Refractive Status Of Eastern Oklahoma Indian Population.

The Native American population in Eastern Oklahoma has a longstanding history of intermarriage with the caucasian population and has acquired a large variance of degree of Indian blood. The objective of the study was to observe the effect of intermarriages upon the unique refractive qualities of the Indian population. The refractive status of 456 eyes was recorded and compiled at Carl Albert Eye Cline (Indian Health Service) in Ada, Oklahoma. The study exhibits a refractive result closely patterned to a normative population. With-the-rule (WTR) astigmatism and myopia findings however, remained strongly attached to the welldocumented traditional Native American refractive characteristics. Further studies are necessary to eliminate some of the ambiguities of this topic.
