调查南京市江宁百家湖社区学龄前儿童的双眼屈光状态及同时视,分析学龄前儿童屈光状态的分布、屈光不正的患病情况及同时视情况。 方法:采用带状光检影镜,TSJ-IV型同视机在半暗室光线非散瞳下对南京市江宁百家湖社区7所幼儿园3~5岁儿童1352例的双眼屈光状态及同时视进行检查,其中男孩728例,女孩624例,对检查结果按屈光状态检查及同时视检查分类,并分别统计不同年龄组的结果。 结果:屈光状态检查中,学龄前儿童屈光不正率为13.35%,5岁~组屈光不正率最高,但各年龄组无统计学差异(P=0.408)。屈光不正眼中,3岁~、4岁~、5岁~年龄组远视、散光构成比有统计学差异(P=0.003),4岁~年龄组散光占比高于其他组。同时视检查发现视轴异常162例,占总人数12.01%。其中视轴向内偏斜角>+5°占96.30%,向外偏斜角>-5°占3.70%。3岁~、4岁~、5岁~年龄组视轴偏斜异常率比较有统计学差异,3岁~组异常率最高,视轴向内偏斜为主(P=0.001)。视轴偏斜异常162例,屈光状态以正视为主,占81.48%(132/162),视轴偏斜异常的学龄前儿童屈光不正的患病率与视轴正常的儿童屈光不正的患病率比较无统计学意义(P=0.125)。 结论:南京市江宁百家湖社区学龄前儿童屈光不正主要类型为散光和远视,双眼同时视检查异常以视轴向内偏斜为主。在半暗室光线下行非散瞳检影并同时行双眼同时视检查可作为幼儿园屈光状态及初级视功能检查的有效筛查手段。

To survey the refraction and binocular vision of preschool children in Jiangning-s Baijiahu district of Nanjing,and to analyze the distribution of refraction,the condition of ametropia and binocular vision. METHODS: Totally 1352 preschool children who had natural pupil in 7 kindergartens of Jiangnings Baijiahu district of Nanjing-were examined in the half-dark room by retinoscopy and-binocular vision instrument (type:TSJ-IV), including 728 boys and 624 girls. Refraction and binocular vision were statistically analyzed in different age groups.- RESULTS: The ratio of refraction error was 13.35%,which was the highest in 5-year-old group.There was no significant difference in those groups(P=0.408). The proportion of astigmatism and hyperopia was significant difference in-3- year-old group,4- year-old group,5 -year-old group(P=0.003),the ratio of astigmatism in 4-year-old group was significantly greater than that in other groups.162 children had binocular vision disorder,and the ratio of which was 12.01%,including 156 children (96.30%) with (range +6~+13°, >+5°),and 6 children (3.70%) with exotropia(range -6~-12°,>-5°)。There were significant difference in the ratio of binocular vision disorder in-three-groups,and the greatest in 3-year-age-group,mainly of esotropia(P=0.001).-Among these 162 children with binocular vision disorder, there were 81.48%(132/162)cases with emmetropia. The ratio of refraction-error were no significant difference in-children with normal binocular vision and abnormal binocular vision(P=0.125). CONCLUSION: Among preschool children in Jiangnings Baijiahu district of Nanjing, the main type of refraction error is astigmatism and hyperopia. Esotropia could be found in most abnormal binocular vision children. It is an useful method by retinoscopy and-binocular vision instrument with natural pupil in the half-dark room to survey refraction and primary binocular vision function of preschool children."
