Healthy gut bacteria inhibits invasive blood vessels that destroy vision

Eye doctors are busy capturing digital images of the back of your eyes, measuring eye fluid pressure, testing your vision for acuity (ability to see letters of varying sizes), and instilling medicine by direct needle injection into the eyes to inhibit the formation of new blood vessels that invade the visual center of the eyes (macula).  These new blood vessels form when the retina at the back of the eyes becomes starved of oxygen.

The new blood vessel formation in the blood supply layer (choroid) of the eyes is called neovascularization or angiogenesis.

The injected medicines (Avastin, Lucentis, Eylea) are sight savers.  These drugs work by inhibition of vascular endothelial growth factor (VEGF).  They rapidly cause abnormal blood vessels to recede and the effect lasts for about 30-45 days.  About 85% of patients with this fast progressive form of macular degeneration are spared from progressing into legal blindness (20/200 vision or worse).

However, modern medicine may now have a handle on why some 15% of patients are resistant to treatment.

Lo and behold, way down in the depths of your gut (large and small intestine) are about 4 pounds of bacteria that are comprised of trillions of cells that outnumber the cells in the entire body.

Healthy gut bacteria inhibit inflammation.  Unhealthy gut bacteria generates low-grade inflammation that is characteristic of accelerated ageing.

Fermented foods like pickles, sauerkraut, miso soup, apple pectin, beta glucans (barley), resveratrol and other foods are recommended to restore and maintain healthy gut bacteria.

Unhealthy gut bacteria increase intestinal permeability and allow undigested proteins to enter the blood circulation, sparking allergic and autoimmune reactions.  [EMBO Molecular Medicine Oct 11, 2016]
