Optometry Times Primary Care Optometry News Optometric Office Review of Optometry It emphasizes the therapeutic relationship and makes use of both appropriate conventional and alternative therapies. Life expectancy increased, but quality of life is proving to be dismal. 1.9 million people are living into their 90’s. This number has tripled in the past 20 years. A philosophy that neither rejects conventional medicine nor accepts alternative therapies uncritically By 2050, there will be 9 million people living this long. We have a long “life span” but a shorter “health span”. We die too slowly from chronic processes like stroke, heart disease, cancer, diabetes, Alzheimer’s and Parkinson’s. Use of natural, effective, less-invasive interventions whenever possible Integrative Optometry follows these same principles. Age-adjusted Incidence Rate 1000 800 600 Females Males 400 200 Blindness:1 million over age 40 Visual impairment: 2.4 million Dry Eyes: 12+ million Macular Degeneration: 10.6 million Cataracts: 20.5 million Diabetic Retinopathy: 5.3 million Glaucoma: 2.2 million (2 million undiagnosed) These numbers will double in 20 years! ALL ARE LINKED TO NUTRITIONAL DEFICIENCIES 0 1973 1999 1 Total financial burden of major adult visual disorders is $51.4 billion $6.8 billion for cataracts $5.5 billion for refractive error $2.9 billion for glaucoma $575 million for AMD $493 million for diabetic retinopathy Prevention is less expensive!

For those who initially had early AMD (Category II), did NOT slow the disease's progression to intermediate AMD. Can people with early stage AMD take the AREDS formulation to help prevent the disease from progressing to the intermediate stage? There is no apparent need for those diagnosed with early stage AMD to take the AREDS formulation. The study did not find that the formulation provided a benefit to those with early stage AMD. If you have early stage AMD, a comprehensive dilated eye exam every year can help determine if the disease is progressing. If early stage AMD progresses to the intermediate stage, discuss taking the formulation with your doctor. National Eye Institute Recommendation on Macular Degeneration “Reduces the risk of advanced AMD” The effect was in 25% of the study population with stage III AMD. Slowed progression from stage III to IV. Did not prevent AMD. Did not reverse AMD. Did not halt progression of AMD. 3 Started in 2007 The population will involve at-risk patients as well as patients with advanced AMD 1 gm EPA/DHA from Salmon Oil Both lutein (10mg) and zeaxanthin (2mg) 10 mg lutein, plus 2 mg zeaxanthin, plus 1 gm EPA/DHA The original AREDs formula ◦ No beta-carotene ◦ Less zinc A placebo????

However, because of potential increased incidence of lung cancer in former smokers, lutein + zeaxanthin could be an appropriate substitute in the AREDS formulation.” Placebo Original AREDS formula Lutein/Zeaxanthin Lutein- 10mg Zeaxanthin- 2mg Formulations Vitamin C Vitamin E EPA/DHA L/Z and EPA/DHA EPA- 650mg DHA- 350mg AREDS plus L/Z and EPA/DHA Beta-carotene Zinc Oxide Cupric Oxide 1 (Original) 500 mg 400 IU 15 mg (25,000 IU) 80 mg 2 mg 2 500 mg 400 IU 0 mg 80 mg 2 mg 3 500 mg 400 IU 0 mg 25 mg 2 mg 4 500 mg 400 IU 15 mg (25,000 IU) 25 mg 2 mg Formulation: Beta Carotene- 15 mg (25,000 IU) Vitamin C- 500 mg Vitamin E- 400 IU Zinc (oxide)- 80 mg ?

Both groups significantly improved some measures of visual function, including glare recovery, contrast sensitivity and visual acuity. 5,205 women without AMD, average age 63 All were permitted to take multivitamins with B-6, B-12 and folate up to, but not exceeding, recommended daily allowance (RDAs). “Vitamin D Status and Early Age-Related Macular Degeneration in Postmenopausal Women” Those getting the B-6, B-12 and folate supplements received much larger amounts: 2.5 mg of folate (folic acid), 50 mg of vitamin B6 (pyridoxine) and 1 mg of B12. Conclusion: High serum 25(OH)D concentrations may protect against early AMD in women younger than 75 years. After an average of 7.3 years of treatment and follow-up, there were 55 cases of AMD in the combination treatment group and 82 in the placebo group (relative risk, 0.66; 95% confidence interval, 0.470.93 [P = .02]). For visually significant AMD, there were 26 cases in the combination treatment group and 44 in the placebo group (relative risk, 0.59; 95% confidence interval, 0.36-0.95 [P =.03]) Amy E.

