儿童图形视力表与Teller视敏锐度卡在婴幼儿视力检测中应用分析

摘要

Objective To evaluate the feasibility and reliability of visual assessment system of Children's Graphic Visual Acuity Chart and Teller Visual Acuity Cards on infants.Methods A total of 185 patients were included in this study from Strabismus and Amblyopia Out-patient Department,Beijing Tongren Hospital in 2012.Among those,118 eyes were checked in 59 infants from 2 to 3 years old with Children's Graphic Visual Acuity Chart,252 eyes were checked in 126 infants from 5 months to 2 years old with Teller Visual Acuity Cards.They were divided into 10 groups according to their age sequence,and every 2 months for one group.The visual acuity was recorded and results were analyzed statistically.Results Visual acuity was obtained with Children's Graphic Visual Acuity Chart,and the results were as follows:0.1-0.2 accounted for 14.41％ (17 in 118),0.3-0.5,64.40％ (76 in 118),0.6 21.19％ (25 in 118); Similarly,visual acuity with Teller Visual Acuity Cards were obtained,the results were as follows:13cy/cm accounted for 21.43％ (54 in 252),4.8-9.8cy/cm 20.63％ (52 in 252),1.3-3.2cy/cm 42.86％ (108 in 252),0.86cy/cm 10.71％ (27 in 252),0.43cy/cm 4.37％ (11 in 252).Conclusions Children's graphic visual acuity chart and Teller visual acuity cards are feasible and reliable visual assessment system on 5 months to 3 years old children.Compared with conventional test,the two visual assessment systems can find abnormal low vision earlier.At the same time,these visual assessment systems can be developed for early intervention and treatment programs on congenital eye disorders in infants with low vision.%目的 探讨儿童图形视力表、Teller视敏锐度卡在婴幼儿视力检测中的可行性和可靠性.方法 对2010年1～12月在北京同仁医院眼科斜弱视门诊就诊的185例患儿,分别使用儿童图形视力表检测2～3岁患儿59例118只眼,用Teller视敏锐度卡检测5个月至2岁患儿126例252只眼.每2个月龄为一组,共分为10组进行视力检测,并对其检测结果进行分析评估.结果 应用儿童图形视力表检测视力结果:0.1～0.2者为14.41％ (17/118),0.3～0.5者为64.41％ (76/118),0.6者为21.19％ (25/118);应用Teller视敏锐度卡检测视力结果:13 cy/cm为21.43％ (54/252),4.8～9.8 cy/cm为20.63％(52/252),1.3～3.2 cy/cm为42.86％ (108/252),0.86 cy/cm为10.71％ (27/252),0.43 cy/cm为4.37％(11/252).结论 儿童图形视力表、Teller视敏锐度卡是一种安全、快速、经济、有效地婴幼儿视力评估检测系统,较常规检查能更早地发现低于该年龄段视力发育水平的低常视力,同时可以对眼部先天性疾患的婴幼儿低视力进行早期干预并制定跟踪治疗方案.
