一个线性阵列的完整和“混乱”的符号适合测试幼儿已被用来评估35个年轻的弱视。与混乱的阵列测试的敏锐度较差，比那些获得与单一的符号，混乱的阵列和单一的图片acdlties之间的差异是大的敏锐度赤字比小赤字。弱视的深度，指标的眼间差异的敏锐度，是更大的混乱阵列比单一的图片。对于可以用Snellen字母行测试的患者，杂乱阵列的锐度比单个图片或光栅的锐度更接近于行字母的锐度。这些结果表明，混乱的阵列提供了一个更敏感的测试弱视的幼儿比单一的符号或光栅，可能是因为混乱的阵列提出了轮廓的相互作用，利用拥挤现象。
A linear array of intact and “jumbled” symbols suitable for testing young children has been used to evaluate 35 young amblyopes. Acuities with the jumbled array test were poorer than those obtained with single symbols; the discrepancy between the jumbled array and single picture acdlties was greater for large acuity deficits than small deficits. The depth of amblyopia, indexed by the interocular difference in acuity, was greater for the jumbled array than single pictures. For the patients who could be tested with lines of Snellen letters the jumbled array acuities were closer to line letter acuities than single picture or grating acuities. These results suggest that the jumbled array provides a more sensitive test of amblyopia in young children than single symbols or gratings, possibly because the jumbled array presents contour interactions that exploit the crowding phenomenon.
