兰州市高中毕业班学生视力及屈光状态分析

Visual power and refraction of high school students in graduating classes in Lanzhou city

目的:调查兰州市高中毕业班学生视力及屈光状态,并分析发生屈光不正的危险因素.方法:对本地区5所中学2006/2007年应届高中毕业班学生1572名进行视力测量以及包括裂隙灯、眼底镜、矫正视力等的全面眼部检查.结果:在1572名学生中1409名(89.6%)患有屈光不正.近视是引起屈光不正的首要原因(1237/1572,78.7%),散光为第二位原因(515/1572,32.8%),弱视、斜视、远视和其它眼病的发病率相对较低.男生近视发病率高于女生(84.9%vs72.0%,P<0.05).结论:兰州市中学生屈光不正发病率与国内其它地区类似,采取一定的干预措施保护中学生的视力是有必要的.

AIM： To investigate the visual power and refraction state of high school students in graduating classes in Lanzhou city, and to analyze the risk factors of ametropia. METHODS： 1572 high school students in graduating classes from 5 high schools received the comprehensive visual investigation. RESULTS： A- mong 1572 subjects,ametropia was reported in 1409 （89.6% ）. Myopia was the main reason accounting for ametropia （1237/ 1572, 78. 7%）, and the next was astigmatism （515/1572, 32.8% ）. Amblyopia, anorthopia, hypermetropia, and other eye diseases had comparatively low incidence rate. Ametropia incidence rate was higher in male high school students（691/814,84. 9% ） than in female high school students （546/758,72. 0%, P 〈 0.05 ）. CONCLUSION ： The ametropia incidence rate in Lanzhou area is similar to that in other domestic areas. It is necessary to take certain interventions to protect the visual power of high middle school students.
