The existing myopia control intervention methods are not fully effective in preventing the rate of myopia progression in children . However, according to a recent study, 7-methylxanthine (7-MX), a caffeine metabolite authorized to treat children to reduce myopia progression in Denmark in 2009, has shown promising results in reducing myopia progression in children. The study was conducted on 711 children between 7 to 15 years of age for an average of 3.6 years.
Key findings Daily intake of 7-MX (0 – 1200 mg) reduced myopia progression (average 1.34 dioptres (D)) and axial elongation in children. Modeling of refractive error showed children taking 1000 mg of 7-MX daily would develop -1.43 D of myopia compared to -2.27 D in untreated children over six years. The axial length would increase by 0.84 mm in children taking 7-MX daily compared to 1.01 mm in untreated children over six years.…
