Visual impairment and eye care among Alaska native people
2009
Purpose: To estimate the prevalence of visual impairment, eye disease and eye care in the Alaska Native (AN) population, by demographic and socioeconomic factors. Methods: Population-based cross-sectional study of 3,793 AN adults aged 18–94 years enrolled in the Education and Research Towards Health (EARTH) Study from March 2004–March 2006. Data on self-reported visual impairment, cataract, glaucoma, diabetic eye disease and previous dilated eye examinations were collected using audio computer-assisted self-administered questionnaires. Results: The unadjusted prevalence of self-reported visual impairment was 8.7% (95% confidence interval (CI): 7.9–9.7), cataract 5.9% (95% CI: 5.2–6.7), glaucoma 2.5% (95% CI: 2.0–3.0) and diabetic eye disease 1.3% (95% CI: 0.9–1.7). In all cases, age-sex adjusted prevalence estimates for the AN population were greater than available estimates for the general U.S. population. Prevalence of visual impairment and each eye disease increased with age (P < 0.01). Additional fact...
