Introduction • AMD is the leading cause of vision loss in Americans over the age of 60 • Advanced AMD is the leading cause of vision loss and irreversible blindness worldwide in those over the age of 50 • As many as 11 million Americans have some level of AMD UPDATE ON AMD 2021 – Expected to increase to nearly 22 million by 2050 • More than glaucoma (2.2 million) and DR (7.7 million) Steven Ferrucci, OD, FAAO COMBINED Chief, Optometry Sepulveda VA Professor, SCCO/MBKU 1 2 Introduction Dry AMD • Exciting time to be interested in AMD • Currently mainstay treatment for Dry AMD revolves around prevention of progression through vitamins, nutrition and lifestyle • Many new treatments now available for AMD changes – Years ago, we had nothing at all to offer patients with AMD – Rheophoresis, Laser, Anecortave Acetate did not prove effective – Smoking #1 modifiable risk factor for getting AMD as well as its • Current Treatments progression! • Potential Treatments • One study showed 90% of pts with AMD were not advised to quit smoking • Early detection of conversion from dry to wet may result in better • New Diagnostic Equipment treatment for patients 3 4 AREDS AREDS 2 • First large scale study looking at nutrition and ocular health • AREDS 2: Enrollment ended June 2008 with ≈4200 patients followed • 3640 pts followed on average for 6.3 years for six years – Effect of lutein, zeaxanthin and omega 3 on AMD – Results released October 2001 – Effect of eliminating beta carotene on AMD • Results showed that 25% risk reduction to developing advanced – Effect of reducing zinc on AMD AMD in pts with intermediate (stage 3) AMD or worse – Effect of supplements on cataracts 500 mg vitamin C 400 IU vitamin E – Validate the AMD scale from original AREDS 15 mg vitamin A (25,000 IU beta carotene) 80 mg zinc • Results released May 5, 2013 2 mg copper 5 6 1 “Wet” AMD AREDS2 Formulation • Neovascular “wet” AMD • Vitamin C (500 mg) – Mainstay of treatment consists of serial intravitreal injection of anti-VEGF agents Anti-VEGF Pegaptanib Ranibizumab Aflibercept Brolucizumab Bevacizumab • Vitamin E (400 IU) Agents (Macugen®) (Lucentis® ) (Eylea® ) (Beovu® ) (Avastin® ) FDA approval 2004 2006 2011 2019 Not approved • Beta Carotene (15 mg) ANCHOR VIEW HAWK Pivotal studies VISION MARINA CATT 1 and 2 HARRIER • Lutein (10 mg)/Zeaxanthin (2 mg) IVAN – VEGF inhibitors have demonstrated improved visual and anatomic outcomes • Zinc (80 mg zinc oxide) compared with other therapies VEGF = vascular endothelial growth factor. • Copper (2 mg cupric oxide) AAO.
