Eye Diseases
• Glaucoma• Macular Degeneration• Cataracts• Myopia• Macular Degeneration• Retinopathy
Top Causes of Blindness World-Wide (WHO)
• 1) Cataracts 47.9%• 2) Glaucoma 12.3%• 3) Macular Degeneration 8.7%• 4) Corneal Opacities 5.1%• 5) Diabetic Retinopathy 4.8%
Vision Problems Cost USA Billions (Prevent Blindness America)
• Refractive Error $16.1 Billion• Cataracts $10.7 Billion• Vision Problems $10.4 Billion• Physical Disorders $8.9 Billion• Retinal Disorders $8.7 Billion• Glaucoma $5.8 Billion
Eye Anatomy
Eye Anatomy
Cardiovascular Disease: DM & HTN
Myopia Risk Factors?
• Insufficient sunlight,?Vitamin D• Nearwork/Literate vs. Illiterate/Hunter
Gatherers• Insulin, *IGF-1, Elevated Glucose• Genetics
Cordain,Thorne
Glaucoma Risks
• Lifestyle – Cardiovascular• Inflammation: (NTG), Cardiovascular• Low and High Blood Pressure, Blood Loss• Genetics• Magnesium, Gingko vs. High Calcium,Iron
Cataracts
• NSC and Cortical blood sugar, UV• Vitamin C?
A(R) MD –Risk Factors
• Control: Diet – Lutein, Zeaxanthin, MPOD (Macular Pigment Optical Density), Fish Gently Cooked, -Smoking, Excess UV, Acid Reducing Drugs, Leaky Gut
• Can’t Control: Age, Family History • Dry AMD – cone photoreceptors degenerate,
slowly progressing• Wet AMD – macula stops working so fragile
blood vessels grow and leak (CNV)
Wet AMD with CNV
A – Normal maculaB- Early Dry w/ DrusenC – Advanced dry w/ Geographic AtrophyD- Disciform Scar
Cognition
• Levels of L & Z in brain and MPOD correlate to global cognitive function in healthy elderly.
• Centenarian data correlates with memory retention, verbal fluency, dementia
• 4 month study double blind supplement (DHA + lutein) showed improved verbal fluency and memory
• MPOD increases with supplementation
Contrast Sensitivity
What to Eat: Ancestral Foods with FAT to increase
• 2 egg yolks /day (unless egg allergy) • 1 cup greens/day (collard, kale, spinach, Swiss,
chard, mustard greens, turnip greens etc.) with FAT to increase absorption/day
• 1 pound oily wild fish with/skin preferably salmon or 3 tins of sardines/wk or lemon-flavored Norwegian Fish Oil/FCLO – about 1-2g/ day (combined DHA/EPA)
Lutein & Zeaxanthin• Daily Ratio: 10 mg L to 2 mg Z (5:1 ratio)
though in nature typically 2:1• Main Carotenoids found in both mac & lens• L more affinity for rods (peripheral,
movement), Z for cones (color, central)• Z is a stereoisomer of Lutein
Top Foods L & Z per 100 g (cup)• Nasturtium (yellow flowers 45 mg)• Kale 22-32 mg (cooked more)• Spinach 10-20 mg (cooked more)• Turnip Greens,Collards, Chard 12-18 mg• *4 Egg Yolks (1 mg) more Bioavailable!
Structures
Factors Affecting Bioavailability
• Age, Body Comp, Gender, Malabsorption of Fats, Alcohol, Smoking, Liver or Kidney Disease
Food for Thought
• You can spend time and money cooking, and grocery shopping or sitting in waiting rooms of hospitals and doctors’ offices and pharmacies
• You can spend money on vitamins/minerals or drugs/surgery
• You can spend money on good quality food or spend it on booze, eating out, cable, etc.
• You can hike, stretch, walk, lift weights, do some ancestral activities or be in pain
Summary
• Eat a variety of real food to optimize nutrition• Take supplements as necessary • Get adequate RElaxation, REst, Sleep,
socialization, Sunlight, Testing (RE)2S3T)• Seek help with a functional medicine
practitioner if Dr. Google doesn’t help
