Vision Loss Slowed by Antioxidants

Friday, July 28, 2006

Scientific evidence, as well as common sense, is mounting regarding the need for daily intake of the full-spectrum of micronutrients to protect eye health, in spite of the huge amount of B&L marketing dollars spent advertising the simplistic ARED formulation, which includes questionable amounts of beta-carotene and zinc.

Fish Oil Supplements Safer Than Fish

Friday, July 21, 2006

For optimal health of the whole body, including the eyes, the consumption of two or more servings of fish high in Omega-3 fatty acids per week is advocated by the American Heart Association, the American Medical Association, the FDA and the most recent edition of the peer-reviewed journal, Ophthalmology. However, fresh wat

Zeaxanthin and Diabetic Retinopathy

Friday, June 30, 2006

A large body of literature suggests the retina experiences increased oxidative stress in diabetes. Overproduction of superoxide by the mitochondrial electron transport chain activates nuclear transcription factors (NFkB) and the three major pathways postulated to be involved in the pathogenesis associated with retinal capillary cell apoptosis in diabetic retinopathy.

Beta-Carotene & The Smoker Revisited

Friday, June 23, 2006

An important study published in the American Journal of Epidemiology suggested that smokers who consume a wide variety of dietary antioxidants, including small amounts of natural beta carotene, have a substantially lower risk of developing lung cancer. This was not good news to the vitamin companies who aggressively market beta-carotene free "Smokers" AMD formulations.

Mitochondrial Oxidative Decay and Eye Disease

Friday, June 16, 2006

Mitochondria are the most complex organelles in the cell; they provide energy for all basic metabolic processes including those associated with the retina. They detoxify oxygen, function in calcium and iron homeostasis, and they play a key role in programmed cell death. Oxygen (free radical) damage is produced as an inevitable byproduct of mitochondria function. Mitochondria are particularly vulnerable to this damage as they contain their own DNA.

Nutrients, VEGF, and a Call to Action

Wednesday, June 14, 2006

The vascular endothelial growth factor (VEGF) therapy race has new contenders and this race may eventually prove to be as exciting as the Tour de France, particularly for those affected by the growing epidemic of wet macular degeneration.

The Eye/Brain Connection

Friday, June 09, 2006

Controlling oxidative stress (free radical damage) is a pivotal factor for chronic degenerative diseases of both the eye and the brain. Current science suggests that neurotoxic peptide amyloid-beta (Abeta) can accumulate in the brain and vascular system of those who inherit a specific set of genes.

Eye Health and Glycemic Index

Friday, June 02, 2006

For the past decade epidemiologic studies and clinical trials have been suggesting that diets high in the full-spectrum of vitamins, minerals and antioxidant nutrients lower the risk of degenerative eye diseases. New studies published in the 2006 April and May issues of The American Journal of Clinical Nutrition now suggest an association between consumption of high glycemic carbohydrate foods and both cortical and nuclear lens opacities and macular degeneration.

Women Unaware of Menopause/Dry Eye Connection? Surely They Jest!

Friday, May 26, 2006

The Society for Women's Health Research recent dry eye survey revealed that 62% of menopausal and peri-menopausal women experience dry eye symptoms. The society news release, and all the media coverage headlines, focused on the fact that 84% of the menopausal women surveyed supposedly claimed not to have any idea painful dry eyes could be linked to menopause.

The Digital World and Vision Problems

Friday, May 12, 2006

Studies have found that the majority of people who work at a computer experience dry eye or vision problems. The level of discomfort appears to increase with the amount of computer use. The increased use of recreational gadgets such as Personal Digital Assistants, small laptops, and cell phones used for text messaging and Web access may also be contributing factors to the visual fatigue and discomfort experienced by millions, according to leading expert, Jeffery Anshel, OD.
