ABSTRACT

@#AIM: To investigate the incidence of amblyopia in preschool children and correlation factors in Bao'an District of Shenzhen so that to provide possible basis for the prevention of regional amblyopia. <p>METHODS: Totally 818 preschoolers with visual acuity screening were selected and studied from June 2017 to February 2018 in our Hospital. The incidence of amblyopia in children was recorded with the amblyopia diagnostic criteria and they were treated as observation groups. The others were treated as controls. The single factor and multivariate Logistic regression analysis were performed for the two groups. <p>RESULTS:The incidence of amblyopia in preschool children in Bao'an District of Shenzhen was 5.7%(47/818). Among them, ametropic amblyopia was the most common(63.8%), the second was anisometropic amblyopia(21.3%), the third was strabismic amblyopia(12.8%)and in the end was form deprivation amblyopia(2.1%). By single factor analysis: there were statistically significant differences between two groups for the correlation factors of gestational age, gravidity and parity history, gestational weeks and nearsightedness(amblyopia)family history(<i>P</i><0.05). By multivariate Logistic regression analysis: the older gestational age, more gravidity and parity, shorter gestational weeks and positive nearsightedness(amblyopia)family history were the highest risk factor for children with amblyopia(<i>P</i><0.05). <p>CONCLUSION: The incidence of amblyopia in preschool children in Bao'an District of Shenzhen is high and it should be taken seriously. In the meantime, there are many influencing factors. But comprehensive preschool vision screening is an effective method for early discovery, early diagnosis and early treatment.
