本文采用隐斜计法测量了110名正常视力儿童的AC/A比率,年龄是6-11岁,得平均值为4.4±1.8△/D,对各年龄组的AC/A比率进行统计学测算P>0.05,无显著性意义.本文结果与孟洋成提出的4±2△/D相近.
In this paper, the AC / A ratio of 110 children with normal visual acuity was measured using the phoria meter. The average age was 6-11 years and the average was 4.4 ± 1.8 △ / D. The AC / A ratio of each age group was statistically calculated P> 0.05, no significant significance.The results of this paper and Meng Yang Cheng 4 ± 2 △ / D similar.