It doesn’t mean the absence of fences or enclosures in general. Birds that qualify as cagefree can still be packed tightly into an overpopulated and darkened barn. FreeFree-Range: Required to have access to the outdoors—but that may amount to a narrow patch of dirt. Access to it can be a tiny door cut into the back of the shed, which in an overcrowded barn stuffed with hens, the birds may not ever notice, let alone use. Organic: Birds are antibiotic and hormone-free, in addition to being provided with access to the outdoors. Still, some organic farms abuse the system by housing their hens in overcrowded sheds—with a small, unused door. Certified Humane: According the Humane Society, even this certification allows for farmers to house chickens indoors at all times if they choose, and also permits beak cutting. A similar term, "American Humane Certified" allows laying hens to be caged. What to Look for Instead PasturePasture-raised is a label used increasingly by smaller, sustainable chicken farms to indicate that they legitimately raise their birds outside, on an actual pasture. Hens also enjoy access to shelter when they choose to take it, and they’re raised without the use of harmful chemicals or painful procedures. Not a naturally occurring nutrient in traditional diets Is generated from the metabolism of lutein Does not convert from zeaxanthin Meso-zeaxanthin Zeaxanthin Lutein “In the US the presence of MZ in the macula is not likely due to dietary sources, although this a possibility when consuming eggs of chickens fed MZ” Lutein, zeaxanthin, meso-zeaxanthin content in egg yolk and their absence in fish and seafood.

Clinical Trial of Lutein in Patients With Retinitis Pigmentosa Receiving Vitamin A Eliot L. Berson, MD, et al Arch Ophthalmol. 2010;128(4):403-411 • 85% of all patients demonstrated an increase in MPOD 7 The second most abundant mineral in the body (calcium). Critical in most metabolic processes, including DNA replication. Zinc oxide is the type that was used in the AREDS studies, and the type which is still used by most of the formulators. Monomethionine zinc is the most bioavailable form of zinc and the only form that does not interfere with copper absorption. 80 mg of zinc oxide is too much for long term daily consumption. High concentrations of zinc have been found in subretinal pigment epithelial deposits, and have been associated with urinary tract disorders. Recommended daily intakes are: Infants: 5 mg Children:10 mg Women:12 mg Pregnant Women:15 mg Lactating Women:16 mg Men:15 mg The tolerable upper limit for zinc was set at 40 mg per day for adults over 19. Copper's presence in the food supply is ubiquitous. Because copper is a pro-oxidant when free and unbound, it can quickly generate free radicals. Copper appears to be one of the main environmental factors that trigger the onset and enhance the progression of Alzheimer's disease by preventing the clearance and accelerating the accumulation of toxic proteins in the brain. Vitamin E A 2005 study in the JAMA suggested that excessive (400 IU) Vitamin E can be deadly! A closer look shows that the isolated finding applied only to an older group of patients (over the age of 70), had a long history of heart disease, stroke or diabetes, and were also taking a combination of medications, including ACE inhibitors, calcium channel blockers, anti-platelet agents and lipid-lowering agents during the course of the study.

Deficiency results in bleeding gums, loose teeth, pinpoint hemorrhages, frequent infections, slow healing, cataracts(?) Overdose causes nausea, diarrhea Also shown to reduce bleeding and bruising Sodium ascorbate- easier on stomach One French study in 1942 of improved night vision of RAF pilots in WWII(??) Since the structure of anthocyanins is consistent with an ability to donate hydrogen atoms, it is powerful antioxidant. Anthocyanins have been shown to scavenge chemicallygenerated superoxide and nitric oxide radicals, as well as quench singlet oxygen. Keeps vitamin C in a reduced state- more effective Also a blood thinner, so moderation is suggested. A 24 month Italian double-blind AMD study showed an improvement of visual functions and fundus alterations in early AMD. Phototrop® is a combination of: ◦ ◦ ◦ ◦ DHA: increases cellular permeability EPA: anti-inflammatory CoQ10: cleans out the mitochondria (antioxidant) Acetyl-L Carnitine: drives CoQ10 across the membrane Omega 3 fatty acid derived from alpha-linolenic acid Abundant in the retina ◦ Highest concentration of any cell type in the body. ◦ Concentrated in the rod outer segments ◦ Constitutes 30-40% of total fatty acid in the retina/brain- far more than any other tissue.

