目的了解清城区学龄前儿童的视力状况。方法采用美国伟伦公司suresight视力筛选仪,于2009年对清城区68所幼儿园13755名学龄前儿童进行视力筛查;同时,回顾性总结分析该地区近5年学龄前儿童的视力发展状况。结果各年龄段视力异常检出率差异有统计学意义(2χ=177.44,P<0.05),视力异常随着年龄的增长而降低。2009年486名儿童存在视力不良,其中散光占77.16%,远视+散光占7.61%,远视占9.87%,近视+散光占2.26%,近视占3.08%;各类型视力不良差异有统计学意义(P<0.05)。3734名儿童存在视力问题。结论学龄前儿童的视力异常发生率虽有下降,但仍处于较高水平,必须引起各级地方政府、保健机构、幼儿园老师及家长的重视。
Objective To understand the visual acuity of preschool children in Qingcheng District. Methods The suresight vision screening instrument of American Weilun Company was used to screen 13,755 preschool children in 68 kindergartens in Qingcheng District in 2009. At the same time, the visual acuity of preschool children in the past five years was retrospectively analyzed. Results There was a significant difference in the detection rate of visual acuity among all age groups (2χ = 177.44, P <0.05). Visual abnormalities decreased with age. There were 486 children with poor eyesight in 2009, of which 77.16% were astigmatism, 7.61% were hyperopia and astigmatism, 9.87% were hyperopia, 2.26% were asymptomatic and astigmatism, and 3.08% were myopia. There were statistically significant differences in all kinds of visual acuity (P <0.05). 3734 children have vision problems. Conclusions Although the incidence of abnormal vision in pre-school children has dropped, it is still at a high level and must be paid attention to by local governments, health care institutions, kindergarten teachers and parents at all levels.
