学龄前儿童屈光状态调查分析

Survey of refractive state of preschool children

目的了解学龄前儿童屈光状态,促进学龄前儿童视觉保健的普及。方法采用美国伟伦Suresight最新屈光筛查仪对本院门诊体检学龄前儿童进行屈光筛查,对1 745名儿童进行屈光类型和散光类型分析。结果共检查了3 490眼,屈光类型分析显示,单纯近视1眼,正视74眼(2.1%),单纯远视1 072眼(30.7%),单纯近视散光44眼(1.3%),单纯远视散光156眼(4.5%),复性近视散光13眼(0.4%),复性远视散光2 034眼(58.3%),混合散光96眼(2.8%);散光类型分析显示,逆规散光431眼(18.4%),顺规散光1 700眼(72.6%),斜轴散光212眼(9.0%)。结论学龄前儿童屈光类型以复性远视散光为主,其次为单纯远视;散光类型以顺规散光为主。

Objective To evaluate the refractive state of preschool children and promote universal vision care in preschool children. Methods Refrangibility was detected in 1 745 preschool children using Suresight hand held refractometer and the types of refraction and astigmatism were analyzed. Results A total of 3 490 eyes were checked,in which 1 eye was simple myopia,74 eyes （2. 1 % ） were emmetropia, 1 072 eyes （30.7 % ） were simple hypermetropia, 44 eyes（ 1.3 % ） were simple myopic astigmatism, 156 eyes （4.5%） were simple hyperopic astigmatism,13 eyes （0.4%） were compound myopic astigmatism,2 034 eyes （58.3%） were compound hyperopic astigmatism, 96 eyes （2.8 % ） were mixed astigmatism. Astigmatism type analysis showed that 431 eyes （18.4% ） were indirect astigmatism,1 700 eyes （72.6%） were astigmatism with rule,and 212 eyes （9.0 %） were oblique astigmatism. Conclusion Compound hypermetropic astigmatism is predominant in the reflection types in preschool children followed by simple hypermetropia. In astigmatism,astigmatism with rule is the most.
