|概要||Anthocyanin (AC) is widely used as supplement of eye health in Europe and in East Asia.
In this review, I describe AC effects to clarify the mechanism is important in order to understand
the effects of AC on vision health. The bioavailability of AC is quite low but, reported as intact form
and many kinds of metabolite. And AC passes through the blood-aqueous fluid barrier and bloodretinal
barrier. In vitro study, AC had a relaxing effect on ciliary muscle which is important to treat
both myopia and glaucoma. And AC stimulate the regeneration of rhodopsin in frog rod outer
segment. Furthermore, AC could inhibit the axial length and ocular length elongation in a negative
lens-induced chick myopia model. In addition, we summarized clinical studies of AC intake
improved dark adaptation and transient myopic shift and the improvement on retinal blood
circulation in normal tension glaucoma patients.
