早产儿童学龄前的屈光状况分析

Preschool refractive status of preterm children

摘要:

目的 探讨早产儿童学龄前的屈光状况。方法 选取2009 年2 月-2010 年1 月于青海大学附属医 院接受体检的3 岁早产儿193 例（386 眼）作为早产组，并随机选取同期到该院接受体检的3 岁足月儿190 例 （380 眼）作为足月组，比较两组儿童学龄前的屈光度和屈光状态。结果 两组儿童的等效球镜值、球镜度数 及柱镜度数比较有差异（P <0.05）。两组儿童远视率、正视率及近视率比较有差异（P <0.05）。两组5 和6 岁儿童散光率比较有差异（P <0.05）。结论 早产儿童学龄前的屈光状况较差，更易发展为近视或散光，临床 上应加强对早产儿屈光检查的力度，定期进行随访及干预。

Abstract:

Objective To study the preschool refractive status of premature children. Methods A total of 193 premature children at the age of 3 years (386 eyes) having physical examination in our hospital from February 2009 to January 2010 were selected as the preterm group, and 190 3-year old term children having examination (380 eyes) at the same period were randomly selected as the full-term group. The preschool diopter and refractive status were compared between the two groups. Results The spherical equivalent, spherical and cylindrical degree were significantly different between the two groups (P < 0.05). The rates of hyperopia, emmetropia, myopia and astigmatism were significantly different between the two groups (P < 0.05). Conclusions Preterm children have poor preschool refractive status, and are more likely to develop myopia or astigmatism. Refractive examination of preterm children should be strengthened in clinic, and regular follow-up and intervention should be carried out.
