  1. Common eye problems in American Indians/Alaskan Natives Steven L. Mansberger, M.D., M.P.H. Devers Eye Institute Portland, Oregon

  3. Topics • Studies in AI/AN • Northwest Tribal Vision Project • Results • Future Directions

  4. Most common causes of visual Impairment • Blacks/Whites: Macular Degeneration, glaucoma, uncorrected refractive error (Baltimore Eye Survey) • Hispanics: glaucoma, cataract, macular degeneration, diabetic retinopathy (LALES, Proyecto VER) • Whites: Macular degeneration (Beaver Dam Study) • Japan, Korea, India, Africa, Caribbean

  5. Northwest Tribal Vision Project • Purpose: • Pilot study: To determine the prevalence of eye diseases in NW Native Americans • To determine if a screening protocol is as accurate as a full eye exam in an ophthalmologist’s office • Funding: American Glaucoma Society, National Eye Institute, and Centers for Disease Control and Prevention (CDC)

  6. What is the Prevalence of Eye disease in Native Americans? • Vision is the second leading cause of impairment • Studies in Native Americans have been chart reviews or convenience Samples • Navajo/Pima: diabetic retinopathy, cataracts, and trauma • Alaskan Eskimos: angle closure glaucoma

  7. Glaucoma in AI/AN • Alaskan Eskimos: 0.6% (Arkell, 1987) • Northwest AI/AN: 6.2% (Mansberger, 2005) • Oklahoma AI/AN: 5.6% (Lee, 2005)

  8. Retinal Diseases in AI/AN • Diabetic Retinopathy • 6.0% (Mansberger, 2005) • 20.1% (Oklahoma, Lee, 2005) • ARMD • 16.9% (NW AI/AN, Mansberger, 2005) • 33.6% (Oklahoma, Lee, 2005)

  9. Proportion with Visual Impairment/Blindness • 6.9% (20/288) with visual Impairment of the better eye with correction (20/40 vision or worse) • 21% (61/288) visual impairment without correction • 0.9% (3/288) Blind in the better seeing eye (20/200 or worse) • Greater than U.S. population (Haymes, et al Ophthalmic Epi 2009)

  10. Differences Exist in AI/AN anatomy and Eye Disease • OD Vertical C/D = 0.48 +/- .18 (range 0.0-0.9) • One person (0.3%) had IOP > 21 mm Hg (95%CI=0-1.0%) • 15 (6.2%) participants had glaucomatous optic discs and visual fields (95%CI=2.1-7.8%). • None with an IOP greater than 20 mm Hg.

  11. Differences also exist within AI/AN ? Source: Genetree.com http://www.genetree.com/product/native-american-test.asp

  12. Summary • Vision problems are the second leading cause of impairment in AI/AN • Uncorrected refractive error, cataract, and retinal diseases were the most common causes of visual impairment • A rare form of glaucoma was more common in AI/AN • Differences in eye problems occur even between AI/AN in different regions • Research to determine the factors related to disparities in eye problems in AI/AN are needed
