AIM:To understand the epidemiology and related factors of strabismic amblyopia of students of primary school, and to provide guidances for the prevention and control strategy.

METHODS: A total of 600 cases of primary school students of Leshan City, Jiajiang County were given vision, oblique incidence and ocular and other screening. The prevalence rate of poor eyesight of strabismus, amblyopia prevalence rate of different sexes, ages were compared, and the degree of amblyopia and strabismus of children with different types of amblyopia and whether or not had stereoscopic vision were counted.

RESULTS:The prevalence rate of amblyopia and strabismus prevalence rate were respectively 4.0% and 2.5%; With the growth of all age, low vision of students was significantly decreased, the difference of comparison of low vision rate of each age had statistical significance(P<0.05), but different ages, strabismus prevalence of different sexes, amblyopia prevalence were compared, the difference had no significant differences(P>0.05); Ametropic amblyopia was the main type, accounting for 55.6%, and the degree of amblyopia mainly was light, moderate; ametropic amblyopia, most of ametropic amblyopia and strabismus had stereo vision, but there were no stereopsis of most of the strabismic amblyopia and all esotropia.

CONCLUSION:Ametropic is mainly type of amblyopia, the prevalence of relationship between the incidence of strabismic amblyopia of primary school students and sexes is not obvious, but the oblique amblyopia treatment effect, such as the establishment of stereoscopic vision and the age, eye position has a close relationship, should be early discovered, early treatment.
