To determine the profile of the visual acuity status, refractive error and other ocular morbidities and to asses the performance at different stages following a vision screening programme in school a retrospective analysis of the data obtained from the programme register for school vision screening programme conducted from April 2003 to March 2006 was done. The data was plotted age and genderwise. Statistical analysis was done to find out disease prevalence with 95% confidence Interval and Z-test was applied for comparison. There were 45,087 students for 239 primary and secondary schools who were examined; 1856 students (4.11%) found having visual acuity .5 or less in either or both eyes. Refractive error was evident in 4.03% students and was the aetiology of compromised vision in 98%. Myopia topped the list with the prevalence of 2.85%; 1733 students (3.84%) were provided with spectacles. Correction of refractive error improved the visual disability in 3.93% of students while amblyopia was found in 0.10%. Average student load per teacher for initial screening was 229. The vision screening programme in school helps to detect refractive error and other causes of compromised vision among large section of children between 5 and 15 years age group. Use of correct spectacles prevents amblyopia considerably. Constraints arising in the programme can be removed by proper planning.
为了确定视力状况、屈光不正及其他眼部疾病的概况，并评估学校视力筛查项目不同阶段的执行情况，我们对2003年4月至2006年3月学校视力筛查项目登记册中获取的数据进行了回顾性分析。数据按年龄和性别进行了绘制。进行了统计分析以找出疾病患病率及95%置信区间，并应用Z检验进行比较。对239所中小学的45087名学生进行了检查；1856名学生（4.11%）被发现一只或两只眼睛的视力为0.5或更低。4.03%的学生存在屈光不正，且98%的视力受损病因是屈光不正。近视患病率最高，为2.85%；1733名学生（3.84%）配备了眼镜。屈光不正的矫正使3.93%的学生视力残疾得到改善，而弱视患病率为0.10%。初次筛查时每位教师的平均学生负荷为229名。学校视力筛查项目有助于在5至15岁的大部分儿童中检测出屈光不正及其他视力受损原因。使用合适的眼镜可大大预防弱视。通过合理规划可以消除该项目中出现的限制因素。
