Researchers in Italy have released a study indicating that nutritional supplements of bilberry and French maritime pine bark can help reduce intra-ocular pressure (IOP). While several factors contribute to the development of glaucoma, elevated IOP is one of the greatest risks. An improved ocular blood flow may help prevent glaucoma.
Authors of the study from the University of Chieti-Pescara in Italy studied thirty-eight subjects with intraocular hypertension. Twenty subjects were given bilberry and French maritime pine bark; eighteen subjects were not treated. The visual acuity, IOP, and ocular blood flow were measured at two, three, and six months. After two months, the group taking the supplements showed a decrease in the mean IOP. No side effects were observed and ocular blood flow improved.
Having reviewed the results, these researchers believe that food supplements of bilberry and pine bark may represent a safe preventative intervention for lowering the risk of developing glaucoma by supporting a healthier pressure in the eyes.
