【目的】 使用Suresight视力筛查仪分析0~2岁早产儿弱视发生风险,为早产儿早期开展视力筛查与弱视防治提供理论与实践依据。 【方法】 选取2009年12月-2010年12月在本院健康体检的无视网膜病变早产儿264人,按矫正年龄分为6月龄、9月龄、12月龄、18月龄、24月龄共5组,同期随机选取各年龄段50名正常足月儿作为对照组,参照前期研究^[1]中制定的弱视高危人群与可疑人群筛查标准,使用Suresight视力筛查仪测量双眼屈光度值,分析弱视发生的风险。 【结果】 0~2岁早产儿中高度远视、中重度散光与屈光参差发生率较足月儿高,各年龄组弱视高危儿童与可疑儿童发生率均较足月儿高,并在6月龄时就突显出差异性。 【结论】 0~2岁早产儿弱视发生风险较足月儿高,建议早产儿从6月龄开始定期进行视力筛查,监测视力发育,及时矫治屈光不正,降低弱视发病率,做好弱视的防治工作。

【Objective】 To analyse the risk of amblyopia among 0~2 years old premature infants by Suresight screening. 【Method】 Refraction was measured by Suresight screening at corrected age of 6 months,9 months,12 months,18 months and 24 months old in 264 preterm infants without retinopathy between December 2009 to December 2010. 50 full term infants age-matched were also included in the study as control groups. We analysed the risk of amblyopia in preterm infants with the high-risk and suspicious criterion established by suresight screening in our pre-study. 【Results】 Higher incidence of moderate and high-dgree hyperopia、moderate and high-dgree astigmatism、anisometropia were found on preterm infants than in age-matched full term infants. Also higher incidence of high-risk and suspicious children of amblyopia were found on preterm infants,especially at 6 months aged. 【Conclusions】 The risk of amblyopia is higher in premature infants.It suggests that vision screening should be performed at the age of 6 months old in preterm infants and vision monitoring should be given in their childhood,which will help to correct refractive error early and decrease the rate of amblyopia.
