The Nobel Prize was awarded in 1998 to Ferid Murad for his discovery that nitroglycerine works by releasing nitric oxide (NO). This seems particularly appropriate because Alfred Nobel's fortune came from his invention of making dynamite from nitroglycerine. Eye care professionals are now carefully monitoring potentially dangerous visual side effects associated with nitric oxide (NO) stimulating pharmaceutical drugs.

What kind of lighting is best for people with retinal diseases like macular degeneration? Researchers tell us that ultraviolet (UV) and blue light rays may be harmful to people with retinal disease, while marketers tell us that lamps with enhanced UV and will help us to see better and stay healthier.

Floppy Eyelid Syndrome (FES) can lead to tear film abnormalities that eventually result in dry eye pain. Although initially reported to be most common in older overweight men, FES also affects women, different age groups, and non-obese people. FES presents symptoms of nonspecific irritation, foreign body sensation, mucoid discharge, dryness, redness, photosensitivity, and eyelid swelling.

New science suggests that mice are far more capable of properly metabolizing many plant based essential fatty acids (EFAs) than are human beings - particularly humans over the age of 40. Science has not always understood this. Many studies examining fatty acid metabolism have been carried out on rodents.

Just as eyelids, jowls, breasts, belly and chins sag with the aging process, apparently so does ocular surface tissue. The somewhat intimidating term used to describe, yet another, degenerative aging event is called conjunctivochalasis. The Tenon's tissue that tightly adhere the eye's conjunctiva to the sclera in our youth tends to loosen and wrinkle with age. Conjunctival sags and wrinkles interfere with the spread of the lipid layer of the tear film, which decreases tear film break-up time and results in evaporative dry eye.

Full-spectrum supplements, eating clean (meaning almost no junk food) and exercise are the best investment you and your patient can make in both short and long term health. Overworked soils, cold storage, food processing, and cooking strips today's foods of a large amount of their nutritional value. Therefore, nutritional needs have overtaken the amount of micronutrients provided in the very best of daily diets.

A recent study suggests the incidence of dry eye to be higher in the Hispanic population than in previously studied populations not selected for age. Another new study suggests a higher incidence of LASIK related dry eye in the Asian population than in the Caucasian population.

It's a major public disservice for the press to sensationalize questionable vitamin E results from the study published in the March 16th 2005 Journal of the American Medical Association (JAMA) when the study authors repeatedly concede that the unexpected results cannot be confirmed by other trials and could be due to chance.

Traditionally, palm readers set up shop in high-traffic tourist areas to attract vulnerable folks high on vacation energy. Unfortunately, some well-meaning physicians have now been convinced by multi-level marketers to set up questionable antioxidant palm reading devices in their offices.

If you had trouble believing the WW2 story about bilberry jam improving the Royal Air Force pilots night vision, you may also have trouble believing the alternative explanation for how all this jam on toast business got started. The second, possibly urban myth, suggests that the first bilberry story was put out as a bit of disinformation to keep the German powers from finding out about the Allies new invention called radar. Since neither version of the story seems to have dependable published support - the truth may forever remain a mystery.
