目的探讨早期视力干预对学龄前儿童视力的影响。方法选取4家城乡幼儿园儿童分别作为观察组和对照组。其中观察组儿童312人实行早期视力干预,对照组儿童312人不采取任何干预措施,干预前后开展视力检查和父母问卷调查,1年后比较两组儿童视力水平及行为差异。结果干预后观察组儿童视力不良率由干预前的12.18%下降至7.37%(P<0.05);干预后观察组儿童视力不良率(7.37%)明显低于对照组(12.50%)(P<0.05);干预后观察组儿童行为习惯优于对照组(P<0.05)。结论早期视力干预对降低学龄前儿童视力不良的发生效果明显,值得推广应用。
Objective To explore the effect of early vision intervention on preschool children’s visual acuity. Methods Four kindergartens and children in urban and rural areas were selected as the observation group and the control group respectively. Among them, 312 children in the observation group had early visual acuity intervention. 312 children in the control group did not take any intervention measures. Before and after the intervention, they performed visual acuity test and parental questionnaire survey. One year later, the visual acuity level and behavioral difference of the two groups were compared. Results The rate of poor eyesight in observation group decreased from 12.18% before intervention to 7.37% (P <0.05), and the rate of poor eyesight in observation group was significantly lower than that in control group (7.37% vs 12.50%, P 0.05) ). After intervention, the behavior habits of observation group was better than that of control group (P <0.05). Conclusion Early visual acuity is effective in reducing the incidence of poor eyesight in preschool children and is worth popularizing and applying.
