The authors evaluated a preferential looking technique (Teller acuity cards) and a set of gross behavioral indicators (visual function battery) for the ability to rank visually impaired children and infants on the basis of their visual function. Fourteen older children with a diagnosis of cicatricial retinopathy of prematurity who were capable of giving Snellen acuities and a group of 31 preverbal infants with decreased vision due to a variety of causes were tested. Teller acuity card and visual function battery findings were highly correlated with each other (and with Snellen acuities in the older group); however, the Teller acuity cards provided better discrimination in the moderately visually impaired range, whereas the visual function battery was better in the severely impaired range. It is concluded that, in children and infants, visual function over the entire spectrum of low vision can be characterized by using a combination of the Teller acuity cards and the visual function battery.
作者评估了一种优先注视技术（泰勒视力卡片）和一组总体行为指标（视觉功能测试组），以确定其基于视觉功能对视力受损儿童和婴儿进行排名的能力。对14名被诊断为瘢痕性早产儿视网膜病变且能够给出斯内伦视力的大龄儿童，以及一组31名因各种原因视力下降的学语前婴儿进行了测试。泰勒视力卡片和视觉功能测试组的结果彼此高度相关（并且与大龄组的斯内伦视力相关）；然而，泰勒视力卡片在中度视力受损范围内具有更好的辨别力，而视觉功能测试组在严重受损范围内表现更佳。得出的结论是，对于儿童和婴儿，可以通过结合使用泰勒视力卡片和视觉功能测试组来描述整个低视力范围内的视觉功能。
