The last Friday Pearl of the year addresses the 2005 American Academy of Ophthalmology's series of guidelines called Preferred Practice Patterns (PPP). These patterns identify characteristics and components of quality eye care for the purpose of detecting and diagnosing vision, health, or life-threatening disease.

The Lewin Group was commissioned in early 2005 by the Dietary Supplement Education Alliance (DSEA) to critically review the research literature concerning Omega-3 fatty acids, lutein and zeaxanthin. As the population lives longer, reducing the level of disability caused by age-related diseases is becoming more important. Activities central to independent living, which include reading, driving, and writing, are considerably impaired through the loss of central vision due to AMD.

For the non-scientists, meta-analyses combine similar small studies together in an attempt to better assess the effects of a treatment. Meta-analyses are often considered the final word on the effects of those treatments, although there are serious limitations to this approach. When studies have different designs or inclusion parameters, deciding which studies to combine and which to leave out ...

A paradoxical effect of certain genes associated with type 2 diabetes, Alzheimer's and macular degeneration is linked in various studies to elevated homocysteine level, which is linked back to vitamin B6, B12 and folate deficiency. The oral insulin medications prescribed today for most type 2 diabetics is metformin and glyburide: both further inhibit normal absorption of vitamin B12 and folate.

Controlling oxidative stress (free radical damage) is a pivotal factor for chronic degenerative diseases of the eye and 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.

The positive ions associated with warm dry high-wind storms like the one that blew over the Colorado Rocky Mountain Front Range this week (84 miles per hour winds in Colorado Springs) are suggested in the literature to dramatically contribute to dry eye symptoms and other maladies.

Curcumin is a dietary compound with diverse antioxidant, anti-inflammatory and anti-carcinogenic effects. The strong anti-oxidative activity in curcuminoids, the main yellow pigments in Curcuma longa (turmeric), have been used widely and for a long time in the treatment of chronic inflammation in indigenous medicine.

The American Academy of Ophthalmology annual meeting proved to be a great launching pad for two new Biosyntrx products: Zeaxanthin4 and ZoOmega-3. Peer-reviewed science strongly supports the use of high-quality concentrated supplemental Omega-3s on days that cold water fish is not consumed, and zeaxanthin science continues to strongly suggest that the central macula preference is for zeaxanthin, not lutein.

At first glance, a National Library of Medicine search shows literature suggesting increased bleeding time with Ginkgo biloba. This is of extreme concern to many, including macula degeneration patients. However, almost all titles listed are anecdotal letters to journals, not evidence-based science. The well-meaning letters almost never address the amount of Ginkgo the bleeding patient was taking, nor do most of the published letters include a list of the other prescription and OTC medications the patient with a bleed was ingesting.

Ocular allergy can be broadly classified into four disease subcategories: seasonal allergic conjunctivitis (SAC), perennial allergic conjunctivitis (PAC), vernal keratoconjunctivitis (VKC), and atopic keratoconjunctivitis (AKC). It is estimated that over 20% of the general population suffers from some form of ocular allergy. Of those, over 90% have SAC, PAC, or both.
