Abstract

Forced-choice preferential looking (FPL) is a behavioural technique for the estimation of visual acuity in preverbal children. We have constructed an electromechanical FPL apparatus controlled by a microprocessor requiring just one operator. Sixty-three babies aged between six weeks and eleven months were evaluated with an overall success rate of 83% in obtaining an acuity measurement. FPL is a practical method for measurement of infant visual acuity in the ophthalmic clinic setting.

摘要

强制选择优先注视法（FPL）是一种用于评估不会说话儿童视力的行为技术。我们构建了一种由微处理器控制的机电式FPL设备，仅需一名操作人员。对63名年龄在6周至11个月之间的婴儿进行了评估，获得视力测量值的总体成功率为83%。强制选择优先注视法是眼科门诊环境中测量婴儿视力的一种实用方法。