Phytoalexins are antibacterial and anti-fungal chemicals produced by plants as a defense against infection by pathogens. Resveratrol has also been produced by chemical synthesis, and is sold as a nutritional supplement. Anti-cancer, antiviral, neuroprotective, anti-aging, antiinflammatory and life-prolonging effects have been reported.

PGE1 Reduce inflammation and inhibit blood clotting. Capable of reducing pain, swelling and redness associated with inflammation, particularly in mucosal tissues, which includes the eyes. Can only be produced by Omega-6 fatty acids PGE2 Are opposite of PGE1s but can only be produced by Omega-6 fatty acids, as well. PGE3 Are available from Omega-3 fatty acids The Omega-3 fatty acid, EPA, also plays an important anti-inflammatory role. It appropriately blocks the release of Omega-6 arachidonic acid, so without sufficient Omega-3s in the diet, chronic inflammation becomes one of the problems now linked to many degenerative diseases of the eye. Are pro-inflammatory mediators that constrict blood vessels, increase body temperature, and encourage blood clotting. These events are lifesaving when the body suffers a wound or injury, for without PGE2s, a person could bleed to death. However, in excess, this type of prostaglandin is harmful because it sets up a chronic inflammatory condition in the body. 14 Provide overall anti-inflammatory effect Increase fluidity of meibomian gland secretions Improve tear film quality and decrease evaporative loss Optimize function of goblet cells Is dry eye an indicator of systemic essential fatty acid deficiency or imbalance ?

Aragona, P., Bucolo,C., et al IOVS 2005; 46:4474-4479 Do not confuse all the processed food items that contain hydrogenated trans-fats with Omega 6 essential fatty acid intake. All fatty acids are destroyed by the hydrogenation process. The series one anti-inflammatory prostaglandins (PGE1s) from natural Omega 6s are more specific to mucosal tissues (eyes) than the series three prostaglandins (PGE3s) from Omega 3s. “Here are a few samples- see which one you like the best”. “Just go to the drug store and pick up some artificial tears”…….. 16 The aqueous humor, which feeds the lens, has the highest amount of Vitamin C of any fluid in the body (26x more than in serum). The lens has the highest concentration of protein of any organ. Recent studies have found significant amounts of lutein and zeaxanthin in the lens. Carbohydrate intake Water Content Protein Sodium Potassium Calcium Glutathione Higher ALA (omega-3 alpha-linolenic acid) intake is associated with a greater age-related change in lens nuclear density. BMI ◦ BMI > 30 or waist size > 35" is associated with two fold increase in prevalence of PSC opacities ◦ Diabetes increases the odds for PSC opacities 4-fold.

Am J Clin Nutrition 2000;72:1417-8) 17 Network Antioxidants •Lipoic Acid •COQ10 Network Antioxidants greatly enhance the power of one another. They are particularly effective in slowing down the aging process and boosting the body’s ability to fight disease. •Glutathione •Vitamin E Precursor to glutathione- an amino acid complex Glutathione is the “master” antioxidant Glutathione is destroyed by digestive process, therefore must be created internally. Glutathione is depleted in cataractous lenses •Vitamin C “…turmeric and curcumin are effective against the development of diabetic cataract in rats. Further, these results imply that ingredients in the study’s dietary sources, such as turmeric, may be explored for anti-cataractogenic agents that prevent or delay the development of cataract.” The presence of oxidative stress in selenite cataract development and its prevention by resveratrol support the possibility that high natural consumption of resveratrol in food can help prevent human senile cataract. “The effect of resveratrol in experimental cataract model formed by sodium selenite” Dogeney, S. et al Curr Eye Res. 2006 Feb;31(2):147-53.

