This practical article for clinical electrophysiologists discusses the evaluation of infant and child patients' visual systems using electroretinographic (ERG), electrooculographic (EOG), and visually evoked potential (VEP) techniques. These techniques not only help to secure specific diagnoses, but by systematic assessment of function along the visual pathways can also localize dysfunction underlying visual deficits of pediatric patients. Among children, development as well as disease can affect electrophysiological parameters. Therefore diagnosis of normal or abnormal depends critically on an adequate description of normal responses for age. Procedures that the authors have found feasible, reliable, and valid are summarized. Standardization of pediatric testing appears to be an important next step. The power of ERG, EOG and VEP recordings to demonstrate the neurophysiological basis for pediatric visual impairment is predicted to stimulate further research in this area.
这篇面向临床电生理学家的实用文章讨论了使用视网膜电图（ERG）、眼电图（EOG）和视觉诱发电位（VEP）技术对婴幼儿和儿童患者视觉系统的评估。这些技术不仅有助于做出明确诊断，而且通过对视觉通路功能的系统评估，还能定位小儿患者视觉缺陷背后的功能障碍。在儿童中，发育以及疾病都会影响电生理参数。因此，正常或异常的诊断关键取决于对各年龄段正常反应的充分描述。作者总结了已发现可行、可靠且有效的检查程序。小儿检测的标准化似乎是下一步的重要工作。预计ERG、EOG和VEP记录在揭示小儿视力损害神经生理基础方面的作用将推动该领域的进一步研究。
