摘要
目的:通过与灯箱视力表的对比研究了解电脑视力表的临床使用价值。方法:选取初三学生63例(126眼)同时用灯箱和电脑视力表进行远用视力检测,对视力检测值进行配对检验。结果:两种视力表检测值的t检验等于1.2671,P>0.20,两种视力表的检测在统计学上无显著性差异。结论:电脑视力表和灯箱视力表在临床上具有相同的应用价值,可以推广和普及。
AIM： To investigate the clinical application value of computer visual acuity chart （CVAC） by comparing with lamp house visual acuity chart （LHVAC）.
METHODS： Sixty-three students （126 eyes） from grade 3 of middle school were detected by LHVAC and CVAC. And the visual acuity results were detected by paired test.
RESULTS： The results showed that there was no statistically significant difference between LHVAC and CVAC （t= 1. 2671,P〉0.02）.
CONCLUSION： CVAC has the same application value compared with LHVAC and is worth promoting.
