AIM: To explore the risk factors of strabismus in preschool children.

METHODS: The clinical data of 1 926 preschool children who were hospitalized in Chongqing General Hospital of armed police from July 2009 to December 2015 were analyzed retrospectively. Among them, the children with strabismus were included in the strabismus group(n=186)and the children with normal vision were included in the normal group(n=1 740). The single factor and multi factor Logistic analysis were conducted on the clinical data of the two groups.

RESULTS: Birth weight, Apgar score and gestational age were independent risk factors for preschool children's strabismus(P<0.05), and Apgar score had the highest risk \〖OR(95% CI): 6.336(2.180-18.416)\〗.

CONCLUSION: Birth weight, Apgar score and gestational age are independent risk factors for preschool children's strabismus. Pregnant women should pay attention to prenatal care and try to give birth at full term to avoid the risk factors of children's strabismus. At the same time, regular visual screening of preschool children should be strengthened and appropriate interventions should be given.
