Astigmatism, Amblyopia, and Visual Disability Among a Native American Population

Abstract

It is well documented that there is a high prevalence of both astigmatism and visual disability among some Native American peoples. As shown in Table 1, the prevalence of astigmatism ≥1 diopter (D) among Native American school-age children ranges from 30% to 87%, whereas the prevalence of astigmatism ≥1 D among urban school-age children ranges from 2% to 7%.
