Abstract

Introduction: Strabismus is misalignment of the eyes in which both are not simultaneously directed at the object of regard. It is usually attributable to refractive, sensory, organic, anatomic, motor or innervation causes. The global prevalence varies and ranges from 1 - 5%. Though strabismus is a common presenting ocular problem, there are limited data in the study area about the prevalence and associated factors. The purpose of this study was to determine the prevalence and associated factors of strabismus among kindergarten school children in Gondar city. Methods: School based cross-sectional study design and Multistage random sampling technique was applied to select 848 study participants. The data was collected by semi-structured questionnaire and through eye examination with different ophthalmic instruments. Data was entered into Epi-info version 3.5.1 and analyzed using statistical package for social sciences version 20. Bivariable followed by multivariable binary logistic regression was fitted to test the strength of association with the variable and variables with P value < =0.05 were considered as statistically significant. Result: A total of 784 study subjects were included in this study, giving a response rate of 92.5%. The median age was 6 (+/-5.6) years. The overall prevalence of strabismus was 3.1% [AOR 95% CI: 1.8%-4.2%]. Prematurity [AOR=2.8 (95% CI: 1.0-8.2)], parents with strabismus [AOR=5.8 (95% CI: 1.5-22.6)] and children with refractive error [AOR=16 (95% CI: 5.4-48.1)] were significantly associated factors with strabismus. Conclusion: The overall prevalence of strabismus in this study was within the range of the global magnitude. Prematurity, parents with strabismus and children with refractive error were independently and significantly associated with strabismus. As vision loss and amblyopia are the major complications of strabismus, early school vision screening is important.
