We developed a method for testing visual acuity using a general-purpose microcomputer which displays visual acuity targets on a television monitor, controls a staircase psychophysical testing procedure, and provides a printed record of mean visual acuity and standard deviation. This automated procedure can be used to increase the precision of clinical visual acuity testing and to determine if changes in a patient's visual acuity are statistically significant.
我们开发了一种使用通用微型计算机测试视力的方法,该计算机在电视监视器上显示视力测试目标,控制阶梯式心理物理学测试程序,并提供平均视力和标准差的打印记录。这种自动化程序可用于提高临床视力测试的精度,并确定患者视力的变化是否具有统计学意义。
