摘　　要：对四组人的单字视力与并列视力进行了对比研究。发现拥挤现象在１２岁以上的眼病组占２．５％；屈光不正组占２３．２５％，两者均与视力水平无关。正常儿童组４～８岁占４７．６２％，但幅度不大，９～１２岁仅５．５６％，说明正常儿童在视觉发育期存在拥挤现象，弱视组４１．８１％有拥挤现象，且较明显，并列视力与单字视力之差≥５排的占１０．７３％，这对筛选儿童弱视具有一定的临床意义，同时对判断弱视的预后有相当价值。Abstract This article presents a comparative study of fourgroups. We found that the patients with crowdingphenomenon were 4.2%in group of ocular diseasesand 23.25% in the group of ametropia, both ofwhich were not concerned with the visual levcl: Inthe nomal group there was 47.62% within a small ex-tent in 4 to 8 year age and 5.56% in 9 to l2 yearage.The data also showed that there was 41.8%,Inthe group of amblyopia in which the patients withthe extent > 5 rows was 10.72 %(31/289), This hasa definite clinical significance for the distingwishingand predicting of children amblyopia.
