The objective of Stuart Richer, OD, PhD's original Lutein Antioxidant Supplementation Trial (LAST) was to determine whether specific dietary interventions increased macular pigment optical density (MPOD) and visual function in patients with atrophic age-related macular degeneration (ARMD). His objective with the recent LAST II study was to discern which of the specific characteristics that increase MPOD differentiate a supplement responder from a nonresponder.

Today’s column addresses questions from our recent ASCRS Eyes on Fire lecture. Proteomic science is changing the way many gerontologists think about inflammation, the aging process and degenerative diseases. The term proteomics was coined as an analogy to genomics, the study of genes. Understanding the structure and function of each protein and the complexities of protein-protein interactions is becoming critical to the development of effective diagnostics, disease treatments and more importantly, degenerative disease prevention including eye disease.

Our genes are formed from microscopic double-strands of deoxyribonucleic acid (DNA). They are dependent on adequate nutrition for their structure and activity. By appropriately switching on and off (this is called transcription in the genome research world) our genes direct the behavior of our body's 60 trillion cells. Many genetic researchers consider our genes to be the Rosetta stone of health and disease.

A reclusive Russian mathematician, Grigori Perelman, used the equations of Ricci flow (a process by which topological regions of high curvature flow into regions of lower curvature) to finally prove the daunting 100 year old Poincare Conjecture - arguably one of the most famous unsolved math problems in the world.

The renaissance ophthalmologist, Juan Murube, MD, PhD, Professor of Ophthalmology, University of Alcala, Madrid, Spain, president of the International Society of Dacryology and editor of the Sources in Time section of the peer-reviewed journal The Ocular Surface, wrote a most interesting article in the January 2007 edition called The Ocular Surface and Its Symbolism. This week our Friday Pearl column addresses Dr. Murube’s brilliant literary enfeoffment to his readers.
