A recently granted patent (Publication Number: US11813299B2) discloses a method for treating axial myopia in humans by administering a therapeutically effective amount of crocetin. The method involves administering crocetin at a dosage ranging from 0.075 to 75 mg/day to effectively treat axial myopia, particularly high myopia. Additionally, the method may include administering other carotenoids or polyphenols, excluding ginkgo leaf extract, to individuals in need of treatment.
Furthermore, the patent claims that administering crocetin can inhibit ocular axial elongation and enhance EGR-1 expression, particularly when administered to children during growth. The method is targeted towards individuals who are near workers or indoor workers, suggesting a potential application for those who spend extended periods focusing on close-up tasks.
