摘　　要：在儿童保健及小儿眼科工作中，定量评价婴儿的视觉发育非常重要。本文用选择观看法（ｐｒｅｆｅｒｅｎｔｉａｌｌｏｏｋｉｎｇ，简称ＰＬ）对１５４例生后１０－４０周的正常婴儿进行了视力测试。结果表明婴儿生后视力逐渐提高，约在生后３２－４０周左右即可达到０．２００，并发现母乳喂养儿其ＰＬ视力在２４－２９周要高于人工喂养者。建议在儿童保健工作中推广选择观看法，并提倡母乳喂养。It′s important to detect visual acuity of infants quantitively in children′s health care and pediatric ophthalmology.We detected the visual acuity of 154 normal infants aged 1040 weeks by preferetial looking procedures (PL).The mean visual acuity was inproved correlating with age.It at ained to 0.200 in infants aged about 3240 weeks.We also found PL visual acuity of infants aged 1016w and 2426w by breast feeding was significantly higher than by artificial feeding.We suggested that PL detection is a useful adjunct to the visual acuity evaluation of infants.
