For visual acuity testing in small children Preferential Looking and registration of Visually Evoked Potentials (VEP) are used clinically. Both methods are dependent on good cooperation, since the presented patterns have to be fixated during several minutes by the children tested. In contrast the sweep-technique, described in 1985 by Norcia, allows VEPs to be measured in only a few seconds. As in conventional VEP-testing filtering and Fourier data analysis are performed. The short examination time guarantees in most cases no problems in maintaining attention and stable fixation, even when newborns or handicapped are tested. In several studies good reliability has been demonstrated. As an illustration results of sweep-VEP-testing of three months old twins are shown.
对于幼儿的视力测试，临床上使用优先注视法和视觉诱发电位（VEP）记录法。这两种方法都依赖于良好的配合，因为被测儿童必须在几分钟内注视所呈现的图案。相比之下，诺西亚于1985年描述的扫描技术仅需几秒钟就能测量VEP。与传统的VEP测试一样，需要进行滤波和傅里叶数据分析。短检查时间保证了在大多数情况下，即使测试新生儿或残障儿童时，也不会出现注意力维持和稳定注视方面的问题。多项研究已证明其具有良好的可靠性。作为示例，展示了对三个月大双胞胎进行扫描VEP测试的结果。
