Are there any new treatments in natural medicine for retinopathy?

Yes! Damage to the retina commonly caused by high blood pressure and diabetes. There are herbs that can strengthen blood vessels and prevent deterioration and leakage. Consider ginkgo, a vasodilator that helps get more blood to retina; grape seed extract, high in proanthocyanidins which prevent blood leakage; quercitin, which can help lower high blood pressure; pycnogenol from pine bark shows promise2.
None. Naturopathy has nothing new or old to offer patients with retinopathy. You should be seeing a retinal specialist.
