【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 evaluate the risk of amblyopia in preterm infants with 0 ~ 2 years old using Suresight vision screening instrument, and to provide theoretical and practical evidence for the prevention and treatment of visual acuity and amblyopia in premature infants. 【Methods】 A total of 264 premature children without retinopathy were selected in our hospital from December 2009 to December 2010 and divided into 6 months, 9 months, 12 months, 18 months and 24 months according to the corrective age Age, a total of 5 groups, the same period randomly selected 50 normal full-term children of all ages as the control group, with reference to the previous study [1] in the development of amblyopia at high risk of screening populations and suspicious populations using Suresight vision screening instrument to measure binocular diopter , Analysis of the risk of amblyopia. 【Results】 Hyperopia was observed in preterm infants aged 0 ~ 2 years. The incidence of moderate and severe astigmatism and anisometropia was higher than that of full - term infants. The incidence of amblyopic asymptomatic children and suspicious children in each age group was higher than that of full - Prominent difference in age. 【Conclusion】 The incidence of amblyopia in preterm infants with 0 ~ 2 years old is higher than that of full - term infants. It is suggested that vision screening should be carried out regularly from 6 months old in preterm infants, visual acuity monitoring should be monitored, refractive errors should be corrected, the incidence of amblyopia reduced, Prevention and control work.
