Study Shows Pure Vision Method Is Based On Science

Here is an interesting study that shows that the PureVision Method is based on science, not ficiton. Nutrition is a cornerstone for glaucoma patients. Without sufficient amounts of essential nutrients, glaucoma patients will lose their vision.

Vision loss is directly related to anti-oxidants and essential nutrients.

Study Abstract:

Glaucomatous optic neuropathy implies loss of retinal ganglion cells, including their axons,and a major tissue remodeling, especially in the optic nerve head. Although increased intraocularpressure is a major risk factor for glaucomatous optic neuropathy, there is little doubt that other factorssuch as ocular blood flow play a role as well. Mechanisms leading to glaucomatous optic neuropathy are not yet clearly understood. There is, however, increasing evidence that both an activation of glialcells and an oxidative stress in the axons play an important role. Glial cells may be activated by mechanical stress via activation of the epidermal growth-factor-receptor, or by ischemic stress via anincrease in endothelin. Several factors can systemically or locally increase oxidative stress.

In glaucoma,an unstable ocular blood flow leading to repeated mild reperfusion seems to be most relevant ininducing oxidative stress. The simultaneous production of nitric oxide in the astrocytes and of superoxide in the mitochondria of the axons leads to the production of the damaging peroxynitrite.Therapeutically, we need to reduce intraocular pressure, stabilize ocular blood flow, and reduceoxidative stress. Various natural compounds possess potential antioxidative value. Reduction of oxidative stress at the level of mitochondria can be achieved by gingko biloba.

Polyphenoliccompounds, such as tea, red wine, dark chocolate, or coffee have antioxidative properties. Coffeecontains 3-methyl-1,2-cyclopentanedione (MCP), capable of scavenging peroxynitirite. Red wine-polyphenols (e.g., resveratrol), exert vasoprotective effects by inhibiting the synthesis of endothelin-1.Dark chocolate decreases blood pressure and improves endothelium-dependant vasorelaxation. Anthocyanosides (bilberries) owe their antioxidant effects to their particular chemical structure. Otherantioxidants include ubiquinone and melatonin.
