Vitamins and Anti-oxidant Supplementation

A population-based study demonstrated weak evidence that supplemental vitamin C intake may perhaps be associated with decreased odds of glaucoma; nevertheless the serum levels of vitamin C were not associated with POAG risk.[62] Also, supplementary consumption of vitamins A and E were not associated with risk of POAG. A recent randomized controlled trial compared placebo with a dietary supplement (composed of essential omega-3 polyunsaturated fatty acids, dietary polyphenolic nutrients, vitamins and minerals, and ginkgo biloba extract).[63] The authors found that oral administration of antioxidants produced an increase in biomarkers of ocular blood flow (measured by ultrasound and laser Doppler modalities) within retinal and retrobulbar vascular beds in patients with OAG after 1 month of treatment.[63] Prospective studies with longer follow-up would be necessary to corroborate if these findings have an impact on the incidence of glaucoma among healthy people or in the progression of the disease among glaucoma patients.
