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.

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.

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.

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.

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.

Thomas L. Friedman's best selling book, The World is Flat, brilliantly speaks to the way technology and circumstances have flattened the 21st century world. The new Dry Eye A Practical Guide to Ocular Surface Disorders and Stem Cell Surgery text book, edited by East Indian Ophthalmologists: Amar, Athiya, and Sunita Agarwal, plus an impressive world-wide host of other dry eye expert co-authors, speaks to the new century ease of Internet uploading or downloading dry eye clinical data communications that help to flatten the world of dry eye science.

Many view mountain climbing as the "ultimate" challenge - another metaphor for life itself. Last Tuesday evening Randall J. Olson, MD, mountain climber, runner, all-round athlete, international lecturer and leader in ophthalmic education, was awarded the fifth "Sir Harold Ridley Distinguished Visiting Professorship for Creativity and Innovation in Ophthalmology," by Jerre Freeman, MD and Barrett Haik, MD of the Department of Ophthalmology at the University of Tennessee, Memphis.
