At present there is no data available on reduced vision and refractive errors in school children of far western Nepal. So, school screening records were used to obtain data useful for planning of refractive services.
Data are provided from school screening conducted by Geta Eye Hospital during February/March 2008. The cases with complete data sets on visual acuity, refractive error and age were included and analyzed using computer software.
Of 1165 children (mean age 11.6 ± 2.5 years) examined, 98.8% (n = 1151) had uncorrected visual acuity of 6/9 and better in at least one eye whereas 1.2% (n = 14) had acuity 6/12 and worse in both eyes. Among them, either eye of 9 children improved to 6/9 and better with correction. However, visual acuity was 6/12 and worse in both eyes of 5 children even after correction. There were 24 children with refractive errors (myopia, 1.54%; n = 18 and hypermetropia, 0.51%; n = 6) in at least one eye. The spherical equivalent refraction was not significantly different with age and gender.
The incidence of reduced vision and refractive errors among school children of this semi rural district were low.
目前,尼泊尔远西部学龄儿童视力减退和屈光不正方面尚无可用数据。因此,利用学校筛查记录来获取有助于规划屈光服务的数据。
数据来自2008年2月/3月Geta眼科医院进行的学校筛查。纳入视力、屈光不正和年龄数据集完整的病例,并使用计算机软件进行分析。
在接受检查的1165名儿童(平均年龄11.6±2.5岁)中,98.8%(n = 1151)至少一只眼睛的未矫正视力为6/9及以上,而1.2%(n = 14)双眼视力为6/12及以下。其中,9名儿童的任意一只眼睛经矫正后视力提高到6/9及以上。然而,5名儿童即使经矫正后双眼视力仍为6/12及以下。至少一只眼睛存在屈光不正(近视,1.54%;n = 18;远视,0.51%;n = 6)的儿童有24名。等效球镜度与年龄和性别无显著差异。
这个半农村地区学龄儿童视力减退和屈光不正的发生率较低。
