目的通过对武汉市92所实施视力健康管理的中小学校学生视力状况进行连续3学年的动态监测,了解学生视力低下状况及变化趋势。方法选择武汉市92所中小学校实施学生视力健康管理,包括培训防控队伍,开展健康教育,实施全人群监测预警、综合干预、建立档案、动态管理。检测学生的裸眼视力低下状况。结果视力低下检出率:2014~2016学年总体的标准化视力低下率分别是:50.83%、51.53%和49.13%。小学阶段3个学年的视力低下检出率逐年下降,由39.62%、39.42%下降到36.97%,差异有统计学意义(P<0.01)。初中阶段3个学年的视力低下检出率分别是:77.75%,80.60%,78.32%,差异有统计学意义(P<0.01)。结论实施视力健康管理的学校,学生的视力低下检出率和视力低下发展速度呈现下降的趋势,学生视力不良状况得到遏制并呈现下降的趋势。
Objective To monitor the visual acuity of 92 primary and secondary school students who have undergone vision health management in Wuhan City for three consecutive years of dynamic monitoring so as to understand the situation and trend of students’ low vision. Methods Ninety-two primary and secondary schools in Wuhan were selected to implement the students’ eyesight health management, including training prevention and control team, health education, monitoring and early warning of the whole population, comprehensive intervention, establishment of files and dynamic management. Detection of uncorrected visual acuity of students. Results Low visual acuity rate: The standardized visual acuity rates in the academic year 2014-2016 were 50.83%, 51.53% and 49.13%, respectively. The detection rate of poor eyesight in three primary school years dropped from 39.62% and 39.42% to 36.97%, respectively, with significant difference (P <0.01). The detection rates of poor eyesight in three academic years of junior high school were 77.75%, 80.60% and 78.32%, respectively, with significant difference (P <0.01). Conclusions The detection rate of low vision and low vision of students in schools and schools with vision health management show a declining trend, and students’ visual acuity has been checked and declined.
