The Cardiff acuity test was used in estimating the binocular and monocular visual acuity norms of 231 toddlers between 12 and 36 months. Mean binocular acuity increased from 4.5 to 1.2 min arc and monocular acuity from 4.5 to 1.4 min arc over the age range. Interocular acuity difference was not significant and for 99% of the children, the difference in acuity estimate was < or = 1/3 octave. Success rates ranged from 96 to 100% for binocular tests but fell to a range of 41-91% for monocular testing. Acuity assessment was fast and the intraobserver reliability was high. Age norms of visual acuity useful in clinical settings are presented for toddlers between the ages of 12 and 36 months.
卡迪夫视力测试用于评估231名12至36个月大幼儿的双眼和单眼视力标准。在该年龄范围内，双眼平均视力从4.5分视角提高到1.2分视角，单眼视力从4.5分视角提高到1.4分视角。两眼间视力差异不显著，99%的儿童视力估计差异≤1/3倍频程。双眼测试的成功率在96%至100%之间，但单眼测试的成功率降至41%至91%。视力评估速度快，观察者内可靠性高。文中给出了12至36个月大幼儿在临床环境中有用的视力年龄标准。
