摘　　要：目的:探究学龄期弱视患儿的数字距离效应。方法:选取2015年1月至2017年1月期间我院收治的98例学龄期弱视患儿为观察组,其中31例患者为7岁组(6~8岁),29例患者为9岁组(9~10岁),38例患者为12岁组(11~13岁)。选取同期来我院进行健康检查的98例健康学龄期儿童为对照组,将其分为7岁组(n=29)、9岁组(n=32)和12岁组(n=37)。比较观察组和对照组儿童不同年龄组对不同数字的反应时、反应时差值,比较不同弱视儿童对不同数字的反应时。结果:数字≥5时观察组7岁组儿童对数字的反应时均长于对照组7岁组患儿,差异具有统计学意义(P<0.05);两组7岁组儿童对数字1、2、3、4的反应时差异无统计学意义(P>0.05)。观察组9岁组患儿对数字1、2、8、9的反应时均长于对照组9岁组患儿,差异具有统计学意义(P<0.05);2组9岁组儿童对数字3、4、5、6、7的反应时差异无统计学意义(P>0.05)。2组12岁组儿童对数字1~9的反应时均长于对照组12岁组患儿,差异具有统计学意义(P<0.05)。观察组患儿7岁组、9岁组和12岁组的反应时差值均低于对照组儿童,差异有统计学意义(P<0.05)。观察组98例患者中轻度弱视患儿对数字的反应时短于中度和重度患儿,中度患儿短于重度患儿,差异有统计学意义(P<0.05)。结论:学龄期弱视患儿对不同数字(尤其是≥5的数字)的反应时较正常儿童均较长,较正常儿童的数字加工能力发展缓慢。Objective：To explore the digital distance effect of children with school age amblyopia. Methods：A total of 98 children with school age amblyopia in our hospital from January 2015 to January 2017 were enrolled. Among them,31 patients were divided into the 7-year-old group（6 to 8 years old）and 29 patients were divided into the 9-year-old group（9 to 10 years old）and 38 patients were divided into the 12-year-old group（11 to 13 years old）. Another 98 healthy children without school age amblyopia were selected as the control group and divided into the 7-year-old group（n=29）,the 9-year-old group（n=32）and the 12-year-old group（n=37）. Reaction time and reaction time difference of different numbers in different groups were compared. Results：When number ≥5,the reaction time in the observed 7-year-old group was significantly longer than that in the control 7-year-old group（P〈0.05）. The difference of reaction time for 1,2,3 and 4 was without statistical significance（P〈0.05）. The reaction time for 1,2,8 and 9 of the 9-year-old group was significantly longer than that in the control group,with statistically significant difference（P〈0.05）. The reaction time for 3,4,5,6 and 7 in two groups was not statistically significant（P〈0.05）. The reaction time for 1 to 9 in the observed 12-yearold group was longer than that in the control 12-year-old group（P〈0.05）. Compared with the same age,the reaction time in the observation group was significantly lower than in the control group（P〈0.05）. Among the observed 98 patients,the reaction time for children with mild amblyopia was shorter than that of children with moderate and severe amblyopia,while the reaction time for children with moderate ambluopia was shorter than that of children with severe amblyopia,with a statistically significant difference（P〈0.05）.Conclusion：The reaction time of children with school age amblyopia is longer than that of the normal children（especially≥5）and the digital processing ability
