摘要
目的了解南宁市学龄前儿童的视力、屈光度发育状况,为儿童眼病预防措施的制定提供依据。方法采用整群随机抽样方法,选取南宁市3～6岁儿童2 304名,使用标准对数视力表进行视力检测,自然瞳孔下用SureSightTM手持式自动验光仪测定屈光状况。结果 2 304名学龄前儿童的眼视力≥1.0的比例为30.0%,视力不良的总检出率为7.2%。视力不良检出率随年龄增长而下降(P<0.05)。视力不良检出率在近视儿童中最高,轻度远视儿童中最低(P<0.01)。散光度≥0.75,≥1.50,≥2.50 D组学龄前儿童患视力不良的风险分别是散光度<0.75 D组的3.217,7.744和12.892倍。弱视检出率为2.78%。结论学龄前儿童视力不良检出率高,且随年龄的增长而降低,随散光度增加而增高。应及时矫正学龄前儿童散光,以预防视力不良的发生。
Objective To investigate the vision, refractive error and astigmatism in Nanning preschool children, and to provide evidence for the preventive measurement. Methods Totally 2 304 preschool children aged 3-6 years old were selected by using cluster random sampling method, the refractive status were determined using SureSight autorefractor without cycloplegia and the visual acuity were tested with standard logarithmic visual acuity chart. Results The proportion of eye with visual acuity 1.0 or more was 30.0%. The prevalence of poor visual acuity （ ≤0.5 ） was 7.2% and was decreasing with age （ P〈0.05 ）. The preva- lence of poor vision was higher in children with myopia, lower in children with mild hyperopia. The risk of poor visual acuity inci- dence in astigmatism ≥0.75D, ≥1.50D and ≥2.50D group were 3. 217, 7. 744 and 12. 892 times of astigmatism 〈0.75D group. Prevalence of amblyopia was 2.78%. Conehlsion Prevalence of astigmatism is high in Nanning preschool children and decreases with age. The risk of poor acuity is increasing with respect to increasing astigmatism magnitude. It indicates that the astigmatism of preschool children should correct as early as possible for prevention of amblyopia.
