Elevated levels of homocysteine, a non-protein a-amino acid, may increase exfoliation material formation. Research studies have demonstrated that high intake of vitamin B6, vitamin B12 and folate is associated with lower homocysteine levels.
_ Vision HealthHope for New Tx for Retinal Blindness By articleA report published online in in March 2014 in The FASEB Journal may lead the way toward new treatments or a cure for a common cause of blindness called proliferative retinopathies. Scientists at Harvard Medical Schools have shown that the body's innate immune system does more than help ward off external pathogens. It also helps remove sight-robbing abnormal blood vessels, while leaving healthy cells and tissue intact. This discovery is significant because the retina is part of the central nervous system and its cells cannot be replaced once lost.
