Abstract

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.
