title: Astigmatism in Zuni and Navajo indians.
abstract: Data provided by a practicing optometrist in Gallup, New Mexico indicate a greater than expected frequency of astigmatism among first- and second-grade Zuni and Navajo Indian children. Zuni children displayed a greater frequency of high astigmatism (3.00 D) than Navajo children. In an effort to understand the etiology of this prevalence of high astigmatism, a study of corneal astigmatism in 22 Zuni families was undertaken. The results suggest both genetic and environmental causes. A very high frequency of albinism was also observed among the Zuni.
