Bilberry Extract and Our Bilberry Ultra

The anthocyanidins in bilberry decrease vascular permeability.^5,7,13,17 How this works is not quite understood yet, but it seems that bilberry anthocyanidins interact with blood vessel collagen in such a way as to slow down enzymatic attack of the blood vessel wall.¹⁷ This may prevent leakage of capillaries, decreasing ocular pressure and relieving painful edemas. Truly impressive in its vascular benefits, bilberry seems to work much like horsechestnut and ginkgo in its ability to relieve vascular insufficiency, and like grape seed in its affinity for the capillaries. These microcirculatory improvements have wide ranging health benefits, as one might expect: bilberry improves peripheral circulation and eye health at the same time.

People who take bilberry for eye health, or who are learning more about bilberry in this context, should be sure to read about Optim-Eyes High-Potency Vision Support with includes bilberry as an ingredient.

Macular degeneration is the progressive loss of vision due to oxidative stress to the macula - the area of the retina where most images are focused. The macula is the area responsible for focused sight or fine vision, and as such, degeneration in this area first manifests itself in the form of blurred or bent lines (otherwise known to be straight and crisp). It is highly prevalent in persons over the age of 55, with as many as 20,000 new cases diagnosed each year. It can, and does, lead to blindness.

There are two types of macular degeneration - "wet" and "dry". In the wet form (more rare), the macula experiences excessive growth of new blood vessels - it is easily treated with lasers, but must be treated early. In the "dry"" form, by far the most common form, the macula suffers from an accumulation of lipofuscin, a pigment that builds up as a result of damaged retinal pigmented epithelium cells. These build-ups can be seen upon retinal examination and are known as "drusen".
