Abstract

Purpose : To determine the prevalence of strabismus and associated risk factors in southeastern Brazil

Methods : This cross-sectional population-based study used a probabilistic and systematic sample between the years 2004 and 2005. The sample was randomly selected from 7,655 individuals living in nine municipalities in a southeast region of Brazil. A subsample of interested individuals aged from 1 to 12 years old was selected. Data were collected on visual acuity, evaluation of ocular alignment (Hirschberg test, simple and alternate cover test) and refractive error. Strabismic individuals (strabismus group) were compared to orthotropic individuals (orthotropia group) from the same population to analyze risk factors linked to the heterotropias

Results : A total of 1852 individuals were enrolled in the study. There were 30 individuals with strabismus indicating a prevalence of 0.81% for strabismus in this population. Hyperopia was present in 40% of the strabismus group and 6.85% of orthotropia group. Astigmatism was detected in 6.67% of the strabismus group and 18.12% of the orthotropia group. There were 3.33% myopes in the strabismus group and 14.82% myopes in the orthotropia group. Amblyopia was detected in 6.67% of the strabismus group and 0.19% of the orthotropia group. Significant anisometropia was present in 0.27% of the orthotropia group and in none of the strabismus group. Moderate anisometropia was present in 8.33% of the strabismus group and 4.37% of the orthotropia group

Conclusions : The prevalence of strabismus in the southeast region of Brazil was 0.81%. Strabismic individuals had more hyperopia than individuals with no deviation. Amblyopia, and moderate anisometropia were associated with strabismus