N-acetylcarnosine (1%) Found in high concentrations in skeletal tissues. Addresses the anti-aging issues of cellular crosslinking, which contributes to cataract formation. Take with zinc. Topical anti-cataract eye drop Antioxidant, anti-glycating and chelating dipeptide, developed in Russia Precursor for L-carnosine Human study: 41% of participants showed improvement in visual acuity at 6 mos.(76 eyes) No subjects had worse vision at 24 mos. 18 NACA injections prevented cataract formation in rats GSH levels were significantly decreased but the rats that received NACA injections had these levels of GSH replenished. NACA inhibits cataract formation by: ◦ Limiting protein carboxylation ◦ Preventing lipid peroxidation ◦ Replenishing antioxidant enzymes In vivo inhibition of l-buthionine-(S,R)-sulfoximine-induced cataracts by a novel antioxidant, N-acetylcysteine amide The development of AMD and nuclear cataract are associated with a high dietary glycemic index. “…these foods may advance damage to the metabolically limited tissue of the lens by exposing this tissue to glucose for longer periods.” 1.

High GI Foods are those which are rapidly digested and absorbed and result in marked fluctuations in blood sugar levels. Low GI foods, by virtue of their slow digestion and absorption, produce gradual rises in blood sugar and insulin levels, and have proven benefits for health. smaller rise in blood glucose levels after meals diets can help people lose weight and can improve the body's sensitivity to insulin can improve diabetes control foods keep you fuller for longer can prolong physical endurance high GI foods help re-fuel carbohydrate stores after exercise www.glycemicindex.com “…this shows an association of consuming a diet rich in DHA with lower progression of early AMD.” In addition to the AREDS supplement, lower dGI with higher intakes of DHA and EPA was associated with reduced progression to advanced AMD. “Does eating particular diets alter risk of age-related macular degeneration in users of the age-related eye disease study supplements?” Chiu CJ,, et al Br J Ophthalmol. 2009 Jun 12.

Is essential to potentiate the insulin receptors Excessive amounts of chromium picolinate are now linked to cancer. Chromium polynicotinate is more effective than any other type of chromium, as it binds the elemental chromium to niacin. This provides a biologically active form of chromium, which is more absorbable in the body. Nutrient Density is a measure of nutrients provided per calorie of food, or the ratio of the amount of a nutrient in foods to the energy provided by these foods. Nutrient-dense foods are those providing substantial amounts of vitamins and minerals and relatively fewer calories. 25 THEN NOW Balance of saturated and unsaturated fats Overly saturated fats Complex carbohydrates Simple and refined carbohydrates High quality plant and animal protein Corn-fed beef and poor quality proteins Nutrient dense foods supply vitamins, minerals and phytochemicals that create antioxidants.

High Density Lipoprotein (HDL)-removes cholesterol from the cells and transports back to the liver. An enzyme that is required for electron transport in ATP synthesis (facilitates energy production at the cellular level) 95% of human body’s energy is generated this way!! Immune system support Provides antioxidative-bioenergetic balance Useful in maintaining energy levels Oxidative protection for cellular membranes and plasma lipoproteins Neuro-protective Low level linked to decreased cardiovascular function Decreased with statin use! Low Density Lipoprotein (LDL)- transports cholesterol and fat from the liver to the cells. Found in every cell of your body, especially in the membranes of these cells, where it helps maintain the integrity of these membranes, and plays a role in facilitating cell signaling Molecule for molecule, cholesterol can make up nearly half of the cell membrane. Also present in membranes of organelles inside the cells. About 25% of total body cholesterol is located in the brain!! Is the backbone of vitamin D (not really a vitamin) LDL is harmless. It becomes a problem when unstable free radicals oxidize it. When LDL settles on artery walls, the wall membranes release damaging free radicals. The resulting oxidized LDL draws white blood cells to the site. These form plaque and trigger inflammation of the endothelium. 50% Calcium 3% Cholesterol 26 Statin Statins only reduce cholesterol in one mannerinhibiting cholesterol production in the liver. Statins generally focus on lowering LDL but do little to improve HDL or lower triglyceride levels. They may lead to dangerous side effects - some people cannot take statins at all due to these side effects. Statins alone may not lower cholesterol to the desired levels. They deplete stores of CoQ10, which is a powerful antioxidant and necessary for proper cell wall development and cellular energy production.
