摘　　要：目的通过临床观察儿童握笔姿势，探讨儿童不正确握笔与双眼近视性屈光度差异的相关性。方法横断面研究。排除在南京市中西医结合医院眼科建立屈光档案的儿童中患弱视、斜视及散光大于1.0D者，按男女比1：1随机抽取经确认握笔姿势正确和不正确的儿童各100例。通过睫状肌麻痹验光数锯比较左行眼屈光度差值，以左眼等效球镜度减去右眼等效球镜度的代数值进行统计。对两绀左右眼屈光度差值是衍存仵差异进行Wilcoxon秩和检验结果握笔错误组右眼近视度偏高，与握笔正确组相比差异有统计学意义（Z=-10.33，P〈0.01），且握笔错误组右眼屈光度比左眼高。结论儿童不正确的握笔姿势可能是导致双眼屈光度差异的原因之一，可导致右眼近视度数偏高。Objective To study the relationship between writing strokes and myopic anisometropia in prhuarv school-aged children. Methods It was a cross-sectional study. The refractive data of 100 primary school-aged children who held a pencil in tile eorreet position was collected in the outpatient department of ophthahnolgy, in addition, the refractive data of another 100 priulary school-aged children who hehd a pencil in an abnormal position was collected. All the sereened children who tesled for amblyopia, strabismus or astigmatism higher than L0 D were excluded from the study. The eyeloplegic refractive status of all the screened children was checked and recorded. The difference the two groups＇ refractive status was calculated and compared using a Wilcoxonrank sum test. Results Data analysis showed that the difference between the average degree of anisometropia between the two groups was statistieally significant. The group with the abnormal writing hand position had a higher average degree of anisometropia than the group with the right writing strokes （Z=-10.33, P〈0.01）. And more right eyes had a higher degree of myopia than left eyes. Conclusion An abnormal writing hand position can be an important cause of school-aged children developing myopic anisometropia with right eyes often having a higher degree of myopia than left eyes. Further study is needed on this topic for elarificalion.
