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.

How to create a Cutting Edge Optometric Retina Practice:• Managing diabetic retinopathy the state of the art.

• Describe how laser reduces VEGF and results in reduction of DME.

• Understand why anti-VEGF is the standard of care for DR and DME.

• Summarize the important trials that demonstrated anti-VEGFs efficacy for DME.

• Comprehend how PDR results in true blindness with traction detachment and Vitreous hemorrhage.

• Recognize the surgeries to restore vision in end stage PDR.

How can you Prevent AMDHow does nature protect the macula?

• DRY– Filter Blue Light

• External • Internal

– Anti-oxidant– Anti-Inflammatory

• Wet– Stop VEGF upregulation

Pigment is NATURES NATURAL PROTECTANT
