Incidence and types of childhood exotropia: A population-based study

To determine the incidence and types of childhood exotropia in a defined population. Retrospective, population-based cohort. All pediatric (or=10 prism diopters) from January 1, 1985 through December 31, 1994. The medical records of all potential patients identified by the resources of the Rochester Epidemiology Project were reviewed. Incidence and types of childhood exotropia. Two hundred five cases of childhood exotropia were identified during the 10-year period, yielding an annual age- and gender-adjusted incidence of 64.1 (95% confidence interval: 55.2-72.9)/100,000 patients younger than 19 years. This rate corresponds to a prevalence of approximately 1.0% of all children younger than 11 years, with a significant decrease in the incidence during the second decade of life (P
