and 63.8% (37% of total) were using the AREDS2 formula. Only 8% of patients had knowledge regarding the supplement ingredients, and 91% consumed the supplement daily. Patients with long disease duration used supplements less frequently (p < 0.05). Older patients and those with a low education level had a limited perception of the disease (p < 0.05).Conclusions: In this prospective survey, some patients consumed supplements other than the AREDS2 formula. Further studies are required to determine ways to increase the use of the AREDS2 formula.
