摘　　要：目的调查及分析郑州市惠济区3～6岁儿童盲和低视力患病率及主要致盲原因，为该地区乃至国内3～6岁儿童防盲治盲工作提供一定的理论依据。方法2012年7月至2013年6月对郑州市惠济区3～6岁儿童进行视力普查，对调查对象首先进行视力筛查，采用国际标准对数视力表查双眼裸眼视力，对任一眼视力低于0．30查最佳矫正视力，若仍低于0．30进一步完成眼压、裂隙灯显微镜、视野及眼底等检查。采用世界卫生组织视力损伤标准确立盲或低视力，并明确主要致盲或低视力原因。结果实际受检9246人，受检率为95．94％。按照世界卫生组织视力损伤标准：双眼盲6人，患病率0．06％；双眼低视力11人，患病率0．12％。儿童双眼盲和低视力的主要原因为早产儿视网膜病变和先天性白内障，单眼盲和低视力的原因均主要由眼外伤引起。结论减少儿童致盲眼病早产儿视网膜病变、防治先天性白内障所致低视力是目前郑州市惠济区防治3～6岁儿童视力残疾的首要任务。Objeetive To investigate and analysis the prevalence of blindness and low vision and the leading causes of blindness in children aged from 3 years to 6 years in Huiji District of Zhengzhou City, and provide a certain theoretical basis to pre- vent and cure the blindness of children aged from 3 years to 6 years in this area and the whole country. Methods A study was carried out from July 2012 to June 2013. Vision screening was used to identify the children aged from 3 years to 6 years. Presenting vis- ual acuity （PVA） and best corrected visual acuity （BCVA） based on autorefraction and subjective refraction were measured separately in each eye. If visual acuity of the best eye was less than 0. 30, further examinations such as intraocular pressure, anterior seg- ment,visual field and ocular fundus were performed. According to the visual impairment standards of the World Health Organization, blindness or low vision were diagnosed. The leading causes of blindness or low vision were investigated. Results A total of 9246 subjects aged from 3 years to 6 years were examined （ 95.94% ）. The prevalence of blindness and low vision were 0.06% （6/9246） and 0.12% （11/9246） ,respectively,ac- cording to the visual impairment standards of the World Health Organization. In this population, the leading causes of dual blindness and low vision were retinopathy of pre- maturity and congenital cataract, while ocular trauma was the leading cause of unilateral blindness and low vision. Conclusion Reducing the low vision caused by retinopathy of prematurity and congenital cataract is the most important task for preventing the blindness in children aged from 3 years to 6 years in Huiji District of Zhengzhou City.
