How to create a Cutting Edge Optometric Retina Practice:• Understand the importance of macular pigment and triple
carotenoid macular enhnancement therapy in eye and macular health.• Define macular pigment and its properties.
• Understand that to enhance macular pigment requires supplementation with all three carotenoids(Mezozeaxanthin, Lutein and Zeaxanthin.)
• Understand why supplementation with all 3 carotenoids is neccessaryin our patients and why diet or supplementation with 1 or 2 carotenoids is inadequate.
• Understand how dark adaptation can be used to detect early macular degeneration as a measure of RPE 65 function
• Understand how triple carotenoid therapy is an oral anti-VEGF.
• Learn from cases using triple carotenoid therapy.
Objective- Triple Carotenoid/macular pigment enhancement therapy

Retinal BLINDNESS
AMD* 2010, the World Health Organization estimated 5% of world’s blindness was due to AMD.* Overall, 4.41 million people worldwide are estimated blind or visually impaired from AMD.* Leading cause of blindness over 55 in US developed world* More cases of AMD than Alzheimers, Breast Cancer and Parkinsons combined* Affects 1 in 5 families.
DR*Leading cause of new cases of blindness in US adults ages 20-74 years. *Prevalence.
• ≥40 years of age with diabetes: 28.5%• Type 1 with 20-30 years’ duration: 95%• Type 2 with ≥16 years’ duration: 60%

Laser reduces VEGF• Laser kills retinal cells which
reduces oxygen consumption by retina and reduces relative hypoxia.
• Reducing relative hypoxia reduces VEGF stimulation.

• Early monitoring By Optometrists can lead to rapid referral to a retina specialist at first sign of diabetic retinopathy.
• Anti-VEGF therapy standard of care for all forms of diabetic retinopathy.
• An optometrist in close realtionship with a retina specialist can prevent blindness in diabetic patients.
